Just a few days ago, the Americans were speaking highly of Kurds as the sharpest sword in the coalition’s arsenal for vanquishing the jihadists. Since Biden’s deal with Erdogan on Wednesday, Washington can forget about the Syrian Kurdish PYG or the Iraqi Kurdish Pershmerga as spearheads of the campaigns to liberate Raqqa in Syria and Mosul in Iraq for ISIS.

*****************************

Syrian Kurdish militia commanders are flouting the ultimatum US Vice President Joe Biden handed them Wednesday, Aug. 24 to retreat to east of the Euphrates or else forfeit US support.  Instead, DEBKAfile’s military sources report, they decided to stand their ground and fight it out with the Turkish army.

The first clash occurred Thursday overnight, when Kurdish forces from Manbij attacked the positions taken by Turkish tanks in Jarablus, hours after Islamic State forces were put to flight from this border town.

The battles continued into Friday morning, Aug. 26.

The US ultimatum to the Kurds was the outcome of understandings US Vice President Joe Biden reached with Turkey’s President Tayyip Erdogan in Ankara on Wednesday, hours after the Turkish army crossed into northern Syria.

“Syrian Kurdish forces will lose US support if they don’t retreat to east bank of Euphrates,” the US vice president stated at a news conference.

Yet Thursday night, Turkish officials made an effort to counteract the impression that their military intervention in Syria was coordinated with the United States. They announce that Russian chief of staff Gen. Valery Gerasimov would be arriving in Ankara Friday for talks with his Turkish counterpart, Gen. Hulusi Akar.

The US commander of American troops in Iraq and Syria, Lt. Gen. Stephen Townsend, had meanwhile instructed all US Special Operations personnel to withdraw from Syrian-Kurdish YPG militia units, and return to the N. Syrian Rmeilan airfield near Hassaka. This is reported from DEBKAfile military and intelligence sources.

The US general also stopped artillery ammo supplies to the Kurdish militia and the transfer of field intelligence from the fighting in areas newly occupied by the Turkish army.

These measures were temporary, the US officers informed Salih Muslim, Syrian Kurdish Democratic Union Party (PYD) leader, and would be lifted after his YPG militia was instructed to pull back from northern Syria and head east of the Euphrates.

Only last week, the Syrian Kurdish militia was riding high, covered in praise for its feat in capturing Manbij with the assistance of US Special Forces.

Their comedown after the US decided to jump aboard the Turkish invasion would be complete, if they complied with the Biden ultimatum. They would forfeit all their hard-won gains from years of combat against the Islamic State, and have to forget their dream of a Kurdish state linking their enclaves along the 900km Syrian-Turkish border.

A stream of information and misinformation is meanwhile muddying the waters as the Kurds in Syria and Iraq absorb the shock of the American turn against them.

The Ministry of Foreign Affairs in Ankara said Thursday that US Secretary of State John Kerry had informed the Turkish Foreign Minister Mevlut Cavusoglu that the US-backed Syrian Kurdish militias had begun their retreat to the eastern bank of the Euphrates River.

US sources qualified this claim, confirming only that a ‘main element’ of the Kurds has retreated, but not the entire force. The Kurds were evidently in no hurry to take any marching orders either from Turkey or the United States.

A short Kurdish statement claimed that their forces had indeed withdrawn to the eastern bank of the Euphrates River, but DEBKAfile’s military sources military sources say that a large body of Kurdish fighters is still in place west of the river. Indeed our sources found Kurdish PYG officers adamant in their determination to stay put and take on the Turkish army.

After the Turkish invasion Wednesday, Kurdish leader Salih Muslim declared, “Turkey will be defeated in Syria along with the Islamic State.”

Kurdish units also took up positions on the roads leading to the US base at Rmeilan, ready enforce a blockade. A Kurdish food convoy due at the base Thursday did not arrive.

In Iraq, there is word of a Kurdish Peshmerga mutiny against US instructors at the bases where they are training for the offensive to recapture Mosul from the ISIS.

However, the events of this week around northern Syria have dealt a major setback to the US-led war on ISIS.

Just a few days ago, the Americans were speaking highly of Kurds as the sharpest sword in the coalition’s arsenal for vanquishing the jihadists. Since Biden’s deal with Erdogan on Wednesday, Washington can forget about the Syrian Kurdish PYG or the Iraqi Kurdish Pershmerga as spearheads of the campaigns to liberate Raqqa in Syria and Mosul in Iraq for ISIS.

Women in Combat: A Terrible Idea Whose Time Has Come?

Women in Combat: A Terrible Idea Whose Time Has Come? Obama wants to send women to fight women-hating Islamofascist militants.

Forcing military women into dangerous combat roles traditionally assigned to men is so potentially disastrous that the next president should waste no time reversing this wrong-headed Obama administration edict, a military advocate recently told Congress.

Of course, parachuting women into combat roles is what happens when fevered left-wing utopianism takes over the Pentagon. Radicals on the Left are animated by a morbid obsession with equality, not by results or even by helping people. To them rigid adherence to politically correct fantasies trumps all other concerns. If soldiers die as a result of nutty policies, left-wingers rationalize that –damn the torpedoes!– it’s just the price that has to be paid for their perverse vision of social justice.

Our bilious, perpetually angry Marxist president despises the U.S. military and everything it represents. Like any good radical leftist, Obama believes the only good American soldier is one who plays the role of social worker, not war-fighter. Putting women into combat situations is another way of weakening America.

Obama hates the military’s personnel, its traditions, its historical accomplishments, and its core mission. He has been gutting and gelding the military since taking office, allowing fleets, warplanes, and weapons to rust their way into irrelevance. He has been going on a human resources rampage by purging the military of ideologically hostile officers, and fundamentally transforming it into something other than a war-fighting force. Obama has been moving to reduce soldier pay and benefits and hollow out the military, reducing it to mid-century staff levels. He’s barely concerned with the continuing neglect of veterans and their health care. The more who perish on waiting lists, the more money that Obama can waste on an ever-expanding array of worse-than-useless social programs designed to buy votes.

The testimony by Elaine Donnelly came after Secretary of Defense Ashton Carter unilaterally decided last Dec. 3 to rescind women’s exemptions from direct ground combat. Secretary of the Navy Ray Mabus and other left-wingers are demanding gender diversity quotas of at least 25 percent and that training standards be lowered for females.

“Current military leaders must follow orders, but the next president will have the power to change existing directives in the same way that the current president imposed them,” Donnelly said in written testimony to the Senate Armed Services Committee, which, earlier this month held its first hearing on women in combat in 25 years. “Leaders of the next administration should be prepared to restore sound priorities, putting the needs of the military first.”

“Men and women in uniform, whose voices have been raised but not heard, are facing situations in which men in the combat arms will be less prepared for the violence of combat, and women will be targets of resentment they do not deserve,” she said.

“The administration is planning to assign significant numbers of minimally-qualified young women to small fighting units, on an involuntary basis, and to send them to fight ISIS and other vicious enemies under conditions that involve higher risks for women than for men,” she warned senators.

“This is being done even though officials are well aware that women’s physical capabilities are far less than men’s and their risks of injury are far greater,” said Donnelly, president of the Center for Military Readiness, an independent public policy organization that reports on and analyzes military/social issues.

“This is not a ‘pro-woman’ policy; it is a cruel deception, betraying the interests of uniformed women who deserve better,” she said.

And women don’t want combat duty, according to an official survey of Army women two years ago. It found that 92.5 percent of the respondents had no desire to serve in direct ground combat units.

“Women should not have to accept double-and-higher injury rates and other career disadvantages competing with stronger men, paying a higher price than men do for volunteering to serve their country,” Donnelly said. “It is also unfair to men – tantamount to telling Navy SEALs that they should execute HALO (high altitude, low-opening) jumps with parachutes known to fail 30% of the time.”

Women are physically ill-suited for combat. That’s just the way it is.

Former Sen. Jim Webb’s (D-Va.) classic essay, “Women Can’t Fight,” laid waste to the idea that putting women in combat was a good idea. The international community agrees: hardly any nations put females in combat roles.

By the way, not letting women fight isn’t an example of workplace discrimination. After all, in what place of employment do people shoot at you? Compare the plight of office workers with submarine personnel. What employees stay in the same office building with the same people for six months at a time with no one leaving the building, while they sleep alongside co-workers stacked three persons high in casket-like bunks?

And if women are up to the task of war-fighting, why don’t they participate in America’s leading contact sport (which is mild compared to combat)? “Since there’s no rule preventing ‘people of either gender’ from playing football in the NFL, why has no woman ever appeared in the Super Bowl?” Phyllis Schlafly wrote recently in a column opposing conscription for women.

But political correctness is more important to President Obama than military effectiveness. He is hellbent on forcing the women of the U.S. military into direct combat units at great risk both to themselves and their fellow soldiers. Military leaders have been cowed by radical feminism. They are promoting change for the sake of ideology, not because it is actually needed.

The same virulent strain of PC infects local fire departments across America, some of which routinely induct women as firefighters. Sure, it may be “equality,” but if you need to be carried down the stairs of a burning building, would you prefer to be rescued by a big strong man or a woman who probably doesn’t have the same muscle power or as much endurance? Some women may be drawn to the idea of fighting fires for a living but very few of them can meet the demanding physical requirements to become firefighters.

But when you’re a left-winger, Mother Nature is your enemy. Science must be brought to heel and subordinated to politics.

Seven years into this catastrophic administration, no patriot needs to be reminded that under this president’s kooky social engineering schemes, the military is becoming a social justice-dispensing expeditionary force, a vanguard leading the way towards the lunatic-left vision of what America and the rest of the world should look like.

Whether the collapse of the military is to be allowed to continue is up to American voters to decide in November.

The IAF’s Achilles’ Heel

The IAF’s Achilles’ Heel Why Israel might wait for the presidential election to sign a new defense deal with the U.S.

This week Prime Minister Binyamin Netanyahu told government ministers that he may wait for the next US president before signing a new military assistance deal with America. Israel’s current military assistance package is set to expire in 2018 and the new package is supposed to include supplemental aid to compensate Israel for President Barack Obama’s nuclear deal with Iran. But to date, the administration has rejected Israel’s requests for additional systems it could use to defend against Iran attacks.

Last October, Defense Minister Moshe Ya’alon asked US Defense Secretary Ashton Carter to provide Israel with a new squadron of F-15s that Israel would outfit with its own electronics systems. Carter reportedly rejected that request as well as one for bunker buster bombs.

Carter instead insisted that Israel use the supplemental aid to purchase more F-35 Joint Strike Fighters, US-made missile defense systems, and the Osprey V-22 helicopter, which Ya’alon didn’t want.

The fact that the administration wants Israel to buy more F-35s instead of F-15s is alarming both for what it tells us about America’s commitment to maintaining Israel’s qualitative edge against Iran and for what it tells us about the F-35, which is set to become the IAF’s next generation combat fighter.

Before considering these issues, it is worth pointing out that the US is not the ally it once was.

This week Britain’s International Institute for Strategic Studies published a report warning that the West’s decades-long military technological superiority over Russia, China and other countries is eroding. The erosion of the West’s military technological advantage over the likes of China and Russia is deeply problematic for Israel. Given the IAF’s complete dependence on US defensive and offensive systems, absent other factors, Israel is imperiled simply by keeping its eggs in America’s basket.

But there are other factors that make continued dependence on the US problematic in the extreme. The erosion of the US’s military technological superiority is matched by its growing weakness internationally. This weakness is most glaring today in Syria.

Last November, Russia deployed an S-400 anti-aircraft system in Latakia. The system is capable of downing jets from a distance of 400 km. Half of Israel, including Ben-Gurion Airport, is within its range. Last December, a member of the IDF General Staff ruminated that never in their worst nightmares did Israeli military planners imagine that the S-400 would be deployed so close to us.

The S-400 ended Israel’s regional air superiority.

It also ended US air superiority.

In late December, Bloomberg reported that right after the Russians deployed the S-400, they began targeting with radar US planes providing air support to rebel forces in Syria.

US officials called Russia’s actions “a direct and dangerous provocation.”

Rather than respond forcefully to Russia’s aggressive move, the US ended all manned flights in the area. It stopped providing air support to rebel forces. There is a direct connection between the US’s docile acceptance of its loss of air superiority in December and the brutal Russian supported assault on Aleppo today.

This week, ambassador Dennis Ross and New York Times military correspondent David Sanger, who are both generally supportive of the Obama administration, published articles excoriating Obama’s policies in Syria.

Ross and Sanger both wrote that Obama was critically mistaken when he said that Russia’s deployment to Syria would not have any significant impact on the region, and that Russia would rue the day it decided to get directly involved.

Sanger noted that the administration’s constant refrain that “there is no military solution” to the war in Syria was wrong.

There is a military solution, it’s “just not our military solution,” a senior US security official admitted to Sanger. It’s Russian President Vladimir Putin’s solution.

Writing in the Los Angeles Times, Ross explained that in deploying his forces to Syria, “Putin aims to demonstrate that Russia, and not America, is the main power broker in the region and increasingly elsewhere.”

In other words, Putin’s involvement in Syria is simply a means to achieve his larger goal of replacing the US as the leading superpower.

This turn of events is dangerous for Israel, not least because the first parties Russia turned to in its anti-American gambit are Israel’s worst enemies – Iran and Hezbollah, along with the Assad regime. By acting in concert, and limiting their operations – as the Iranians have done as well in Iraq – to attacking forces backed by the US, while leaving Islamic State unharmed, the Russians, Iranians, Hezbollah and Bashar Assad make clear that their alliance is first and foremost geared toward reducing US power in the region.

Rather than act on this direct challenge to the US, Obama and Secretary of State John Kerry continue to talk emptily about peace conferences and cease-fires. In so doing their further destroy US credibility as an ally. As America’s primary ally and client in the region, Israel is imperiled by this behavior because it serves to hollow out its capacity to deter its enemies from attacking.

This then brings us to the F-35s and to the IAF’s procurement policies more generally.

Over the past year, the IAF began preparing to take delivery of its first squadron of F-35s. In 2010, Israel placed its first order of 19 planes.

The first two are scheduled to arrive by the end of 2016. The rest are supposed to arrive within two years.

Last year Israel ordered an additional 14 F-35s, and the IAF reportedly wishes to expand that order with an additional 17 aircraft.

By all accounts, the F-35 is an impressive next generation fighter. But at the same time, as Aaron Lerner from IMRA news aggregation service noted this week, the F-35 suffers from one major weakness that arguably cancels out all of its advantages. That weakness is the F-35’s operational dependence on software laboratories and logistics support computers located in the US.

In a manner that recalls Apple’s ability to exert perpetual control over all iPhones by making it impossible for them to long function without periodically updating their operating systems, the US has made it impossible for foreign governments to simply purchase F-35s and use them as they see fit.

As Defense-Aerospace.com reported last November, “All F-35 aircraft operating across the world will have to update their mission data files and their Autonomic Logistic Information System (ALIS) profiles before and after every sortie, to ensure that on-board systems are programmed with the latest available operational data and that ALIS is kept permanently informed of each aircraft’s technical status and maintenance requirements.

“ALIS can, and has, prevented aircraft taking off because of an incomplete data file,” the report revealed.

This technical limitation on the F-35s constitutes a critical weakness from Israel’s perspective for two reasons. First, as the Defense-Aerospace article points out, the need to constantly update the ALIS in the US means that the F-35 must be connected to the Internet in order to work. All Internet connections are maintained via fiber optic underwater cables.

Defense-Aerospace cited an article published last October in Wired.com reporting that those cables are “surprisingly vulnerable” to attack.

According to Nicole Starosielski, a media expert from New York University, all Internet communications go through a mere 200 underwater cables that are “concentrated in very few areas. The cables end up getting funneled through these narrow pressure points all around the globe,” she said.

The Russians are probing this vulnerability.

In October the New York Times reported that “Russian submarines and spy ships are aggressively operating near the vital undersea cables that carry almost all global Internet communications, raising concerns among some American military and intelligence officials that the Russians might be planning to attack those lines in times of tension or conflict.”

According to the report, the fear is that an “ultimate Russian hack on the United States could involve severing the fiber-optic cables at some of their hardest-to-access locations to halt the instant communications on which the West’s governments, economies and citizens have grown dependent.”

Given the F-35’s dependence on the Internet, such an attack, while directed at the US itself, would also ground the IAF’s main combat fighter.

The second reason the F-35’s continuous dependence on a US-based logistics system is a critical weakness is that it would be irresponsible of Israel to trust that the US will not abuse its power to undermine and block IAF operations.

This brings us back to the Pentagon’s insistence that Israel purchase only F-35s and missile defense systems. By giving Israel no option other than purchasing more F-35s, which the Americans control – to the point of being able to ground – even after they are deployed by the IAF, and defensive systems jointly developed with the US and built in the US, the Americans are hollowing out Israel’s ability to operate independently.

Clearly by waiting for the next president to conclude Israel’s military assistance package, Netanyahu is hoping that Obama’s successor will give us a better deal. But the fact is that even if a pro-Israel president is elected, Israel cannot assume that American efforts to erode Israel’s strategic independence will end once Obama leaves office.

George W. Bush, who was more supportive of Israel than Obama, also undermined Israel’s ability to attack Iran’s nuclear installations.

Moreover, given the continuing diminishment of US military power, and America’s expanding strategic vulnerabilities, the possibility that the US will be unwilling or unable to stand by Israel in the future cannot be ruled out.

This week India and Israel were poised to finalize a series of arms deals totaling $3 billion.

The final package is set to be signed during Indian Prime Minister Narendra Modi’s visit to Israel later this year. The deal includes various missile and electronic warfare systems.

In light of the F-35s massive vulnerabilities and the diminishment of US power in the Middle East and beyond, Netanyahu should view India’s enthusiasm for Israeli systems as an opportunity to end the IAF’s utter dependence on increasingly undependable US systems.

Instead of going through with the procurement of the 14 additional F-35s, Netanyahu should offer Modi to jointly develop a next generation fighter based on the Lavi.

Israel’s strategic environment is rapidly changing.

Technological, military and political developments in the region and worldwide must wake our leaders – including IAF commanders – to the fact that Israel cannot afford to maintain, let alone expand, its strategic dependence on the US.

‘No big deal’: Senior Iranian commander says Tehran ready for war with US

No big deal’: Senior Iranian commander says Tehran ready for war with US

 A top commander warned that Iran is ready for an all-out war with US, alleging that aggression against Tehran “will mobilize the Muslim world” against it. The remarks follow Secretary of State John Kerry’s claims that military force was still an option.

Brigadier General Hossein Salami, lieutenant commander of the Islamic Revolution Guards Corps (IRGC), spoke Wednesday to a state-run TV channel as Western powers readied for a new round of talks on getting the Islamic Republic to curb its nuclear ambitions ahead of a June 30 deadline.

He also stated, “War against Iran will mobilize the Muslim world against the US, an issue which is very well known by the enemy.”

Iran recently agreed on a framework deal concerning its nuclear interests with the P5+1 group in Switzerland, which would pave the way for it to be finalized. However, Israel was highly critical of the move. Prime Minister Benjamin Netanyahu stated that it “would not block Iran’s path to the bomb. It would pave it.”

Kerry has recently appeared to try to ease tensions with the Jewish state by assuring it that war was still on the table. This and possible other similar remarks don’t sit well with Salami.

“We have prepared ourselves for the most dangerous scenarios and this is no big deal and is simple to digest for us; we welcome war with the US as we do believe that it will be the scene for our success to display the real potentials of our power,” Salami said, as cited by Iran’s FARS news agency.

The general’s rationale is that past US military victories owe themselves to their enemies’ “rotten” armies – not the case with Iran, he warned.

Addressing the officials currently at the negotiating table, Salami urged them to halt negotiations if any threat of force is issued again by a US official.

Salami echoed the words of Supreme Leader Ayatollah Seyed Ali Khamenei, who in a separate speech remarked that making simultaneous military threats while at the negotiating table will not fly.

“This is not acceptable that the opposite side continues making threats simultaneous with the talks,” he said at a public meeting with teachers in Tehran on Wednesday.

The Supreme Leader also referenced remarks from two US officials whom he did not name, but whom also said action wasn’t completely off the table, saying that: “Negotiation under the ghost of a threat is meaningless and the Iranian nation does not tolerate negotiation under the shadow of threat.”

As for any tangible possibility, Khamenei claimed: “First of all, you can’t do a damn thing.”

“Secondly, as I had already stated during the term of the former US president, the era of hit-and-run attacks is gone and the Iranian nation will not let go of anyone” with aggressive plans on it.

According to the religious leader, this is for the simple reason that the US needs the negotiations as much as Iran does, as it wishes to be seen as the country that put Iran in its place at the negotiating table.

But he added that while it would be best that the crippling economic sanctions by Western powers were lifted, it is “our own planning, will and ability, no matter the sanctions are in place or not,” that is crucial here.

He sent a message to the Iranian negotiators, asking that they “never allow the other side to impose its will, exercise force, humiliate or threaten you.”

Kerry is not alone in appearing to keep the threat of force alive. Last month Republican Senator Tom Cotton (Arkansas) claimed that it would take Washington just several days to destroy Iran’s nuclear facilities.

Cotton was the author of the letter signed by 47 Republican senators and sent to the Iranian leaders, saying that a nuclear agreement made without congressional approval might not last beyond the Obama administration.

On Thursday, the US Senate passed a bipartisan bill that would give Congress review rights over the White House’s Iran nuclear deal.

A faction led by Tom Cotton and Marco Rubio (R-FL) attempted to insert a number of amendments into the bill during the floor debate, including a provision requiring Iran to recognize Israel as a Jewish state.

It echoes the demand of PM Benjamin Netanyahu who wants any final deal with Iran to include a “clear and unambiguous Iranian recognition of Israel’s right to exist.”

Meanwhile, on Monday the Iranian foreign minister addressed Israel on behalf of the 120-nation Non-Aligned Movement, calling that it gives up the bomb, as well as renewing calls for a nuclear-free Middle East.

Israel has not signed up to the nuclear Non-Proliferation Treaty (NPT), though it has sent an observer to the month long conference for the first time in 20 years.

U.S. strategy against Islamic State hits major hurdles

U.S. strategy against Islamic State hits major hurdles, LA Times, 

(Happy Halloween from the Obama Administration. — DM)

The Obama administration’s plan to raise a 15,000-strong rebel army in Syria has run into steep political and military obstacles, raising doubts about a key element of the White House strategy for defeating Islamic State militants in the midst of a civil war.

Pentagon concerns have grown so sharp that Defense Secretary Chuck Hagel sent a two-page memo to the White House last week warning that the overall plan could collapse because U.S. intentions toward Syrian President Bashar Assad are unclear, according to a senior defense official who read the memo but was not authorized to speak publicly.

President Obama has called on Assad to step down, but he has not authorized using military force, including the proposed proxy army, to remove the Syrian leader.

At a news conference Thursday, Hagel declined to discuss his memo to national security advisor Susan Rice, but he acknowledged that Assad has inadvertently benefited from more than five weeks of U.S.-led airstrikes against the Islamic State, one of the most powerful antigovernment forces in Syria’s bitter conflict.

Secretary of State John F. Kerry sought to paper over the problem Thursday, telling a forum in Washington that the proposed proxy army “can have an impact on Assad’s decision-making so we can get back to a table where we could negotiate a political outcome, because we all know there is no military resolution of Syria.”

Rebel leaders in Syria say they would reject joining a U.S.-backed force that is not aimed at defeating Assad, their main enemy.

Senior U.S. military officers also privately warn that the so-called Syrian moderates that U.S. planners hope to recruit — opposition fighters without ties to the Islamic radicals — have been degraded by other factions and forces, including Assad’s army, during the war.

It will take years to train and field a new force capable of launching an offensive against the heavily armed and well-funded Islamic State fighters, who appear well-entrenched in northern Syria, the officers say.

“We’re not going to be able to build that kind of credible force in enough time to make a difference,” said a senior U.S. officer who is involved in military operations against the militants and who asked for anonymity because he was not authorized to speak publicly. “We’ve watched the moderate opposition dwindle and dwindle and now there’s very little left.”

The Pentagon plan calls for putting 5,000 rebel fighters into Syria in a year, and 15,000 over the next three years.

It is the least developed and most controversial part of the multi-pronged U.S. strategy, which also includes near-daily airstrikes in Iraq and Syria, deployment of U.S. military advisors and other support to assist Iraqi government and Kurdish forces, along with attempts to choke off the militants’ financing from oil sales and foreign donors.

When officers involved in high-level Pentagon deliberations in the summer raised concerns about building a rebel army from scratch, they were overruled by senior commanders, who warned that airstrikes alone would not defeat the militants, one of the officers said.

But Pentagon unease has intensified in recent weeks as Jordan and Turkey, two allies that the Obama administration is counting on to help train the proposed proxy force, made it clear that they are lukewarm to the plan, two U.S. officials said.

Washington and its allies are chiefly split over whether the proposed force should focus on reclaiming Syrian territory now held by the Islamic State militants, which is the U.S. priority, or should also battle troops loyal to Assad, the allies’ main concern.

Turkey said this month that it would train a portion of the Syrian force, joining Saudi Arabia in training on its territory. U.S. officials don’t expect to assemble the first group of “moderate” rebels, drawing them from inside Syria or from crowded refugee camps in nearby countries, until early next year at the earliest.

But Turkish officials have signaled that the rebels it trains would concentrate on battling Assad’s forces, not Islamic State, once they return to Syria.

Jordan has not joined the training effort, although it hosts a separate, smaller, CIA-run operation for Syrian insurgents.

U.S. officials say greater involvement by Turkey and Jordan would allow them to increase the number who can be trained, and provide easier conduits for support and resupply when they return to Syria.

The dispute reflects the complex calibrations now in play as the Islamic State militants shake long-established political and military fault lines in the Middle East.

Most dramatically, perhaps, U.S. forces are now in at least tacit alignment with traditional enemies such as Iran and Hezbollah, the Lebanon-based militant and political group, against a common threat.

Syrian rebel leaders and Arab allies complain that the U.S.-led airstrikes have helped Assad by weakening one of his most powerful foes and enabling his army to step up attacks on other rebel factions.

A spokesman for the Free Syrian Army, an umbrella organization claiming to represent largely autonomous rebels in Syria, said fighters were incensed by the U.S. insistence on focusing entirely on Islamic State.

“They have forgotten that tens of thousands of civilians are suffering because of the regime,” said the spokesman, who did not want his name published because it could endanger his family. “Our main cause is the regime, and that will remain our main cause.”

A rebel commander, a defector from the Syrian army who also asked for anonymity, agreed. The U.S. plan “doesn’t work for us,” he said.

“They are concerned with ISIS … but we are concerned with the regime more than ISIS,” he said, using one of several acronyms for Islamic State.

U.S. Central Command, which is overseeing the effort to build a Syrian force, says questions about its direction will be resolved once the fledgling program is underway.

“We are early on in this and there’s much to be figured out,” said Maj. Curtis J. Kellogg, a spokesman for Central Command.

Frederic C. Hof, a former special advisor to President Obama for Syria, said the U.S. plan “is going to be a tough sell” in Syria.

“You can always get people by providing weapons, ammo and pay, but your appeal to a large number of Syrians will increase dramatically if it is a force whose goal is eventually to govern all of Syria,” not just beat one faction, he added.

The caution reflects, in part, a U.S. desire to reassure Iran, one of Assad’s closest backers, that it is not seeking to oust him by force. If the U.S. backtracked on that promise, Iran might step up military support for Assad.

Tehran also could respond by using local Shiite militias to attack U.S. personnel or facilities in Iraq. The Iranian-backed Shiite militias in Iraq have coordinated their attacks on Islamic State with the U.S.-backed government in Baghdad.

“If we really focus on Assad, the Iranian piece of this coalition [against Islamic State] will fracture, and we will have Shia militants trying to target us,” said the senior U.S. military officer.

The U.S. experience with proxy military forces is laced with disappointment.

The Kennedy administration backed a failed invasion of the Bay of Pigs in Cuba in 1961 after training a counterrevolutionary brigade. In the 1980s, the Reagan administration bankrolled the Contras in Nicaragua, who were unsuccessful against the Sandinistas’ socialist revolution.

“We’ve helped arm insurgencies before,” Bruce Riedel, a former CIA analyst who now is a senior fellow at the Brookings Institution. “Nearly all of them have been complete failures or marginal to the final outcome. But there was one spectacular success.”

The CIA, working with Pakistan and Saudi Arabia, covertly poured $4 billion into arming a rebel force in Afghanistan from 1979 to 1989, helping them drive out Soviet forces. Riedel, who wrote a book about the undertaking, said the CIA operation hastened the fall of the Soviet Union and the end of the Cold War.

The Syrian rebel forces, with their fractured leadership and rival sponsors, bear similarities to the competing Afghan mujahedin factions during that war, Riedel said. If the U.S. can secure tight-knit partnerships with neighboring countries on training the rebels, it could also see success against Islamic State.

“There’s no reason we can’t do it again,” he said. “But it doesn’t happen overnight.”
