Launched in the hopes of ending months of unrest and quelling the regime's violent crackdown on dissent, the Arab League observer mission has been welcomed by Syria, but the opposition has been critical and called instead for the issue to be taken to the UN.Sudan’s Mohammed al-Dabi, the head of the Arab League monitoring mission to Syria.

THERE have been many remarkable moments in the year of the Arab Spring, but the grainy videos of Syrian protesters pleading for help from the former security boss of another pariah regime must be among them.

The tens of thousands of people who came out of the shadows and the rubble of their embattled city of Homs to make their voices heard knew that for once it was safe to do so. In scenes that defied low expectations of the visit to Syria by a league monitoring mission, protesters were filmed shouting at the delegates, even as gunfire could be heard in the background. ”We are unarmed and dying,” one screamed. ”We are being slaughtered,” said another.

In their desperation, they called on the outside world to intervene and save them from the Syrian army. But it was Lieutenant-General Mohammed al-Dabi, head of the Arab League monitoring mission and a former intelligence adviser to President Omar al-Bashir of Sudan, wanted for war crimes by the International Criminal Court, who was their real target.

He uttered the bland words common to all such men on all such missions. His visit to Homs had been a ”good one”. He would return for more meetings, more visits, more information. But now perhaps none of that matters, for the facts must already have been clear long in advance. The only question is what the various sides of this complex and violent argument will do next.

Will the protesters stay on the streets? If not, President Bashar al-Assad will have won a significant victory, but if they do, they will confirm his worst fears that the Arab League delegation was a Trojan Horse that would only encourage the opposition to his authority.

He would then be forced to confront his own dilemma – whether to redouble the force he has already employed to drive them back into their alleyways, or to allow their movement to grow and be copied around the country, until the true strength of feeling against him is made clear.

Either spells disaster: the use of violence now would destroy whatever credibility he retains in the Arab League. More importantly, now it would put pressure on Russia, on whose support he relies in the United Nations but which is already showing signs of weakening, to allow some form of international action against him.

The conflict in Syria has spread slowly. It would be hard to find in it a turning point equivalent to the fall of Benghazi to the rebels in Libya, or the withdrawal of support from Egypt’s president Hosni Mubarak by the Obama administration.

Tuesday’s encounter in Homs when tens of thousands of Syrian protesters marched on the centre of the city to demand that the Arab League act against the Assad regime could prove to be the moment for which the world has been waiting.
