No outsider has seen Saudi King Abdullah, 87 – and no medical bulletins have been issued – since Dec. 3 when he underwent a second operation, described as “surgery to stabilize several vertebrae on the spinal cord” at the Presbyterian Hospital, New York.  His relatives and the royal retinue have taken over a whole hospital wing and the entire Waldorf-Astoria Hotel, but have maintained an unbroken silence for 18 days about the king’s medical condition.
