Was it the promise or was it the SOFA?
On Friday, October 21, 2011, Mr. Obama, invoking one of his campaign promises, announced the complete withdrawal of all U.S. Troops from Iraq by "the [Christian] holidays." Over the weekend, he and his media arm further spun the story, claiming the deadline had been negotiated by G.W. Bush.
Behind the scenes — later paragraphs — we discover that the Pentagon wanted to keep at least 3,000 to 5,000 troops on Iraqi soil. The true number was significantly larger. But they’re all leaving. Why?
It was almost certainly the S.O.F.A., the acronym for "Status Of Forces Agreement."
Obama’s announcement signals that US officials have been unable to negotiate with Iraq’s leaders a renewal of the Status of Forces Agreement (SOFA) governing the stationing and mission of American troops on Iraqi soil. Pentagon officials in particular, backed by a number of congressional leaders, had called for leaving a force of between 3,000 and 5,000 in Iraq for an extended period. –Iraq withdrawal: With US troops set to exit, 9-year war draws to close – CSMonitor.com
A key provision of any SOFA is exempting occupying soldiers from the laws of the country being occupied. It was this provision that Iraqi negotiators refused to renew. Thus, for example, once the old SOFA expired, U.S. soldiers who killed an Iraqi could be tried for murder under Iraqi law.
The Iraqis, it seems, found the back door to get rid of occupying U.S. troops.
This would likely work in other countries as well.
But that still leaves the drones.
