Hard to imagine it's really true. But the Times says it is:
By the end of this month, in accordance with the strategy Mr. Obama put in place after taking office, the American force in Iraq will have shrunk from 144,000 to just 50,000 troops. The remaining “advise and assist” brigades will officially focus on supporting and training Iraqi security forces, protecting American personnel and facilities and mounting counterterrorism operations. Those 50,000 troops are due to leave by the end of 2011.
