The United States told the Iraqi government last week that if it wants U.S. troops to remain in Iraq beyond the deadline of Dec. 31, 2011, as stipulated by the current Status of Forces Agreement between Washington and Baghdad, it would have to inform the United States quickly. Unless a new agreement is reached soon, the United States will be unable to remain. The implication in the U.S. position is that a complex planning process must be initiated to leave troops there and delays will not allow that process to take place.
