"1- the agreement does not discuss anything about a complete US withdrawal from Iraq. Instead, it talks about withdrawing "combat troops" without defining what is the difference between combat troops and other troops. It is very clear that the US is planning to stay indefinitely in permanent bases in Iraq (or as the agreement calls them: "installations and areas agreed upon") where the U.S. will continue training and supporting Iraqis armed forces for the foreseeable future."
