I finally figured out why you keep coming back:
you want us to educate you. It's subconscious but that's what it is. There's no other logical explanation for why someone can be so consistently wrong and insist on coming back for more punishment.
First, Bush can't be given any credit because if he had left Saddam alone, we wouldn't be in this in the first place. This is still his fault. He set this in motion and it's been up to Obama, and his successor, to clean it up and deal with the long term consequences.
Second, it was his withdrawal timetable that Obama was following.
This article was from 2010
Iraq and U.S. agree that all U.S. forces will withdraw "no later than December 31, 2011." On November 17, 2008, US and Iraqi officials signed a Security Agreement, often referred to as a Status of Forces Agreement (SOFA), stating that "All the United States Forces shall withdraw from all Iraqi territory no later than December 31, 2011." The agreement also called for all U.S. combat forces to withdraw from Iraqi cities "no later than June 30, 2009." [U.S.-Iraq Status of Forces Agreement, 11/17/08]
Bush praised agreement as "another sign of progress." Calling the SOFA "another sign of progress," President Bush said in a November 27, 2008, statement, "The Strategic Framework Agreement sets the foundation for a long-term bilateral relationship between our two countries, and the Security Agreement addresses our presence, activities, and withdrawal from Iraq."
