<h2>He promised to continue the withdrawal of troops from Iraq. </h2>
Explanation:
The US involvement in Iraq had been controversial since it started. Under President George W. Bush, American military forces had bombed and invaded Iraq as a "preemptive action." There were rumors of Saddam Hussein (Iraq's leader) having weapons of mass destruction that he was poised to use. It turned out that was not accurate, and the US had over-committed itself to a war zone in Iraq without solid justification for being there.
