Having pretty carefully considered the arguments for and against leaving troops in Iraq beyond this year, I ultimately found Doug Ollivant's argument to be the most persuasive. So I support the president's decision to end U.S. military involvement in the war in Iraq. But wars, like history, do not stop when America decides it no longer wants to be involved. This is worth remembering, both in terms of what is taking place in Iraq today as well as what might take place in Afghanistan in 2014. So by all means, say U.S. involvement in the war has ended. But think carefully before saying the war has ended.
