Only because I never see this assertion challenged, let me just say out loud:

It does not follow logically that someone who voted against the surge two years ago, and called for a subsequent sixteen-month “date certain” for withdrawal back then, is now vindicated, twenty-four months later, after a Herculean effort on the part of the United States military, by a bilateral agreement, between the USA and an increasingly stable Iraq, to aim for a major withdrawal of US armed forces over the next thirty-six months.
