The call by Prime Minister Nuri Kamal al-Maliki for a timetable for the removal of American troops from Iraq presents an enormous opportunity. We should seize this moment to begin the phased redeployment of combat troops that I have long advocated, and that is needed for long-term success in Iraq and the security interests of the United States.

The differences on Iraq in this campaign are deep. Unlike Senator John McCain, I opposed the war in Iraq before it began, and would end it as president.
