Well, here's one direct quote:
“What I’ve said is that we need a residual force to start with. So, without putting a precise number or a precise time frame, I’ve set a series of missions that we’re going to have to continue to perform for a decent stretch of time. We’re going to have to continue to provide logistical and intelligence support to the Iraqi military. We’re going to have to continue to provide training to the Iraqi military. We are going to have to continue to protect our diplomatic forces, our civilians on the ground in Iraq. Our embassy, we’ve got to protect. And, I believe we’re going to have to continue to have a counter-terrorism strike force, if not directly inside of Iraq then certainly in the region, that can provide insurance against any resurgence of either Al Qaida activity inside of Iraq or serious, destabilizing violence inside of Iraq. Those are all tasks that we’re still going to have to perform, and that means a certain number of troops. What those troops would be to accomplish those missions, I would leave up to the commanders, or I would at least consult closely with commanders in order to achieve the goals.”
