The overall strategy has failed, because we have not seen any change in behavior among Iraq's political leaders. And that is the essence of what we should be trying to do in Iraq. That's why I'm going to bring this war to a close.

As president, I will not support driver's licenses for undocumented people and will press for comprehensive immigration reform.
