"I know some in Washington would like us to start leaving Iraq now. To begin withdrawing before our commanders tell us we are ready would be dangerous for Iraq, for the region, and for the United States. It would mean surrendering the future of Iraq to al Qaeda. It would mean that we'd be risking mass killings on a horrific scale. It would mean we'd allow the terrorists to establish a safe haven in Iraq to replace the one they lost in Afghanistan. It would mean increasing the probability that American troops would have to return at some later date to confront an enemy that is even more dangerous." G.W. Bush, July 12, 2007
It looks like Bush understood the danger much more than Obama.
