we need to be a little more aggressive and less cautionary and collateral damage. we're going to have to step it up. we need special forces on the ground to help us do that so our smart bombs can land where they need to. yes, we need to do more. but at the end of the day this is a bt l that the iraqis are going to have to take and win. and in ramadi it's going to be the famous urban three-block war. that's tough fighting when you get into that urban setting. >> i asked richard clark, the counter terrorisms to both bush and clinton what he thought about the calls for more u.s. troops in iraq. we're hearing a lot of them from republicans on the hill especially those running for president. he said we tried that already, it didn't work out so well. what would you say to a skeptic who says you know we sent 150,000 u.s. troops into iraq. that's not our problem to solve? >> well again, i would argue the premise of the question is not exactly right. did the pullout have an impact?
