what do you think of this decision, chris harmer? >> it is mission creep.ve guys in the combat situation. personally having spent a lot of time in iraq, i don't see a difference between advising and combat. there's no useful distinction except from a policy perspective. in terms of the efficacy of how you fight isis, we have to set up lily pads. the iraqi security forces aren't up to snuff. they've been defeated every time they've gone up head-to-head with isis. if we want to defeat isis or significantly contain them, we'll have to put more troops. that lily pad strategy from a military perspective will work pretty well, i think. melissa: will it, or is it not enough? it's like getting into ice cold water very slowly. rolling out bit by bit by bit. in many ways, are we setting them up for failure? >> yeah, i think that would be a recipe for failure. a couple billion, $3 billion is not a lot by military standards. it is a lot if you're wasting it. we don't have a strategy to defeat isis. that's not even our announced intention. he just don't have the factors
