gideon, your thoughts on what do you make of this debate? >> well, it's fascinating because a debate over troop levels, how much force the united states should send, is segueing into a debate on strategy, what strategies the united states use, which is segueing in turn to debate over is the war necessary in the first place? it's fascinating, because everything seems to be up in the air. so you pull one thread and the whole sweater unravels. no one knows which way this is going to go. at the end of the day it's goini to look like where it was a few months ago than dramatically different because the costs are either going big or going out are too high politically for the administration to bear. i think you'll muddle through, but that may not be the most optimal substantive strategy. >> do you think in some ways it's almost become radioactive? >> i absolutely agree with that. you've got a situation that's almost unwinnable for the u.s., any successful counterinsurgency needs at least one legitimate partner, and that's the problem we don't have
