dexter filkins of "the new york times" and greg jaffe of "the washington post." >> the whole thing is to make something that can outlast the american president and make it stable so it once again doesn't become a sanctuary for people like al qaeda, and my overall impression at the moment is that the americans can do that, the americans can do it. it's the afghan part of that that is really, really troubling and i think they're a long way away from that. >> there are limits to what you can do, as dexter said, in kabul because it's so sclerotic there, and that the real diplomacy, where there is room for it potentially is at the local level and i think that's both state department, civilians at the provincial level and military, that's where they have hope and i think that's where they think they can make progress. >> charlie: david petraeus, dexter filkins and greg jaffe coming up. captioning sponsored by rose communications from our studios in new york city, this is charlie rose. >> from our studios in new york city, this is "charlie rose." >> charlie: general david petraeus joins us t
