why don't we meet behind closed doors and have the negotiation that president obama said he wants so much. >> greta: any chance that will happen? >> if i were president obama, i wouldn't do it. if i were candidate obama i never would have proposed it to begin with. i think ahmadinejad is in a position now where he doesn't have anything to lose by asking for those negotiations. it could put the president in a difficult position. >> greta: we can't live with at least, so we've said, with a nuclear armed iran and neither can israel. so there's sanctions. president ahmadinejad today made some crack about 4,000 sanctions it is not going to make a bit of difference. if we take military action against iran, how does it play out? >> assuming it was the united states, i think it would be a successful effort. i think we have the capability at least based on what we know of the program to destroy it.
