>> no, i agree with mohse n. he's correct. we don't have alternatives. if we don't have an agreement we don't have reconciliation. but i think there is a plan b, which probably is too late now to approach it in any way. that is i always believed it's a mistake to negotiate with iran on the nuclear issue in isolation of all other issues. by that i mean their activity in the arab world. >> isn't it really hard to get that kind of comprehensive agreement to bring all of these disparate pieces together all together in one grand bargain? >> possibly. but if you take this scenario that is unfolding to its obvious conclusion, at some point sanctions are lifted. what is the incentive for the iranians to curtail their activity that some argue is even more risky and more a threat to western interests than their nuclear program? if you consider their activity now, their influence in the arab world either directly or indirectly, i don't want to generalize. >> you agree with some of the things that genevieve is talking about. >> i do. there are major obstacles ahead
