ms. laipson: i think the u.s. has made a lot of progress with the gcc.the invitation to come to camp david made a difference. within the gcc you have different approaches to iran. the united arab emirates is a major trading partner, there's a person community that lives there. you have a spectrum of views on the sectarian sunni shia problem, and on dealing with iran in general. if you give it the high level of security and deterrence, i agree. when it comes to economic interaction with iran, they have different policies. mr. crowley: john were you going to -- mr. mclaughlan: go ahead. mr. crowley: let me ask about how we strike the balance. what matters suggesting us as a result of this deal, in some degree you have to flex more muscle in the region. we have to not only reassure allies like the saudi's, but demonstrate to the iranians that they can have the run of the place. how do you find a balance between doing that without stumbling into a confrontation that blows of a nuclear deal, blows up whatever fledgling relationship we might have? do you think

ms. laipson: it's not going to be a black-and-white story. the iranians themselves might be political backlash that hasn't been early release to the average iranian citizen. your point is at least partly correct, the other countries will abide by the agreement even if we were by a unilateral political choice to say we change our mind. we don't really want to abide by this agreement. we still have in place lots and lots of unilaterally imposed sanctions. iran is not out of the penalty box. mr. crowley: if you want to bring is in for a landing. mr. mclaughlan: i think would be a bad idea. it's a good idea for congress to debated, because i don't know how you evaluate what we set up here, i think most of us, i would personally say it's pretty evenly balanced, if you add up the advantages and disadvantages of this agreement. there are disadvantages to this agreement. iran gets a lot out of it. we get something out of it. what it is is something we're not very good at, domestically anymore. it is a compromise. >> on that note, thank you so much to
