once you do teradata. think it is a mistake to do that. i would say those who urge some caution. matt: rand paul seemed to be the only one urging caution. to keep to thes agreement at least for the time being because he wants to check to make sure that iran is complying with the agreement. is this the kind of thing where we will be able to know if they are complying you to an everyday? isn't compliance something that needs to be checked years after the agreement? >> that is one of the challenges. i believe that jeb bush also urged some caution, as did john kasich. yes, i think initially there will be an effort on the part of iran, assuming that it votes to confirm this deal, that is something that is now being debated within iran. assuming it goes forward with his agreement, they are likely to comply. as time goes on, the compliance will be less intense and they may seek to circumvent it, so it will require more intensity on the part of the international organizers. -- now toe do dow really sure up the cap
