we heard from the iranian president that the president cannot decertify it unilatera y unilaterally, that is true. but he also said that president is full of accusations. full of insults. that withit was baseless. and he said specifically to the point that president trump made about how iran is sponsoring terrorism. so break that down for us. >> so there's no question that iran has engaged in action ths t the united states hasn't liked in the middle east. there are some areas where iran has done things that the united states wanted it to. in afghanistan iran has been reasonably helpful and on the same page as the united states for much of the last decade. but there are areas, significant areas of disagreement. the iran deal explicitly does not deal with foreign policy in general. regional policy in particular. the iran deal was about one specific thing.
