challenge at some in congress have already talked about returning to the discussion about imposing tougher sanctions on iran. also within iran some are watching very closely to see the conservatives in that country. there will be calls for the iranian government to withdraw. meanwhile, inside iran you can expect that the inspections are going to get underway. part of this deal calls for almost daily inspectionsment you can expect that to happen. but more importantly against all of this backdrop is going to be the intense negotiations over the course of the next sichx months to try to reach a deal. right now this deal is a temporary onement it is meant to meet short term solutions. the deal to this end standoff once and for all is going to take place over the next six months. veronica? >> thank you so much.
