1015 years, and generations to come. i also firmly believe we need to have a robust and open debate about what this means. this is an important part of america's national security that we need to have a debate that recognizes that people on both sides where their concerns. that said, i think it would be a tremendous mistake for congress to vote this down. and for congress to pull back the freehand the president has had this negotiation. i think we need to go in. part of the reason we need to have this debate will become stronger as we go through this. as we talked about on this panel, the types of resources the united states needs in the region are cheap -- aren't cheap, and they aren't free. under our types of other problems we have right now particularly with the defense budget, i think conversation debate this issue understand what is in it, but also commit to understand what it means for america to have a commitments to our own interest, to her allies within the region. only by having that debate, we get stronger coming forward. mr. crowley: i think we're

almost out of time. you have a closing thought? 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 our panel. >> coming up in 10 minutes president obama addressing 500 young leaders from africa. during a white house summit. during that washington
