I personally didn't like the Iran deal ( like my opinion matters anyway) but, I strongly believe that when the US makes a deal, we have to stick by it. I know President Trump markets himself as a "deal maker" ,but there is a big difference in business deals and international political deals.........just look at us pulling out of negotiations for the TPP.......when we stopped negotiations the other countries involved didn't throw up their hands and say "oh no the US pulled out what do we do now" , they just kept going and negotiated with China , and they have now taken over our place and we are left with gaining nothing.........
