they agreed to 4% under obama which trump ripped up, which was working and the whole world was involved with that agreement.If they thought enriching uranium to 60% gave them power in negotiations they certainly thought wrong, eh? You really believe they were willing to get bombed as hard as they did just for a civilian use only nuclear program?
and again trump was initially negotiating 4% until he started listening to the neo cons and it dropped to 0% which the neo cons knew iran was never going to accept.
