We cannot let Iran have a nuclear weapon
According to Donny Dementia they totally and completely obliterated their nuclear program for the next twenty years and in the same sentence said they have to finish the job so the next president in two years won't have to do it.
BTW there was an agreement in place to keep them from having a nuclear weapon, but the black guy did it so it was bad.
Above all else, why would Iran sign an agreement with Dementia Don? He has a proven history in private and public life of tearing up his own agreements on a whim.
Only an idiot defender of fascist genocide would equate protesting genocide as anti-semitism.
