The thing is...
Iran made progress towards getting a nuclear weapon under Obama and under Trump.
I am not sure any plan worked better or worse in preventing their developement.
I personally believe in working with allies.
I also believe that the leaders of Iran are assholes but that doesn't mean all Iranians are assholes.
Perhaps a coup is our only hope.
Once some idiot terrorist gets a hold of a briefcase nuke we are fucked.
IMO... For a good unbiased read on the topic:
