Although canceling the Iran deal and withdrawing from the Paris Climate Agreement (weak as it was) were monumentally stupid and harmful decisions that other presidents may not have made
No argument there, except for the stipulation that Iran would be far better off with nuclear weapons. Even that may not matter in the end though, because imagine a world where nobody gives a shit what the US thinks any more. How many more countries are going to be inclined to put up with Israel’s bullshit without the US backing them up on everything.
