No, they don't. But for some reason Trump wants to. Obama and Democrats, and the rest of the world, signed a treaty requiring weapons inspections and the world's monitors said Iran kept their deal.
But Trump unilaterally took the US out of the treaty, and started treating them as the enemy for some weird reason, with tariffs against our own allies for working with Iran as part of the treaty.
So now, they're pinned against the wall by Trump in these extreme acts of aggression. What do you think is going to happen? Peace?
