“These people are, these people are crazy,” President Donald Trump told me in an interview Monday. “And frankly, if they ever had a nuclear weapon, they’d use it within one day,” he said.

I had heard Trump say that before, and because I had, I moved on too quickly from that critical point when he made it. If indeed a president of the United States believes Iran would use a nuclear weapon it built, that president is obliged to do what is necessary to stop what remains of that regime from acquiring a nuclear weapon. Full stop.
