“In case we don’t make a deal, we’ll need it,” Trump has said. Iran remains defiant in the face of ultimatums, pledging unprecedented retaliation to any attack.

“I’ve heard this from people who have access deep inside the Pentagon at the highest levels that there are those who say, ‘I think we can handle Iran’s military, their missile strikes now. I think that we can defend adequately,’” said Davis. “I don’t think we can. I think that Iran demonstrated in the 12 Day War that they could penetrate the absolute best integrated air defense systems that we have. I think it’s a bad gamble—not even a bet, but I think it’s a gamble—to say, ‘I think we can sustain this and still knock them out and get their offensive missiles before they have a chance to shoot us.’”
