Trump is apparently considering a sustained campaign of air strikes against Iran. If the objective of the campaign is to degrade the Iranian nuclear program, that contradicts his claim that the program was obliterated last year. If the point is to reduce the number of Iranian missiles, new ones can be built, so we would only be cutting the grass for the benefit of the Israelis. If the real objective is to facilitate regime change, there is no reason to believe that can be done purely from the air; in addition, since the regime has regained control of the streets, the attack will come too late. Finally, the American public wants no part of another war, and Trump has done nothing to prepare us for it.
What could go wrong?
