Thursday’s Senate hearing on the Iran nuclear deal hit its nadir when Sen. Ron Johnson, Republican from Wisconsin, lectured Secretary of Energy Ernest Moniz about the dangers of an EMP bomb. Moniz, former head of the MIT Physics Department, could recite more about electromagnetic pulses in his sleep than Johnson could learn in a lifetime. But the deeper absurdity of the scene was that an EMP bomb—an age-old, somewhat mythical worry in certain right-wing circles—has nothing to do with the Iran nuclear deal.
