Over the past six days, as Trump plunged the United States into a war with Iran, that fantasy of omnipotence has come crashing into reality. Undertaken for unexplained and perhaps unexplainable reasons, the war is being waged in a central node of the global economy against a disciplined, well-armed opponent with nothing to lose. America and Israel killed Ayatollah Ali Khamenei and a dozen Iranian leaders on the first day of fighting, but Trump has clearly given little thought to what comes next. Recklessly, he has ignited a widening conflagration with no obvious end in sight. The death toll has already surpassed 1,000 people.
