Trump no doubt hopes that he can slip away without Americans noticing the magnitude of this defeat. The financial markets may stabilize if it is clear that oil will eventually start flowing again through a reopened strait, even if under the new Iran-controlled system. A major strategic setback for the United States need not affect Wall Street. The president may also hope that he can change the subject by launching another military operation, this time against the government in Cuba. And the news media have indeed begun writing more about Cuba than about the unfolding disaster in Iran.

According to one U.S. official, Netanyahu’s “hair was on fire” after the call with Trump—for good reason. The Iran war may end up as the single most devastating blow to Israel’s security in its brief history. On the present trajectory, Iran will emerge from the conflict many times stronger and more influential than it was before the war. It will exercise leverage with dozens of the richest nations in the world, all of which will have an acute interest in keeping Iran happy. They will be unlikely to take Israel’s side in any conflict that it has with Tehran or with its proxies in Lebanon and Gaza, because Iran will have the means to punish them if they do. Israel will emerge more isolated than it has been at any time in its history—and not least from its only reliable protector, the United States. When Trump turns his back on Israel, as he must do to implement this policy, MAGA will gladly follow. The bipartisan anti-Israel consensus in the United States will grow and harden.
