It’s 2020, and America is embroiled in not one but two catastrophic wars: one with Iran that has sucked in the entire Middle East, and another halfway across the world in North Korea sparked by Kim Jong Un test-firing nuclear-capable missiles that could hit the United States. It’s all the worse since the U.S. is waging both wars without allies, all of which have abandoned Donald Trump because of his incessant bullying.

Fortunately, this isn’t where we find ourselves today, but it’s what the president’s critics have been warning could occur if he carries on with policies that have shattered decades of conventional U.S. policy making. It’s not as if their concerns have no factual basis. The Trump administration really did come to the brink of war with Iran and North Korea. In neither case are the underlying tensions that got them there anywhere near resolved. America’s alliances are indeed in flux. But the fact that this is not our reality in 2020 is just as instructive as the fact that it could have been.

This pattern has recurred on several occasions during the Trump era: The president’s detractors foretell doom caused by one of his decisions only to be proved wrong, and then nobody acknowledges that they got it wrong or admits that Trump’s policies have had some advantages.
