There is a version of yesterday’s Oval Office meeting between Donald Trump and Japanese Prime Minister Sanae Takaichi that diplomatic historians will study for a hundred years. Not because it was great. Not because it was consequential. But because it is the clearest possible proof that the most powerful nation on earth handed the nuclear codes to a 79-year-old man who treats geopolitics like a roast at the Friars Club, has the historical literacy of a Golden Retriever who ate the textbook, and apparently cannot sit across from the leader of a country we once bombed into rubble without reaching into the grab-bag of war crimes and pulling out a callback.
