THERE ARE immutable rules to Middle Eastern wars that not even Donald Trump can change. Once a ceasefire is announced, both sides rush to land one more blow. After the truce starts they sneak in a final volley. For ten hours after the president announced a ceasefire ending the 12-day Iran-Israel war, there were tit-for-tat strikes. By the time he got up on June 24th, Mr Trump had had enough, declaring on the White House lawn, “they don’t know what the fuck they’re doing!” He then called Binyamin Netanyahu and read the riot act. Israel’s jets turned back.
