Trump does not think strategically, historically, geographically, or even rationally. He does not connect actions he takes on one day to events that occur weeks later. Allied leaders know that if they help him in the Gulf, he won't be grateful, or even remember www.theatlantic.com/ideas/2026/0...

Everyone but Trump Understands What He’s Done
Allied leaders know that any positive gesture they make will count for nothing.

German digital campaigning is so weird. There's a fraction over three weeks to the election, and the biggest parties are doing *nothing* with digital ads. E.g. SPD and CDU are spending around 1/20th of what Labour and the Tories were spending in the UK with three weeks to go last summer.
