When President Trump arrived in the snow-covered Swiss Alps on Wednesday afternoon, European leaders were panicking that his efforts to acquire Greenland would trigger a trans-Atlantic conflagration. By the time the sun set, Trump had backed down.

The about-face followed days of back-channel conversations between Trump, his advisers and European leaders, including NATO Secretary-General Mark Rutte and German Chancellor Friedrich Merz, according to people close to the talks. The Europeans, who stood united in their opposition to Trump acquiring Greenland, employed a mix of enticements, such as offers to boost Arctic security, and warnings, including about the dangers to the U.S. of a deeper rupture in the North Atlantic Treaty Organization.

After a meeting with Rutte on Wednesday, Trump called off promised tariffs on European nations, contending that he had “formed the framework of a future deal” with respect to the largest island in the world.

In other words, Trump caved, because Trump Always Chickens Out. I’m sure a massive market drop helped—Trump’s billionaire cronies couldn’t have liked that.

We can also add “framework of a future deal” to “concepts of a plan” and “two weeks” as phrases which succinctly illustrate Trump’s inability to solve real-world problems and offer actual solutions.
