Even before election, Trump is roaring. Screams of taking over the Panama Canal, Canada and Greenland. Promises of tariffs on, essentially, everyone. Lots of domestic threats about immigrants and going after Democratic politicians. At the same time his proxies, like Musk, muse on slashing Social Security and Medicare.
Europe’s in particularly tentative position: threats of tariffs and forcing Europe to spend more of its money on defense, by which Trump means “buying more US weapons.”
Western Europe has been an American satrapy since WWII. The Americans invaded and never left, and have had the Euros under the economic thumb the entire time. When necessary they have overthrown governments and they have every politician of note under surveillance.
Eastern Europe fell under the thumb after the collapse of the USSR and were, mostly, happy to do so.
