It's not being done to appease Trump. Europe has to build up its armies when China, US, Russia, and their proxy allies clearly are. In an ideal world, everyone would stay away from war. Right now, remaining a pacifist that isn't spending on defense is painting a crosshair on yourself. Defense is what has allowed Ukraine to continue to exist against an "empire's thirst for endless war, its military and oil oligarchies and colonization of allies".
The thing that Europe should also be doing is moving out of NATO into their own alliance. When the leaders of those alliances threaten to invade its members, its members should be leaving, not calling its leader pappy. I understand playing politics with democracies who can change administrations, but the US is rapidly ceasing to be one if it hasn't already.
