It doesn't work like that though. They're capitalist countries who function on the same logic as capitalist countries everywhere else.
Tell them to slash welfare to fund imperalist wars and they'll preach about international solidarity and the rules-based order while gleefully taking their citizens money. Tell them to just tank their economies and ruin their capitalist class and that speech switches to the importance of nationalism and self-sufficiency in a heartbeat.
This is just not true at all though. Biden and Obama were both much better at getting Europe to do what they wanted than Trump during his first term. When has Trump being some geo-political mastermind able to bully other countries into submission been anything but a conservative fantasy? He is not even going to get Canada to play ball, let alone all of Europe.
To say that they don't have the ability to resist just giving away their industries is bizzare. You would have to give them genuinely zero other options to survive first, and while Europe is stagnant like most first-world economies, it's still an obscenely wealthy and un-proportionally influential region of the world. It's facing slow economic decline, but it's not in any danger of collapsing anytime soon. To say otherwise just feels like wishful thinking.
Europe is going to decline, that's basically certain, and their relationship with the US souring is going to be a part of that. But it will be slow, as more and more thirld-word countries rise out of poverty and are able to push Europe out of its unique position on the global stage. It's not going to be because they give away all their shit to the US because they couldn't resist Trump's secret genius.
