It doesn't really matter. After failed attempt at adopting "terrorism" as new enemy, USA firmly fixated its sights on China in hopes that a strong enemy will help US regain former prosperity.
What Trump currently is doing fits perfectly this goal. Russia is natural, local ally of USA against China, that's what Trump means when he voices hopes for future cooperation between "our great countries". It is further reinforced by plans to sell F35 to India, another natural ally, which means those planes will be copied by Russia as soon as possible.
In all this Europe is just abandoned. USA knows that in conflict against China, Europe is useless as it has no business in making enemy out of China.
What he might be not appreciating sufficiently (because he percieves Europe as weak and restricted by its morals) is that Europe can be motivated to align themselves with China against Russia. While Europe can't (and doesn't want to) threaten China in any way they can offer China a lot. For starters they could start delivering most advanced litography machines, which only they know how to make to China, instead of Taiwan. And they could also internationally recognize China taking into their zone of influnece eastern parts of Russia if China agrees to provide military assistance and suplemental nuclear deterrence in the war of Europe against Russia that's almost inevitably coming.
I think at some point sobering realization will come that evading your responsibility of global hegemon (even if at this point it's only nominal role) and leaving Europe hanging might have severe consequences for Trump's imperial project.
On the other, please don't over-estimate the competence of the people in charge of Europe (states or EU) — we're still just a bunch of independent sovereign states pootling along quietly doing our own thing with no real hard stressors to force us to select the best of the best as leaders, certainly not a unified cohesive whole.
When it gets to sink-or-swim time, I don't know which way we're going to go. I hope swim, but the US isn't the only one who can snatch defeat from the jaws of victory — that's something every civilisation in history has suffered from, one time or another.
Yeah. The fact that something makes sense doesn't mean it's significantly more likely to happen. But it could. And I'd say that both Russia and USA are now accidentally hellbent on providing sufficient stressors.
