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.
