Ukraine having more direct problems with Russia now, doesn't mean they want the US controlling part of their country.I think Ukraine is far more worried about Russia. It's worry about the U.S. is about how the U.S. is less likely to give it the support it needs to keep Russia from conquering it.
It is true that Trump as President does raise the possibility of a future world divided between three totalitarian nuclear superpowers, but this has not yet happened, it is just a possibility for the future, not the current reality. At present, the U.S. is still useful in keeping China and Russia at bay, it still allows its friends to be democracies, and it may elect a Democratic government at some future time. It's when those things stop being true that it can be equated to Russia and China.
You have one side directly attacking them and the other side threatening and demanding return on their investment via minerals or land.
Both are terrible, but to be fair the latter is actually more disgusting to me. You come in acting like the savior and now you're demanding something in return or they think they're entitled to land....
