I am massively concerned that Trump may actually win next elections. I keep hearing that's not possible, Americans are not that stupid and so on. But he almost won second time and republicans across whole spectrum seem to love him despite his massive character flaws.
If that happens, US helps to Ukraine stops, period. I would expect Europe is left on its own and that may be a bad time for Ukraine and actually not only Ukraine.
I certainly hope all this is incorrect since I have family and life in Europe.
