Americans are largely unaware about what's happening in the rest of the world. Reelecting Trump means very few countries will trust the US anymore. Electing him once, ok, a fluke. Twice? The system is rotten and unstable.

I'm fairly sure Ukraine, Canada, Panama, Denmark and the EU as a whole, they're all turning from US allies to indiferent at best. People are actively looking for non US products where they can.

Trump, like Putin, will probably be remembered as the gravedigger for his country.
