Trump's hostility towards [former] allies of US and other observer behaviors makes me think a reason why he is feeding Russian imperialism in Europe is to make them too busy to care about US doing the same to the countries in the American continent. Specially both US neighbors and Panama.

It's like he is subtly proposing a tripartition of Earth among USA, Russia and China, giving Carte Blanche for the other two parties to do whatever they want to their respective promised territories.
