Any Trumpers that are deranged enough to think that Trump is a global Peace Maker display their ignorance. While Trump would likely do his best to give Ukraine to Russia, Trump is also a long time fellow corrupt BFF with Netanyahu. So while, Biden tries to play both sides in that war, Trump would be all in with Israel. Especially if him and Jared get their palms greased with $$$$.
Remember that Trump's foreign policy is totally self interest. The dictators around the world speak his language of corruption so he will sell of our foreign policy to them. Many of our allies don't speak Trump's "what's in it for me" language so Trump will abandon allies in a NY minute.
Never forget. Trump believes in nothing. His viewpoint can change from day to day to benefit himself.
