Don’t count on Trump just mocking Putin. I feel sure Trump knew exactly what was going to happen. He’s not in the least upset about it and neither should you be.
It’s been pretty much a foregone conclusion that Crimea and those two regions are gone, and have been gone for a long time. It’s a bargaining chip for Putin to get what he really wants, a declaration that Ukraine will never join NATO, not unlike the similar agreement there is with regards to Austria.
Trump is an American Nationalist, as am I.
He cares about American interests and recognizes that China is the primary enemy of the US.
However, keep in mind he slaughtered about 200 Russian Spetznaz Wagner guy in Syria when the Russians were caught trying to overrun a Special Ops HQ calling in airstrikes against ISIS. Trump has balls. Biden is ball less.
