What was so wrong about the post-WW2 order? Any aggression against another state results in action against the aggressor. No "let's free the people of Venezuela", no "let's de-Nazify this part of Ukraine". Etc.?
No borders are re-drawn except by big international consent.
Now, Trump is re-drawing borders like this was his very own board game. But it isn't his. What about China? When will they make a move? US just disrupted their oil in Venezuela and Iran and ... well, let's just say I'm not happy to see what we are heading towards full steam ahead.
