...as stated before, I DON'T KNOW WHAT THE ANSWER IS FOR UKRAINE. This is pure speculation but I might imagine spending every hour of every day for the next month or so peeling all the layers apart of the Ukrainian onion to find out what the fuck is really going on and whom we should be defending.
What is indisputable is that Putin didn't invade anywhere during Trump's term.
Fun Facts: Russia invades...
Afghanistan in 1979, Carter is president
1st Chechen War in 1994, Clinton is president
2nd Chechen War in 1999, Clinton is president
Georgia in 2008, Bush is president*
Crimea in 2014, barrack HUSSEIN obama is president
Ukraine in 2022, Joe Biden is president
2008 invasion lasted about 5 days with russian troops occupying Georgia for about 2 weeks. The invasion was prompted by a Georgian attack on disputed territory.
See any correlation here?
