You don’t have to like one or the other though. You can think they both suck.
IMHO, it’s similar to WWII. The both suck, but it was Russia who invaded Ukraine, and continues to randomly attack civilians. That was not a war crime in WWII, but it is today.
Russia is the greater villain in this conflict, but I think Ukraine is not worth the vast sums we are giving them. I don’t know the best way to penalize Russia. Perhaps bleeding their military IS the best way.
