[There are dozens here on FR that will side with Ukraine, no matter what. No matter how illiberal they are in all their domestic and international affairs.]
We sided with the Soviet Union during WWII despite its manifest atrocities killing tens of millions and its plans for global subversion. Siding with Ukraine against a Russian attempt to annex it is pretty much a no-brainer. Russia is our enemy, not because we dislike Russians or even Putin, but because the Russian appetite for adding new provinces to its present territory is limitless. That’s the implication when a nation almost 2x the size of the next largest country on Earth occupies and annexes neighboring territories.
“Siding with Ukraine against a Russian attempt to annex it is pretty much a no-brainer.”
Well, except we have no interests there.
