Your comment is spot on, but this is strange. It is complex; there are two sides. The ideals of "Western civilization" aren't held by the globe, so it's important to understand why things work the way they do. It isn't "good" versus "evil".
NAP. Don't start nothing, won't be nothing.
Russia started something. There is now something. Failure to respond and restore the equilibrium is tacit acceptance of Russia setting terms, which sets a precedent.
It's pretty clear.
How many more bodies do the mass graves need to qualify as genocide?
By that definition I would say quite a few more mass graves, along with a coordinated effort to stamp out Ukrainian language, customs, intelligentsia, and identity. I understand that Russian state media calls Ukraine "one people" with Russians, but it's a far way to go between a talking point and indiscriminately killing civilians as part of a brutal war and genocide. It's pretty obvious that word is being said for political reasons, not because the current situation obviously meets the definition.
I am absolutely horrified by Russia's war, but I reserve the right to be vastly more horrified if they begin an organized campaign to exterminate the Ukrainian people.
