I’m really not sure why this is a competition, but here’s a short history of the jaw-dropping death Russia has always liked causing, just what I could get from a quick search:
https://en.wikipedia.org/wiki/Circassian_genocide
https://en.wikipedia.org/wiki/Chechen_genocide
https://borgenproject.org/top-12-deadliest-wars-in-history/
specifically or ww2: https://en.wikipedia.org/wiki/World_War_II_casualties#Total_deaths_by_country
Note that I’m counting Russian civillian and military deaths against Russia, which I probably would with the US too, but seems particularly appropriate with Russia, since their main military strategy is just "we have more people and our land is very cold. Attrition and starvation!
oh no, I thought you were just talking about deaths caused. I can start justifying American wars too, if you want to do that, America killed Nazis too, but its strategy wasn’t to sacrifice the meat-shields in Ukraine and then scorched earth the rest of the way until eventually launching a counter-offensive. I mean, whatever works, but damn, it was gruesome.
Lol, the USSR was equally involved in most of those wars, and Russia is fucking around in Syria right now too.
but yeah, nothing Russia did comes close to the proxy wars between Russia and the US.
