To be fair not really… other states have been involved in bigger and overall more terrible wars since then. Not USSR/Russia
Chechnya was much shorter and on a smaller scale. Russia has already lost several times more several times more troops in Ukraine than they had during the entire war in Afghanistan (9 years) of course the civilian and Afghan casualties were mich bigger.
Their involvement in other conflicts was indirect, relatively limited or quite short term (Hungary etc.)
Yes, I wasn't really worrying about the indirect/direct distinction, given that the comments I was replying to were trying to make a point about overall global suffering and evil "winning". It doesn't really matter if Russia is invading Ukraine directly or arming insurgents in [insert proxy war here] – the result is still having a hand in creating suffering, and Ukraine is no worse (better in fact by most metrics) than what they've been doing since WWII.
Mind you I don't think the US/UK/whomever has been doing that much better, but Russia is being picked on because that is who menus singled out.
It's one of the most destructive wars, in the style of WW I warfare. Because Russia are basically barbarians in their way of of waging war.
