I haven't mentioned the war itself, I've only mentioned the Russia-manufactured border crisis where Belarusian services starve and force push out people onto the Polish border. That's what you're cheering for; using helpless people as meat to throw in a geopolitical grinder.
If you want to have an idea of how it looks there's a movie our last regime attempted to silence; Zielona Granica / Green Border. Feel free to drop the feel-good ending - there's none - nowdays, with the new cheerfully liberal regime the activists cant even reach the border anymore as it's all a militarized zone with hot rounds fired.

But on the issue of war - allowing an empire to size territory is not stopping the war, it's repeating the failed concept of appeasement towards a regime openly discussing it's imperialist aspirations (and history of long and brutal occupation of the entire region). Anti-imperialist struggles are only good if they are against US, and Slavs don't deserve their rights to self determination?
