I think it’s important to understand that Marxist-Leninists should be supporting the people of both countries, rather than picking one of two capitalist states to back. I understand that Russia has its excuses for doing this, and the Ukraine government has its excuses for what it has done, but it’s important to remember that they are both capitalist countries in the age of imperialism; what they are really after is power. Please feel free to correct me if you believe I got anything wrong.
It is not a bilateral conflict. USA and its allies have worked on creating conditions to cause tensions for decades now. They have also taken material actions against Russia which is not as aggravating as armed conflict but still has noticeable effects. The nation of Ukraine is just a pawn in this fight. Right now what I am hoping for is that peace talks and negotiations are held so that a cease fire can be issued ASAP. But this seems unlikely because it looks like the Ukrainian president has no qualms in shoving his constituents down the meat grinder. Hopefully it doesn’t turn into a slugfest where the only happy folks are the weapons manufacturers.
