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.
There are so many good reasons why we should critically support Russia against the west in the current political climate. The reality is very far from just capitalist country vs capitalist country as if it were in a vacuum with no other nuances.
