I’m gonna do my best to communicate my reasoning.

1. Socialists are anti capitalist.
2. NATO is an arm to preserve capitalism.
3. Socialists cannot support NATO. Despite what Vaush says.

The “critical support” theory is based on the assumption that nations wouldn’t come to Ukraine’s aid if NATO didn’t exist. Some believe that America and by extension NATO, created the conditions that preceded the conflict. Capitalism tends to create problems that it then has to solve. There was no salient reason for NATO to continue its existence after the fall of the Soviet Union, other than to maintain US hegemony.
