Yes. In the end its the usa who unilaterally decides for everyone.

They were both proxy wars. But what were they fighting for? In the cold war, usa wanted vietnam to remain a colony to extract profits, but ussr wanted an ally in the region instead. nowadays usa want ukraine to become a vassal state to destabilize its geopolitical adversaries in the region, specifically russia, much like israel is used against many middle eastern nations. russia has no virtuous intention other than self preservation, and they are not a superpower anymore, so they used the tools they had which was a military operation to disarm ukraine.
