This is a hypocritical take. You’re specifically using the cold war as an example and claim that US vassalage is better and not actually vassalage compared to the Soviet Union. That just isn’t true.
Also you cannot just leave NATO. Leaving the EU is hard, but at least still possible. For explanation please look at the elections results of the past decades of any western country. You’d get a whopping 80-95% across the board for pro-NATO parties.
If a country were to somehow still leave NATO they’d likely face a quick invasion unless they lower themselves to ally with Russia and get guarantees.
As for the Cold War politics worked differently on both sides. The American hegemony is less implicit but still exist through it’s prevalent cultural hegemony. Consent is manufactured to stay aligned with the US up to this day. You can see this influence in official government policies, in the mass media and in the education system.
This is pure semantics.
If you can never vote for leaving NATO, then you factually cannot leave it.
