Imagine how dangerous it would be if NATO was, instead of a defensive pact, a transnational nuclear military helmed by the world's foremost genocidal empire that marches across Europe via propaganda and coup d'etats towards it's ultimate goal of encircling Russia and China. What a cluster fuck that would be? In that reality, if a member state launched a war of aggression NATO would probably support it and continue escalation.

Luckily, we know NATO is a defensive force because it didn't launch multiple wars of aggression, drop depleted uranium on civilians, and is democratically accountable.
