So, let's trust the "brains" of a Cold War apparatus for western dominance, involved in tons of wars, destabilization of governments, and so on, when it comes to how to get world peace...
I don’t think that you understand that the world that you live in is founded on this one fact, and that these “wars, destabilizations, and so on” are but the limited moves available to a board that it otherwise locked down.
You don’t understand the world state, so you’re mad when wars happen, but you cannot compare even large conflicts like Ukraine to a NATO/Russia or NATO/China conflict. It is in a completely different class.
In the context of a NATO/Russia conflict, nuclear weapons are the weapon of choice, while conventional armies are effectively clean up and a way to annoy at your opponent.
So, yes, let’s trust NATO and we could trust the USSR’s Politburo, and the CCP. We thought we could trust Putin, but now we’re not so sure.
