I think people slightly overestimate NATO, but it makes sense why people do. All Russia and China have to do is call their bluffs, aim at London, D.C., Brussels, encircle their proxy armies, disable missiles, stop launches, and things will start descending. Not saying it will be easy or fast or peaceful, but I think the situation calls for more hopeful optimism.
I agree that NATO’s power is overstated and I do believe that in another world war they would lose. However, I am also confident that there will be a war, perhaps not officially declared, between NATO and basically the rest of the world. There is no world where the West will go down without at least trying to maintain their hegemony. They killed to rule planet and they will kill to try and maintain their rule. They will kill but they will not succeed in maintaining their hegemony over the world.
Oh that was not my intention at all, if anything another world war coming up should be a rally for more organization generally, but I see how it could be taken as the opposite.
