Which products do NATO countries (read US) exclusively produce?
Imagine Russia groups with China, Iran, North Korea, etc. They exchange currency to trade amongst themselves.
Would NATO countries still have something exclusively in their store that those countries don't have?
The subtle point is why not go against NATO (read US). Why they still can't? Not being rude here, I am having difficulty understanding why haven't there been two distinct groups yet. I am unsure if there has never been distinct groups, even during the cold war, that we know. Please give me a holistic yet concise summary.
I know the question contains two questions. It can't be separated because the essence will be lost.
