Can you point me to a isolationist magazine on geopolitics?
The opposite is nationalist not isolationist. Ie doing what’s best for ones country and country men, not the world at large. At least in the context being discussed.
Also you listed “trade” with no qualifier. Is the entire concept of trading a path to one world government? That’s a pretty serious leap in logic.
You may be right but you offer no evidence, only shoot the messenger.
