If the US became completely isolationist, including pulling out all support from NATO and dismantling the nuclear umbrella, I’d predict the next Franco-German war in 20 years max (possibly sooner).
Which what credence?
Why the heck should Germany want to wage war in the next 20 years on France?
Why should an isolationist US lead to a weaker EU instead of the EU coming more together?
