I'm not talking about what happens to us if we go isolationist. We tried it and it didn't work too well. I'm asking the guy who says that Trump and the U.S. are a joke in Europe what would happen to Europe without us.
Hell, you bring up a better point that what I originally thought of. How long could Europe and NATO stand in the face of Putin and the Chinese without the U.S.? What happens on the global stage if the meddling and empire building crusaders in the U.S. decide to pull funding and troops from the U.N?
