More like the world no longer needs U.S. leadership. Yeah, the Marshall Plan was a failure of U.S. Leadership. Oh, and the Berlin Airlift, we failed again. I don’t know how our failed leadership kept Stalin and the Russians out of Europe but not only did we stop them but we eventually freed the Baltic states and some others. Oh, and it could not have been the U.S. leadership that brought China out of Poverty and helped them become the second most powerful economy in the World.
I don’t know about how well it will go for the world but I certainly think the U.S. will be better if we let the rest of the world solve its own problems.
