The US may still well be the protector of the free world, but we've otherwise abdicated our global leadership role. And, with Trump's coyness on US commitment to Article 5 of NATO, whether or not we'll continue to even be the protector in the future is anyone's guess.
There's not a small portion of US society which believes that Trump is a moron and a disaster. I'd wait until after his term to determine whether this is a 4 year fluke or the sign of something bigger.
Nations operate in terms of centuries not 4 years.
