And I want to emphasize DEFENSE. Not "invade other countries in trillion dollar regime change operations". It was US Congress that signed off on the Iraq and Afghanistan wars.
You should note that even Trump held Finland as a counterexample to European NATO countries that don't pull their own weight.
Finland is not a country that spends all it's money on social programs and doesn't have a military. Instead, we still have mandatory male conscription, and a very well-armed reserve.
Historically, we have trusted our defense in the principle of being strong enough that even if we knew that the Soviets/Russians could eventually beat us, the costs we could inflict on them would massively outweigh any possible benefit from conquering us. This no longer works because in Ukraine Putin has shown that he does not do cost/benefit analysis for his foreign policy.
My personal view on the matter is that I support an imperial retreat by the U.S. The EU needs to listen more to the Baltics regarding defense and foreign policy.
That being said, I understand the american feelings about this, as a lot of stuff have had the wrong priorities in the US for a long time, which I would argue is an internal matter and nothing to do with NATO (or its members).

I support a more isolationist U.S. policy. It’s time for America to engage in an imperial retreat.
It does not do it for free. It gets many benefits from "the rest of the world". Like buying US debt, trading oil in US dollars, access to cheap labor, bigger market etc. etc. Nothing of what it does is "free". This giant war spending also helps them to bomb other countries into oblivion when they feel like.
I do believe Trump was correct to criticize the lack of defense spending by many NATO countries and I too think Europeans should largely defend themselves. Personally I favor a multi polar world and would like the U.S. to retreat so to speak.
