Sure, but it’s not the US’s job to protect the world. I’m a US citizen, and I’m not a fan of us spending ~5x vs Germany on defense, especially when Germany is such an economic powerhouse in the EU.

I would really like to cut defense spending, but for that to happen, other NATO countries need to increase their defense spending. I absolutely think we should stay in NATO (for the reasons you stated), but NATO is supposed to be an alliance, not a set of countries protected by the US. Yes, it’s in our interest to protect the EU, but it’s also in the EU’s interest to protect the US. We should have each other’s back.
