The premise is off. These aren’t "everyone else’s problems", NATO, the UN, trade stability, and foreign aid exist because they serve US interests too: security, markets, alliances, and predictability. The US isn’t benevolently carrying the world; it’s investing in systems that reduce the cost of conflict and instability later.

The question isn’t whether the US is allowed to stop spending, but what it wants the world to look like if it does.

It's just the case that some people at the top don't seem to understand that.
