We can agree that China is a more stable partner than the US. My point is that party leadership can also change there, leading to policy changes - it just doesn’t happen as often and there’s usually no dramatic swings when it does. It’s a scale, not a binary thing.

Nah, if the US starts a world war it will suck for literally everyone, not just those voters. You’re likely to be drafted too, regardless of where you live.

In a sense that’s true for any country, though. The only differences are (1) how often the policy changes and (2) by how much. US used to have a 4-year cycle and much less variance in the policies and so it made some sense to get into long-term agreements. Even in the last 8 years, agreements reached by Trump were continued by Biden (e.g. NAFTA). Now though the cycle is like 4 days and the policy swings are 180°, so it only makes sense to enter into extremely short-term, transactional agreements, or if you have no other choice (like Ukraine).
