At some point they might prefer stability and sanity. I would bet that at this point they don't care much either way.
China is playing long, most of the ~unchanging things are in their favor and the US already proved that they're unreliable. People won't forget that soon even if Trump is gone.
Stability and sanity is not happening whether the conflicts stop in Yemen+Hormuz or not. At that point it's just going to go back to tarriff wars and new terror campaigns that the US admin will start somewhere else
