I didn't read the suggestion as applying to a war between China and the U.S., but rather, to joining some conflict such as the U.S. in Iraq, or China in Mongolia. (No, I don't think the situations have anything in common besides involving the respective nations in strife.) I say that as a clarification of the discussion, not because I agree that it's a good idea.
