I mean most of Chinese "wars" have been border issues. Most of these border issues themselves stem from badly drawn borders post colonial withdrawal. These are understandable, if not justifiable - countries tug at each other to figure out where their territories start/end. A hostile neighbor at your borders is a legitimate national threat

America's wars have been in countries so far away that they could've never posed any threat whatsoever to America as a nation.

Really not the same thing
