I'm not syaing USA will defintly lose vs china.
but it might be a vietnam kinda thing
heck america cant even win a simple "war" on terror and drugs
That depends on the purpose of the war and what winning for each side means. To me if a U.S.A v. China war erupted teh American goal would be to end Chinese ability to challenge the U.S. for decades. Air superiority and bombing them to the stone age would accomplish that. I don't want their territory. Neither one would be able to occupy and control the other. The territories are simply to large and there are to many people.
