Can China defeat America in a war?

The presumption is you are referring to Red China and NOT Nationalist China (Taiwan). Any nation fighting a nuclear war risk's mutual destruction. That's why we had a cold war...no war.

We had already fought Red China once during a conventional war (non-nuclear) during the LIMITED WAR (Limited to conventional weapons) in Korean War (1950-1953). The historian/student will have to study the Korean War, the only available case study on warfare between the US Military verses the Red Chinese Military.

yes! They have more industries to make nuclear weapons more workers etc.The are better supplied then we are.After all,we get alot of our products from them.
