The Chinese may (or may not ~ who's to know, really?) have a disadvantage vs. the US in regards to the technology of various armaments.
One inarguable fact is they by far have an incredible advantage in regards to sheer numbers. Monstrous amounts of manpower can easily be a deciding factor in a military conflict. I have no doubts that the Communist government there would throw wave upon wave upon wave of people until we were simply overrun should a real conflict ever arise between us and them. Kill 100 of them? They'll send 1000 more. Kill 1000 of them? They'll send 10,000 more. Kill 10,000 of them? They'll send 1,000,000 more.
When you have a population of over a billion the number of people their rulers would find easily expendable could be simply staggering.
Just a thought...
