Why would they need heavy lift capabilities to invade the US?
Consider how many young Chinese men of military age are in our universities and working in our tech industries on H1B visas. almost 1.4 million [US residents] were born in China (U.S. Bureau of the Census, 2002)
Like those of Japaneese heritage during WWII, most would be loyal to the U.S.
We usually have several hundred thousand folks visiting China at any one time also.
Wouldn’t count on them as fighters either.
