他生在美国长在美国，又在美军中混，要中国国籍何用？

For people born outside China, how many could identify themselves as “黄帝子孙"? Let me tell you, very few. Just because they share the same genetic makeup as the Chinese born in China, they must be Chinese? Then there is no Americans in US other than the native Americans: the white are all Europeans, and the blacks are all Africans.

For your information, there were ethnic Japanese solders fighting in US army against Japan during WWII, who are considered as war heros in US as well.
