他生在美國長在美國，又在美軍中混，要中國國籍何用？

For people born outside China, how many could identify themselves as “黃帝子孫"? Let me tell you, very few. Just because they share the same genetic makeup as the Chinese born in China, they must be Chinese?

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.
