Likewise, you've never changed, always gearing yourself towards double standards, to fit the position of the Chinese, and support them even if they murdered a culture. Of course I don't trust statistics, for reasons stated in my last post.
People in the US join the military for different reasons, not necessarily for some sense of patriotism. The Japanese Ni-Sei in WWII, had two different kinds of American soldiers: (1) Ones that wanted to prove they were as American as the other Americans. (2) Ones that just had to get [themselves and/or their relatives and loved ones] out of the concentration camp by any means. Whichever one anyone chooses, is up to the individual...
You can also replace "Concentration Camp" with "reservation", for the Native-Americans, because their conditions were just about the same (if not worse). Since WWII, many of the people who join the US Armed Forces, join for different reasons: retirement pensions, Montgomery GI Bill (paying off for college), job stability, debt help, etc... Everyone joins the military willingly in America (unless they were drafted, as in the VietNam War), however, of these people who willingly sign away their lives, it's not necessarily for patriotism.
The African citizenship idea, I believe would be pretty similar to the "World-Nation" I've also suggested in earlier posts, please scroll up for reference...
"...when aliens attack earth..." you hope for us to be "earthling-centric"? Once again, you set up a double-standard, in not even advocating the expansionist views of the Aliens. If they have enough technology to travel all this way to Earth, they most likely would possess enough power to wipe us all away, so I guess this means that we should all kneel on our knees, and welcome our new lords, right?
Not to misconstrue however --as many of you do-- I'm not saying we shouldn't go down without a fight, just not out of "earthling centrism": It's out of the hatred for "expansionism and assimilation" of any sort.
