I'm going to be perfectly honest. I think this thread is a bit idiotic.
There have been many, MANY times in science fiction when this kind of thing has been supposed. Like Firefly? If you're not Chinese or American, you got blow'd the hell up. Like Planet of the Apes? In the original book, France was the supreme power in the world and the protagonists were all french. Like Starship Troopers? Hope you like the world as a Nazi-esque fascist paradise run by the Russians, English and Americans.
Please note that Bioware is not by any means the first person to put their country of origin in a tough spot, either. Remember Fallout? It's a little game where the Chinese and the Americans started hurling nukes at each other. America got blow'd up, and then there's like supermutants and fire-breathing ants running around, not exactly a nice place to live (unless you like slipping live grenades into people's pockets, then it's a virtual paradise).
So anywho, I'll spell it out. It. Is. Fiction. Don't take it so seriously, k? You'll give yourself ulcers.
