Apart from accents and gear, what would the difference between playing as Americans and playing as, say, Canadians be? Unless they have a game set in a war in which America had no involvment, they're not going to tell it from another PoV. That would take more research, they'd have to find suitable voice actors, etc. It's easier for them to develop a game with American protagonists because they already know hefty amounts about the U.S. Armed Forces. If CoD was developed by a German studio or a Russian studio, it might be quite different. But it isn't, so it's not.
