Milky Way?
More like The American Way.

Nah, it doesn't need to be an American thing.
That said, I do believe that Americans need to be first among equals and to be the decisive player in the future space programs and exploration.
It comes with being me. In most ways, I'm a subversion and critic of American patriotism. In other ways (like in the game for example), if the world has to be saved, it has to be saved by an American.
Or we could go with the Interstellar route, where all non-Americans are dead. Which works just as well, except no more Australian/English/Scandinavian women
