A great deal of Bethesda's intended purpose with Fallout was to create irony, that such a pretentioussuperpower as America fell victim to nuclear war just as the rest of the world. Especially in Fallout 3 that took place in the nation's capital, with every landmark ruined by decades of disrepair. There are several references to communism and homage to not only the art styles, architecture, and culture of 1950s America, but to the Red Scare as well. These events primarily occurred in America and to set Fallout in another country would effectively ruin the game.
