I like the back story to Dust.
But like with anything I like to add my own twists.
In my head in the alternate reality of Dust,the revelation of the alien spacecraft and Germany's tech leap has made the US keep the Los Alamos scientists together after they built "The Bomb"
Together with Einstein and Tesla the US has also invented giant automated 30 foot tall robots.
Armed with a mighty wrecking ball and the frightening Tesla Disintegrator.
Christened, "Kilroy" this engine of destruction dares any Kraut to stick his nose out so he can blast him to kingdom come.
