All of human history is manipulated by the Tralfamadorians to get a single piece of metal to Titan to repair the Tralfamadorian spaceship. The army officers, you, me, everybody, we are all the result of Tralfamadore's plan.
> In Sirens of Titan, there’s this army of Mars which is really a joke. No one in the army, [not] even the officers, are really in charge of what’s going on. They’re all mind controlled. Nobody has any real free will. They’re just set up as a pawn to be sacrificed, to make Earth come together, kind of Watchmen-style.
