The main purpose of "nuclear weapons" (which doesn't exist) is to give the illusion that there is some power balance in the world that needs to be respected or else the bomb. Coincidentally this ties in with the supposed American military superiority which I am also sure is beneficial in the sense that mutt zogbots feel like they are invincible when they die in the sand in the middle-east so that the Jews can hold on to that piece of land for a short while.
