The Federation of American Scientists has created a Nuclear Weapon Effects Calculator to bring home to Americans the devastating effects of a nuclear blast. Select your nearest U.S. city from the dropdown menu, choose the weapon yield (kilotons or megatons), and designate the delivery method–automobile or aircraft–to reveal in a chilling and deeply disturbing way the area of impact and the degree of destruction.
A quietly compelling case for nonproliferation if there ever was one.
