Thirteenth Apostle

Suitcase nukes, or atomic demolition devices (ADMs), are actually small nuclear bombs. Both the Soviets and the US had such devices during the "Cold War." They were designed to be carried by Special Operations Forces. These ADMs can be no larger than a king size suitcase. Some were designed for a large backpack. However, if we expand the menu of mininuke delivery systems to include, say, a bowling-ball bag or, better yet, a wheeled suitcase, nothing can be ruled out. Also if we conjure up what in my opinion is an entirely plausible scenario, with a man disguised as a street cleaner, pushing a standard dust cart through busy streets at rush hour--well, strictly from the standpoint of design feasibility, it would be a piece of cake.
