What materials could terrorists use to make a nuclear bomb?
To make a nuclear bomb requires either highly enriched uranium (HEU) or plutonium. Neither of these materials occurs in nature, and producing either of them requires expensive facilities using complex technologies, almost certainly beyond the capability of terrorist groups. Hence, if all of the world’s stockpiles of nuclear weapons, HEU and plutonium can be effectively protected and kept out of terrorist hands, nuclear terrorism can be prevented: no nuclear material, no bomb, no nuclear terrorism.
