https://newatlas.com/nuclear-weapons-satan-missile/46845/ this website does an excellent job debunking a myth that has been around since the 1950s. It seems to be based on pure statistical extrapolation but it is still bunk. People think that 1) because a 15 kiloton nuclear weapon killed 200,000 people in Hiroshima (probably an inflated number) that a 2) nuclear weapon ten times bigger (150 kilotons) would kill ten times as many people 2,000,000 and that a 3) a nuclear weapon ten times bigger than that (1.5 megatons) would kill ten times as many as that (20,000,000). That kind of thinking is of course compete BS. The website above points out that if the most commonly deployed (by the U.S.) strategic nuclear warhead (W8 with a yield of 475 kilotons hit London, it would kill 625,000 people. But if it hit Minot, North Dakota (a key U.S. military base) it would only kill about 3,000. The myths about the lethality of nuclear weapons have hobbled the conduct of U.S. foreign policy for decades.
