Over seven decades have passed since a city was destroyed by a nuclear weapon, but the danger never went away. We are now confronted with a world in which nine nations possess about 15,000 nuclear weapons. The typical weapon in the American arsenal is about 20 times more powerful than the bomb detonated at Hiroshima.
