“ The conventional bombs of World War II were called “blockbusters”, filled with 20 tons of TNT, they could destroy a city block. All the bombs dropped on all the cities during World War II amounted to some 2 million tons of TNT — two megatons…Today, two megatons is the equivalent of a single thermonuclear bomb — one bomb with the destructive force of the second world war. But there are tens of thousands of nuclear weapons. The missile and bomber forces in the Soviet Union and United States have warheads aimed at over 15,000 designated targets. No place on the planet is safe. The energy contained in these weapons totals far more than 10,000 megatons; but, with the destruction concentrated efficiently, not over six years but over a few hours. A blockbuster for every family on the planet; a World War II every second for the length of a lazy afternoon.”
