The bombings of Hiroshima and Nagasaki 60 years ago were stunning and sobering events. They brought World War II to an end, and everyone was thankful for that. Not too many of us stopped to think about the full implications of those bombs for our future. We were too busy celebrating the end of that terrible war.

One of the people who had it absolutely right at the very beginning about the meaning of Hiroshima was the great French writer Albert Camus. He wrote in a French resistance newspaper: “Our technological civilization has just reached its greatest level of savagery. We will have to choose, in the more or less near future, between collective suicide and the intelligent use of our scientific conquests.” We are still facing that choice.
