Our larger point is less about nuclear power than how we react as a society to inevitable disasters, both natural and man-made. Because a plane crashes, we don’t stop flying. Because an oil rig explodes in the Gulf, we don’t (or at least we shouldn’t) stop drilling for oil. And because the Challenger space shuttle blew up, we didn’t stop shuttle flights—though we do seem to have lost much of our national will for further manned space exploration. We should learn from the Japanese nuclear crisis, not let it feed a political panic over nuclear power in general.

The paradox of material and technological progress is that we seem to become more risk-averse the safer it makes us. The more comfortable we become, the less eager we are to take the risks that are the only route to future progress. The irony is that one reason Japan has survived this catastrophic event as well as it has is its great material development and wealth.

Modern civilization is in the daily business of measuring and mitigating risk, but its advance requires that we continue to take risk. It would compound Japan’s tragedy if the lesson America learns is that we should pursue the illusory and counterproductive goal of eliminating all risk.
