On Tuesday morning, a piece was torn out of our world. A patch of blue sky that should not have been there opened up in the New York skyline. In my neighborhood—I live eight blocks from the World Trade Center—the heavens were raining human beings. Our city was changed forever. Our country was changed forever. Our world was changed forever.
It will take months merely to know what happened, far longer to feel so much grief, longer still to understand its meaning. It's already clear, however, that one aspect of the catastrophe is of supreme importance for the future: the danger of the use of weapons of mass destruction, and especially the use of nuclear weapons. This danger includes their use by a terrorist group but is by no means restricted to it. It is part of a larger danger that has been for the most part ignored since the end of the cold war.
Among the small number who have been concerned with nuclear arms in recent years—they have pretty much all known one another by their first names—it was commonly heard that the world would not return its attention to this subject until a nuclear weapon was again set off somewhere in the world. Then, the tiny club said to itself, the world would awaken to its danger. Many of the ingredients of the catastrophe were obvious. The repeated suicide-homicides of the bombers in Israel made it obvious that there were people so possessed by their cause that, in an exaltation of hatred, they would do anything in its name. Many reports—most recently an article in The New York Times on the very morning of the attack—reminded the public that the world was awash in nuclear materials and the wherewithal for other weapons of mass destruction. Russia is bursting at the seams with these materials. The suicide bombers and the market in nuclear materials was that two-plus-two that points toward the proverbial necessary four. But history is a trickster. The fates came up with a horror that was unforeseen. No one had identified the civilian airliner as a weapon of mass destruction, but it occurred to the diabolical imagination of those who conceived Tuesday's attack that it could be one. The invention illumined the nature of terrorism in modern times. These terrorists carried no bombs—only knives, if initial reports are to be believed. In short, they turned the tremendous forces inherent in modern technical society—in this case, Boeing 767s brimming with jet fuel—against itself.
So it is also with the more commonly recognized weapons of mass destruction. Their materials can be built the hard way, from scratch, as Iraq came within an ace of doing until stopped by the Gulf War and as Pakistan and India have done, or they can be diverted from Russian, or for that matter American or English or French or Chinese, stockpiles. In the one case, it is nuclear know-how that is turned against its inventors, in the other it is their hardware. Either way, it is "blowback"—the use of a technical capacity against its creator—and, as such, represents the pronounced suicidal tendencies of modern society.
