Iran can sea-launch from off our coasts. Germany planned this in World War II. Subsequently, the U.S. completed 67 water-supported launches, ending as recently as 1980; the U.S.S.R. had two similar programs; and Iran itself has sea-launched from a barge in the Caspian. And if in 2007, for example, 1,100 metric tons of cocaine were smuggled from South America without interdiction, we cannot dismiss the possibility of Iranian nuclear charges of 500 pounds or less ending up in Manhattan or on Pennsylvania Avenue.

The probabilities of the above are subject to the grave multiplication of nuclear weapons. Of all things in respect to the Iranian nuclear question, this is the most overlooked. A 1-in-20 chance of breaking a leg is substantially different from a 1-in-20 chance of dying, itself different from a 1-in-20 chance of half a million people dying. Cost drastically changes the nature of risk, although we persist in ignoring this. Assuming that we are a people worthy of defending ourselves, what can be done? …

Any president of the United States fit for the office should someday, soon, say to the American people that in his judgment Iran—because of its longstanding and implacable push for nuclear weapons, its express hostility to the U.S., Israel and the West, and its record of barbarity and terror—must be deprived of the capacity to wound this country and its allies such as they have never been wounded before.
