McNamara Speaks Out on Nuclear Weapons

Robert McNamara who is, for me, a real blast from the past, offers a surprising (coming from him) perspective on nuclear weapons in the May/June issue of Foreign Policy (free, registration required). While he was Defense Secretary under LBJ and ordering secret bombings in Cambodia, I was on the other side of the border in Vietman trying to make sure I was going to get back home in one piece. Well, they say age mellows.

I've excerpted some key passages from a very long article. What I think McNamara does here is remind us of the potential horror we live with every day. It's particularly timely given the nuclear weapons conference that took place this week at the U.S.

At the risk of appearing simplistic and provocative, I would characterize current U.S. nuclear weapons policy as immoral, illegal, militarily unnecessary, and dreadfully dangerous. The risk of an accidental or inadvertent nuclear launch is unacceptably high.

Today, the United States has deployed approximately 4,500 strategic, offensive nuclear warheads. Russia has roughly 3,800.

[...]

How destructive are these weapons? The average U.S. warhead has a destructive power 20 times that of the Hiroshima bomb. Of the 8,000 active or operational U.S. warheads, 2,000 are on hair-trigger alert, ready to be launched on 15 minutes’ warning. How are these weapons to be used? The United States has never endorsed the policy of “no first use,” not during my seven years as secretary or since. We have been and remain prepared to initiate the use of nuclear weapons—by the decision of one person, the president—against either a nuclear or nonnuclear enemy whenever we believe it is in our interest to do so.

[...]

The whole situation seems so bizarre as to be beyond belief. On any given day, as we go about our business, the president is prepared to make a decision within 20 minutes that could launch one of the most devastating weapons in the world. To declare war requires an act of congress, but to launch a nuclear holocaust requires 20 minutes’ deliberation by the president and his advisors.

A 2000 report by the International Physicians for the Prevention of Nuclear War describes the likely effects of a single 1 megaton weapon—dozens of which are contained in the Russian and U.S. inventories. At ground zero, the explosion creates a crater 300 feet deep and 1,200 feet in diameter. Within one second, the atmosphere itself ignites into a fireball more than a half-mile in diameter. The surface of the fireball radiates nearly three times the light and heat of a comparable area of the surface of the sun, extinguishing in seconds all life below and radiating outward at the speed of light, causing instantaneous severe burns to people within one to three miles. A blast wave of compressed air reaches a distance of three miles in about 12 seconds, flattening factories and commercial buildings. Debris carried by winds of 250 mph inflicts lethal injuries throughout the area. At least 50 percent of people in the area die immediately, prior to any injuries from radiation or the developing firestorm.

the Bush administration is planning an extensive and expensive series of programs to sustain and modernize the existing nuclear force and to begin studies for new launch vehicles, as well as new warheads for all of the launch platforms. Some members of the administration have called for new nuclear weapons that could be used as bunker busters against underground shelters (such as the shelters Saddam Hussein used in Baghdad). New production facilities for fissile materials would need to be built to support the expanded force. The plans provide for integrating a national ballistic missile defense into the new triad of offensive weapons to enhance the nation’s ability to use its “power projection forces” by improving our ability to counterattack an enemy. The Bush administration also announced that it has no intention to ask congress to ratify the Comprehensive Test Ban Treaty (CTBT), and, though no decision to test has been made, the administration has ordered the national laboratories to begin research on new nuclear weapons designs and to prepare the underground test sites in Nevada for nuclear tests if necessary in the future.

[...]

[T]he Bush administration’s nuclear program, alongside its refusal to ratify the CTBT, will be viewed, with reason, by many nations as equivalent to a U.S. break from the treaty. It says to the nonnuclear weapons nations, “We, with the strongest conventional military force in the world, require nuclear weapons in perpetuity, but you, facing potentially well-armed opponents, are never to be allowed even one nuclear weapon.”

[...]

Neither the Bush administration, the congress, the American people, nor the people of other nations have debated the merits of alternative, long-range nuclear weapons policies for their countries or the world. They have not examined the military utility of the weapons; the risk of inadvertent or accidental use; the moral and legal considerations relating to the use or threat of use of the weapons; or the impact of current policies on proliferation. Such debates are long overdue. If they are held, I believe they will conclude, as have I and an increasing number of senior military leaders, politicians, and civilian security experts: We must move promptly toward the elimination—or near elimination—of all nuclear weapons.
