The illusion that nuclear weapons are under control

Taking nuclear vulnerabilities seriously, The Hindu, M.V. Ramana,  Benoît Pelopidas, 5 Aug 20, 

All nuclear weapon states have admitted to the possibility that deterrence could fail

Seventy-five years ago, the Japanese city of Hiroshima was destroyed by one single atomic bomb. Three days later, a second bomb destroyed Nagasaki. Those two bombs killed over 2,00,000 people, some of them instantaneously, and others within five months. Another 2,00,000 people or more who survived the bombings of these two cities, most of them injured, have been called the hibakusha. Because of the long-lasting effects of radiation exposure as well as the mental trauma they underwent, the plight of these survivors has been difficult. As Akihiro Takahashi, a hibakusha, testified: “I’ve been living on dragging my body full of sickness and from time to time I question myself. I wonder if it is worth living in such hardship and pain.” But Takahashi and other hibakusha lived on and talked about their experiences in the hope that their plight would never befall       anyone…else

Damage and vulnerability

Over 1,26,000 nuclear weapons have been built since the beginning of the atomic age. Over 2,000 of them have been used in nuclear tests, above and below the ground, to demonstrate their explosive power, causing grave and long-lasting damage to the environment and public health. But this damage is nothing compared to what might happen if some of the existing weapons are used against civilian populations……..

To appreciate why we are vulnerable, we should start by realising that there is no realistic way to protect ourselves against nuclear weapons, whether they are used deliberately, inadvertently, or accidentally. The invention of ballistic missiles at the end of the 1950s, with their great speed of delivery, has made it impossible to intercept nuclear weapons once they are launched. Neither fallout shelters nor ballistic missile defence systems have succeeded in negating this vulnerability. Nuclear weapon states are targets of other nuclear weapon states, of course, but non-nuclear weapon states are vulnerable as well.

The problems of deterrence
……. Deterrence enthusiasts claim that nuclear weapons do not just protect countries against use of nuclear weapons by others, but even prevent war and promote stability. These claims do not hold up to evidence. Nuclear threats have not always produced fear and, in turn, fear has not always induced caution. To the contrary, nuclear threats in some cases have produced anger, and anger can trigger a drive to escalate, as was the case with Fidel Castro during the Cuban Missile Crisis.

After years of having the top operational responsibility for all U.S. strategic nuclear forces, General Lee Butler, former Commander-in-Chief of the United States Strategic Command.  observed: “The goal — the wish, really — might be to prevent nuclear war, but the operational plan had to be to wage war.” It is thus an illusion to think that nuclear war is impossible.

The illusion of control

A related illusion concerns the controllability of nuclear weapons. In the real world, it is not possible for planners to have complete control. However, the desire to believe in the perfect controllability and safety of nuclear weapons creates overconfidence, which is dangerous. Overconfidence, as many scholars studying safety will testify, is more likely to lead to accidents and possibly to the use of nuclear weapons.

In several historical instances, what prevented the use of nuclear weapons was not control practices but either their failure or factors outside institutional control. The most famous of these cases is the 1962 Cuban Missile Crisis. There are likely many more cases during which the world came close to nuclear war but because of the secrecy that surrounds nuclear weapons, we might never know.

If deterrence has not prevented nuclear war so far, what has? While a comprehensive answer to this question will necessarily involve diverse and contingent factors, one essential element in key episodes is just plain luck. This is, again, best illustrated by the case of the Cuban Missile Crisis, where nearly four decades of scholarship attest to the crucial role of luck. The consequences of bad luck, then or later, could make the COVID-19 pandemic seem benign by comparison.

While humanity has luckily survived 75 years without experiencing nuclear war, can one expect luck to last indefinitely?
