jiliko The Cost of a Nuclear Arsenal

The $1.7 trillion overhaul is already underway.

To the Editor:

Re “The Staggering Cost of America’s Nuclear Gamble,” by W.J. Hennigan (Opinion, “At the Brink” series, Oct. 13):

Mr. Hennigan says, almost in passing, that “nuclear weapons do deter our adversaries.”

There is a lot to unpack in these six words. There certainly are situations in which one country’s nuclear weapons do deter its adversaries. Russia’s threats to use its nuclear weapons have clearly deterred the United States and NATO from doing more to support Ukraine.

But does deterrence guarantee that these weapons will not be used? Because a failure of deterrence will cause a catastrophe beyond reckoning.

A nuclear war between the United States and Russia could kill hundreds of millions of people in the first afternoon, and the ensuing climate disruption and famine could kill three-quarters of humanity over the next two years. Is there any conceivable benefit that can be derived from possessing these weapons that is worth running this terrible risk?

There have been many near misses already during the nuclear weapons era, crises where certain countries actually began preparations to launch nuclear weapons.

As former Defense Secretary Robert McNamara pointed out, we have not survived this far into the nuclear era because we knew what we were doing. Rather, as McNamara put it, “It was luck that prevented nuclear war.”

The idea that deterrence makes us safe is a dangerous myth. As our highest national security priority, we should be actively seeking a world without nuclear weapons. We don’t know if such an effort can succeed; we have never tried. We do know what will happen if deterrence fails.
