The 1980s were a time of recreational shopping, “morning in America,” and a rare, public debate in the United States over the morality of nuclear deterrence. A high-octane confluence of events contributed to this intense moral debate — the first since the use of nuclear weapons to end World War II. The Reagan administration embraced a doctrine of “prevailing” in a nuclear war with the Soviet Union (which Caspar Weinberger famously defended by arguing, “You show me a Secretary of Defense who’s planning not to prevail, and I’ll show you a Secretary of Defense that ought to be impeached.”)

The United States and the Soviet Union were both accelerating strategic modernization programs, bilateral nuclear negotiations had broken down, mass demonstrations against the Reagan administration’s nuclear policies filled the streets in the United States and Europe, and scientific studies posited that a “nuclear winter” would likely result from large-scale nuclear exchanges.

How serious was this debate? Here’s an indicator: the Catholic Bishops weighed in with a pastoral letter, The Promise of Peace: God’s Promise and Our Response.

One passionate debater was Jonathan Schell, who wrote two elegantly argued books calling for nuclear abolition — The Fate of the Earth (1982) and The Abolition (1984). My shoe box offers the essence of Schell’s argument:

Now, in spite of all we have learned and achieved – or rather, because of it – we hold this entire terrestrial creation hostage to nuclear destruction, threatening to hurl it back into the inanimate darkness from which it came… The fruit of four and a half billion years can be undone in a careless moment.

The choice is really between two entire ways of life. One response is to decline to face the peril, and thus go on piling up the instruments of doom year after year until, by accident or design, they go off. The other response is to recognize the peril, dismantle the weapons, and arrange the political affairs of the earth so that the weapons will not be built again.

The moral cost of nuclear armament is that it makes of all of us underwriters of the slaughter of hundreds of millions of people and the cancellation of future generations.

Unless we rid ourselves of our nuclear arsenals a holocaust not only might occur but will occur”

Joe Nye wrote a rejoinder to Schell and the Catholic Bishops. His slim volume, Nuclear Ethics (1986) is an exercise in moral reasoning that sometimes reads like a Sunday school lesson. Among Nye’s arguments:

The first step in moral reasoning about nuclear weapons should be not to expect too much. Once the moralists enter the realm of contingency, they must tread carefully.

Good moral reasoning is three-dimensional and includes considerations of motives and means. Considering consequences is a necessary but not sufficient basis for sound moral reasoning about nuclear weapons.

Nye offered five “maxims of nuclear ethics:”

MOTIVES:
1. Self-defense is a just but limited cause.
MEANS:
2. Never treat nuclear weapons as normal weapons.
3. Minimize harm to innocent people
CONSEQUENCES:
4. Reduce risks of nuclear war in the near term
5. Reduce reliance on nuclear weapons over time.

Serious stuff. There have been no similarly intense national or international debates over the morality of nuclear deterrence since the 1980s. Many reasons account for this, starting with the end of the Cold War and deep reductions in nuclear weapons.

One notable aspect of the current abolitionist wave is that it is powered by national interest arguments, not moral considerations. Is this a good thing, or a bad thing?
