The unique immorality of nuclear weapons remains apparent 75 years after they were first used in war. On Aug. 6, 1945, Hiroshima was destroyed by a single bomb. Nagasaki was incinerated three days later. 150,000 died in Hiroshima, 80,000 in Nagasaki. Most were noncombatants.
Nuclear weapons have such a terrible moral stigma that they have never been used again. But nuclear deterrent strategy rests upon a sinister paradox. Deterrence means we threaten to use these immoral weapons in hope of preventing their use.
Ethicists have routinely criticized this devil’s bargain, often condemning the mere possession of nukes. In a speech in Hiroshima last year, Pope Francis said, “The use of atomic energy for purposes of war is immoral, just as the possession of atomic weapons is immoral.”
The immorality of nuclear weapons transcends the question of who is right or wrong in a war. Japan was at fault in attacking the U.S. at Pearl Harbor. But the laws of war provide noncombatants with immunity from deliberate attack.
Today, we possess nuclear weapons that are many times more powerful than“Fat Man” or “Little Boy,” the bombs used against Japan. Typical American nuclear weapons such as the B83 bomb are 80 times more powerful.
As destructive power increased, people saw the moral madness of nuclear war. In the 1940s, Albert Einstein urged America to get the bomb before Germany. But in 1955, he signed a manifesto opposing nuclear war, which asked, “Shall we put an end to the human race; or shall mankind renounce war?” In a speech at the UN in 1961, President Kennedy said something similar. “Mankind must put an end to war — or war will put an end to mankind.”
Attempts have been made to ban nuclear weapons. The UN recently sponsored a Treaty on the Prohibition of Nuclear Weapons, signed by more than 80 nations. But the U.S. and other nuclear states have not signed on.
Critics claim the treaty is a pipe dream lacking effective enforcement and monitoring mechanisms. Critics seem to suggest that there is no practical solution other than deterrence.
At one point it seemed that deterrence could coexist with deescalation. After the Cold War ended, there was hope for slow disarmament. But the Trump administration has reversed course, accusing nations such as Russia, North Korea and Iran of nuclear malfeasance. The U.S. now plans to modernize its nuclear arsenal and resume nuclear testing. The last U.S. nuclear test was conducted in 1992. 40 years after the end of the Cold War, a new nuclear arms race seems about to unfold.
The madness of all of this is found in the Cold War phrase “mutually assured destruction.” People have forgotten what this means. But it captures the point of deterrence. To deter a nuclear attack, you threaten to annihilate the enemy in retaliation. The enemy will, of course, threaten the same thing. If the nuclear fuse is ever lit, a chain reaction unfolds, and we all end up dead.
This perverse strategy has worked so far. Nuclear-armed nations have not used their weapons. But the moral logic of the strategy is deeply troubling. It depends upon our willingness to deliberately kill tens of millions of innocent people.
Deterrence also depends upon the rationality, competence and goodwill of those who control the nuclear buttons. But rationality is often in short supply. During the past 75 years, we have witnessed profound failures of leadership and morally suspect uses of force.
In his 1961 speech, President Kennedy warned that nuclear weapons are like the sword of Damocles, hanging over our heads on a slender thread. The fragility of that thread becomes apparent when we consider the extent to which policy is guided by instinct, resentment and wishful thinking rather than by rational calculation.
I have no idea how we might disentangle the vicious web of deterrence or blunt the nuclear sword. But the first step is sober moral reflection. We might begin by reflecting on the horror of Hiroshima as Pope Francis did last year when he said, “Never again war, never again the clash of arms, never again so much suffering.”
MEMORIAL TREE PLANTING
There will be a ceremonial tree planting in the Fresno State Peace Garden to commemorate the 75th anniversary of the Hiroshima bombing, cosponsored by the Human Rights Coalition of the Central Valley, Fresno State’s Ethics Center and the Japanese American Citizens League. Due to COVID-19 restrictions, the event on Aug. 6 at 8 a.m. is invitation-only but will be streamed on Facebook at FresnoEthicsCenter.
