Happy New Year!

There have been five particularly horrific years of living dangerously in the nuclear age. The first was, most jarringly, 1945, when the Bomb made its spectacular appearance. No advance in the history of warfare was more jarring than a city-killing weapon that could be delivered by surprise for which there was no defense.

The second period of maximum danger was 1949-1950, when the Soviet Union tested its first atomic bomb, President Truman endorsed a crash program to proceed with far more powerful thermonuclear weapons, the People’s Republic of China was born, and the Korean War began. It was an open question whether or not atomic bombs would again be used to end a prolonged land war in Asia that was at times going very badly for the United States before it ground to a bitter stalemate.

The third year of living dangerously was 1962, when the Cuban missile crises played out over thirteen days. This crisis occurred at a time when there were no tacit rules of engagement between the Superpowers and before the era of communication satellites or “hotlines.” (It took half a day to code, transmit, via Western Union, and translate Nikita Khrushchev’s first letter to President John F. Kennedy.) In the meantime, dramas unfolded in a matter of minutes that could have changed the course of planetary history.

The fourth year of living dangerously was 1983, the year that President Ronald Reagan declared the Soviet Union to be the focus of evil in the world, when he surprised nearly everyone by announcing the Strategic Defense Initiative aimed at providing an astrodome-like protection against missile attack, Soviet air defense forces shot down a Korean Airlines plane with a Congressman on board that had strayed hopelessly off course, the United States began to deploy new missiles based in Western Europe, and the Kremlin walked out of nuclear negotiations.

The fifth year of living dangerously was 2001, when Americans became acutely conscious of their vulnerability due to the seething rage of nineteen young men, mostly Saudi, who used jet fuel as bombs against the Twin Towers and the Pentagon. These attacks unhinged the U.S. electorate sufficiently to endorse the prosecution of two prolonged wars that are unlikely to be worth the great sacrifices of their prosecution.

Anxiety produced by years of living dangerously remains in the bloodstream of the body politic for many years afterward. Political debate and poor decisions thrive on anxious metaphors – Munich is still a hardy perennial – even when the passage of time dulls their import and relevance. Because anxiety takes refuge at the cellular level, threat inflation never grows old: we always overreact to jarring events.

The Bomb and insecurity are inseparable. Nuclear weapon requirements advance during years of living dangerously and then recede over time, leaving remnants of force structure behind. The Bomb doesn’t help major powers get what they want in this world. Still, attachment to the Bomb, like anxiety, is a hard habit to break. Nuclear weapons continue to be especially useful for states that are not good company, but do not wish to be ignored or leveraged by stronger powers.

US presidents of quite different persuasions have managed to implement cooperative arrangements for threat reduction to help prevent new nightmares related to the collapse of the Soviet Union and the advent of messianic terrorism. Republican and Democratic presidents have also maintained and updated frameworks to reduce old-fashioned nuclear threats, largely by means of treaties, reducing global stockpiles by 70 percent.

This track record of reducing nuclear dangers and avoiding nuclear nightmares rivals all other diplomatic accomplishments since the end of World War II. Treaty critics credit this extraordinary result to peace through strength, including the prospect of devastating, potentially genocidal threats, more politely known as nuclear deterrence. They are only half right. Nuclear arms racing without diplomacy increases insecurity. Arms build-ups and deterrence require reassurance to maintain the nuclear peace. Nuclear deterrence without arms control is like trying to construct a lasting, protective edifice with bricks but no mortar.
