The most worrisome problem posed by hostile states—Islamic or otherwise—is the mental state of their leaders and the fear that deterrence may not work against millenarian zealots. During the Cold War the Soviet leaders were, in the main, rational calculators. While ruthless adversaries, they were acutely cognizant of the potential consequences of starting a nuclear war. Even Joseph Stalin, paranoid mass murderer of tens of millions, confined his strategic goal to victory without fighting a war.
Later Soviet leaders were similarly deterred. Leonid Brezhnev seriously considered a preemptive nuclear strike against China in 1969, when the two countries engaged in a series of bloody clashes along their Ussuri River border. At the time Russia’s arsenal vastly exceeded that of China, whose nascent program had produced perhaps 25 to 40 bombs. But Brezhnev decided to pass. Had Brezhnev struck China first, his chance to get a strategic arms pact with America would have evaporated. America’s immense arsenal troubled him more than China’s relatively puny one at the time.[18]
Once indeed the world did come to the very brink of a shooting nuclear war, during the Cuban Missile Crisis. Let us return to 1962, and see what context this story can give us to apply to Iran today. That August, U.S. reconnaissance planes discovered that Russian construction teams were placing intermediate-range ballistic missiles at bases in the Cuban countryside. In response, the Kennedy administration imposed a naval “quarantine” (blockading contraband supplies only) around the island.
On October 15, Kennedy convened an executive committee of 13 “wise men” to suggest ways to resolve the crisis. Their firmly shared belief was that it was unacceptable to have Russian missiles armed with nuclear warheads sitting 90 miles south of Florida. One of them, Paul Nitze, wrote later that at the outset nearly all “ExComm” members—including the president and his brother Robert—believed that military action to remove the missiles was almost inevitable. In his Cuban Missile Crisis history, Nine Minutes to Midnight, Michael Dobbs superbly described what happened next.
On October 27, which the White House dubbed “Black Saturday,” things nearly spun out of control. A U.S. U-2 spy plane was downed and its space-suited pilot killed, by a Soviet surface-to-air missile at Castro’s orders. Another U-2 pilot on an Arctic surveillance mission was tricked by an intense aurora borealis (“Northern Lights”) into taking a wrong turn, penetrating 300 miles into Soviet airspace. That spy plane eluded Russian interceptors and by a major miracle made it back to friendly territory. This was not a true fail-safe scenario (inability to recall in time a hostile plane carrying bombs), as the plane was unarmed, but a shoot down would hardly have helped resolve the crisis.
Meanwhile, a U.S. destroyer was dropping depth charges to force a quarantine-breaking Russian diesel submarine to surface. Unbeknownst to the destroyer crew, the sub was armed with a 10-kiloton nuclear-tipped torpedo, some 70 percent as powerful as the Hiroshima bomb. Its commander was under strict orders not to fire a nuclear device without direct authorization from Moscow, but only by surfacing could the sub exchange messages with the authorities. But after being tracked by U.S. ships continuously—and being forced to stay below despite tropical conditions inside the sub—the Soviet commander was ready to fire his nuclear torpedo. His crew prevailed upon him to surface instead, noting the lack of authorization from Moscow. The sub surfaced to find itself in the midst of four U.S. destroyers. Moscow ordered the sub to depart the area, and the U.S. did not try to stop its departure. Had the submarine commander used his nuclear torpedo in 1962, it is inconceivable that Kennedy would have responded with an all-out attack over the loss of one of four small ships. It is hard to credit assertions that the USSR would have chosen mutual annihilation either.
Unknown to Kennedy and his advisers then was how many nuclear warheads and types of nuclear-capable delivery systems were on the island, or what command and control arrangements were in place between the Soviet and Cuban strategic forces. Dobbs writes (surely accurately) that Cuba’s nuclear arsenal “far exceeded the worst nightmares of anyone in Washington.” Specifically, deployed or en route to Cuba by ship were no less than 158 warheads. Ninety were already on the island, including 36 one-megaton warheads that could be hurled almost 1,300 miles and 36 14-kiloton warheads (Hiroshima-size) mounted on small tactical nuclear missiles. An estimated 150,000 American troops were to be sent to take the island, and 1,397 separate targets had been marked for destruction as part of the invasion. The Russians were prepared to send tactical bombers carrying Hiroshima-size A-bombs to annihilate any major invasion force.
Even without nuclear missile strikes on American soil, the instant carnage that would have been inflicted by the invasion force alone—by some 45,000 Soviets armed with atomic weapons, plus a much larger volunteer Cuban contingent—would have been the worst in American military history. The invasion force had the potential to suffer in a single day the death toll of Americans killed by enemy fire in the Korean and Vietnam wars combined.
En route on ships were 68 warheads, including two dozen for ballistic missiles, which could deliver one megaton 2,800 miles away (roughly the distance from Havana to Seattle). Khrushchev recalled these to Russia—weapon security on Cuba was dicey. The island heat made storage hotter than was safe for the warheads; accidental megaton-level ground detonation was a serious possibility. Without trigger locks, most nuclear weapons on Cuba could be released by the local commander—in some cases, a lieutenant—ignoring orders to the contrary from Moscow. Had an invasion come, as one Russian former soldier stationed in Cuba then put it, “You have to understand the psychology of the military person. If you are being attacked, why shouldn’t you reciprocate?” Ironically, the minimal level of perimeter and site security at the Bejucal nuclear storage bunker led CIA analysts to conclude that the facility did not house nuclear weapons.
Things were better, but far from secure, on the U.S. side. Pilots had unilateral release discretion for nuclear-armed air-to-air missiles, designed to vaporize strategic bomber squadrons. During the course of the 1950s and 1960s, several nuclear-armed strategic bombers crashed. One was carrying a pair of hydrogen bombs, each able to wipe out a major city. A crash cannot detonate a modern nuclear bomb, but such events are extremely dangerous nonetheless, in that any explosion can scatter highly radioactive nuclear material.
America’s fighter jets also could carry nuclear bombs. A nuclear-armed F-106 interceptor, armed with the MB-1 Genie air-to-air missile (a one-kiloton device that could be armed and fired at the pilot’s sole discretion), had a near mishap taking off. Designed to destroy all enemy planes within a quarter-mile radius, it was called by one pilot “the dumbest weapons system ever purchased.” F-102 interceptors had similar armament, and F-100 Super Sabres based in Europe carried hydrogen bombs to drop inside Russia. A young Navy pilot named John McCain sat in his A-4D Skyhawk jet on the aircraft carrier Enterprise, awaiting orders to drop A-bombs on selected Cuban targets.
Slow communications made matters worse. Both sides sent signals over broadcast television, sacrificing privacy for celerity. The Russian ambassador in Washington sent telegrams via Western Union, complete with pick-up via bicycle messenger. Informed by this potentially catastrophic infirmity, the superpowers established the Washington-Moscow Hot Line in 1963.

Late in the Cold War similar fears arose inside the Kremlin, though they were without foundation in fact. In 1983, Brezhnev’s successor, Yuri Andropov, reportedly feared a first nuclear strike from the planned NATO deployment of 108 Pershing II missiles, which could span the 1,000 miles from their Western European bases to Moscow within eight minutes and with great accuracy. One possible set of targets was command centers in Moscow. Andropov considered but ultimately declined to launch a preemptive nuclear attack on America. At that time, Fidel Castro reportedly asked—as he had during the 1962 Cuban Missile crisis—that the Soviets launch an all-out strike at the United States. Adrian Danilevitch, a former top Soviet war planner, described how Moscow “had to actively disabuse him of this view by spelling out the ecological consequences for Cuba (in a nutshell, it would disappear) of a Soviet strike against the U.S.” Castro’s request went nowhere.
