Apparently Perimeter was installed to soothe jittery, trigger-happy Soviet military men, but it's making me uncomfortable - after all, it's still running, long after the Cold War ended!:
Yarynich is talking about Russia's doomsday machine. That's right, an actual doomsday device—a real, functioning version of the ultimate weapon, always presumed to exist only as a fantasy of apocalypse-obsessed science fiction writers and paranoid über-hawks. The thing that historian Lewis Mumford called "the central symbol of this scientifically organized nightmare of mass extermination." Turns out Yarynich, a 30-year veteran of the Soviet Strategic Rocket Forces and Soviet General Staff, helped build one.
The point of the system, he explains, was to guarantee an automatic Soviet response to an American nuclear strike. Even if the US crippled the USSR with a surprise attack, the Soviets could still hit back. It wouldn't matter if the US blew up the Kremlin, took out the defense ministry, severed the communications network, and killed everyone with stars on their shoulders. Ground-based sensors would detect that a devastating blow had been struck and a counterattack would be launched.
The technical name was Perimeter, but some called it Mertvaya Ruka, or Dead Hand.
...The system that Yarynich helped build came online in 1985, after some of the most dangerous years of the Cold War. Throughout the '70s, the USSR had steadily narrowed the long US lead in nuclear firepower. At the same time, post-Vietnam, recession-era America seemed weak and confused. Then in strode Ronald Reagan, promising that the days of retreat were over. It was morning in America, he said, and twilight in the Soviet Union.
Part of the new president's hard-line approach was to make the Soviets believe that the US was unafraid of nuclear war. Many of his advisers had long advocated modeling and actively planning for nuclear combat. These were the progeny of Herman Kahn, author of On Thermonuclear War and Thinking About the Unthinkable. They believed that the side with the largest arsenal and an expressed readiness to use it would gain leverage during every crisis.
The new administration began expanding the US nuclear arsenal and priming the silos. And it backed up the bombs with bluster. In his 1981 Senate confirmation hearings, Eugene Rostow, incoming head of the Arms Control and Disarmament Agency, signaled that the US just might be crazy enough to use its weapons, declaring that Japan "not only survived but flourished after the nuclear attack" of 1945. Speaking of a possible US-Soviet exchange, he said, "Some estimates predict that there would be 10 million casualties on one side and 100 million on another. But that is not the whole of the population."
...The strategy worked. Moscow soon believed the new US leadership really was ready to fight a nuclear war. But the Soviets also became convinced that the US was now willing to start a nuclear war. "The policy of the Reagan administration has to be seen as adventurous and serving the goal of world domination," Soviet marshal Nikolai Ogarkov told a gathering of the Warsaw Pact chiefs of staff in September 1982. "In 1941, too, there were many among us who warned against war and many who did not believe a war was coming," Ogarkov said, referring to the German invasion of his country. "Thus, the situation is not only very serious but also very dangerous."
A few months later, Reagan made one of the most provocative moves of the Cold War. He announced that the US was going to develop a shield of lasers and nuclear weapons in space to defend against Soviet warheads. He called it missile defense; critics mocked it as "Star Wars."
To Moscow it was the Death Star—and it confirmed that the US was planning an attack. It would be impossible for the system to stop thousands of incoming Soviet missiles at once, so missile defense made sense only as a way of mopping up after an initial US strike. The US would first fire its thousands of weapons at Soviet cities and missile silos. Some Soviet weapons would survive for a retaliatory launch, but Reagan's shield could block many of those. Thus, Star Wars would nullify the long-standing doctrine of mutually assured destruction, the principle that neither side would ever start a nuclear war since neither could survive a counterattack.
As we know now, Reagan was not planning a first strike. According to his private diaries and personal letters, he genuinely believed he was bringing about lasting peace. (He once told Gorbachev he might be a reincarnation of the human who invented the first shield.) The system, Reagan insisted, was purely defensive. But as the Soviets knew, if the Americans were mobilizing for attack, that's exactly what you'd expect them to say. And according to Cold War logic, if you think the other side is about to launch, you should do one of two things: Either launch first or convince the enemy that you can strike back even if you're dead.
Perimeter ensures the ability to strike back, but it's no hair-trigger device. It was designed to lie semi-dormant until switched on by a high official in a crisis. Then it would begin monitoring a network of seismic, radiation, and air pressure sensors for signs of nuclear explosions. Before launching any retaliatory strike, the system had to check off four if/then propositions: If it was turned on, then it would try to determine that a nuclear weapon had hit Soviet soil. If it seemed that one had, the system would check to see if any communication links to the war room of the Soviet General Staff remained. If they did, and if some amount of time—likely ranging from 15 minutes to an hour—passed without further indications of attack, the machine would assume officials were still living who could order the counterattack and shut down. But if the line to the General Staff went dead, then Perimeter would infer that apocalypse had arrived. It would immediately transfer launch authority to whoever was manning the system at that moment deep inside a protected bunker—bypassing layers and layers of normal command authority. At that point, the ability to destroy the world would fall to whoever was on duty: maybe a high minister sent in during the crisis, maybe a 25-year-old junior officer fresh out of military academy. And if that person decided to press the button ... If/then. If/then. If/then. If/then.
Once initiated, the counterattack would be controlled by so-called command missiles. Hidden in hardened silos designed to withstand the massive blast and electromagnetic pulses of a nuclear explosion, these missiles would launch first and then radio down coded orders to whatever Soviet weapons had survived the first strike. At that point, the machines will have taken over the war. Soaring over the smoldering, radioactive ruins of the motherland, and with all ground communications destroyed, the command missiles would lead the destruction of the US.
...So why was the US not informed about Perimeter? Kremlinologists have long noted the Soviet military's extreme penchant for secrecy, but surely that couldn't fully explain what appears to be a self-defeating strategic error of extraordinary magnitude.
The silence can be attributed partly to fears that the US would figure out how to disable the system. But the principal reason is more complicated and surprising. According to both Yarynich and Zheleznyakov, Perimeter was never meant as a traditional doomsday machine. The Soviets had taken game theory one step further than Kubrick, Szilard, and everyone else: They built a system to deter themselves.
By guaranteeing that Moscow could hit back, Perimeter was actually designed to keep an overeager Soviet military or civilian leader from launching prematurely during a crisis. The point, Zheleznyakov says, was "to cool down all these hotheads and extremists. No matter what was going to happen, there still would be revenge. Those who attack us will be punished."
And Perimeter bought the Soviets time. After the US installed deadly accurate Pershing II missiles on German bases in December 1983, Kremlin military planners assumed they would have only 10 to 15 minutes from the moment radar picked up an attack until impact. Given the paranoia of the era, it is not unimaginable that a malfunctioning radar, a flock of geese that looked like an incoming warhead, or a misinterpreted American war exercise could have triggered a catastrophe. Indeed, all these events actually occurred at some point. If they had happened at the same time, Armageddon might have ensued.
Perimeter solved that problem. If Soviet radar picked up an ominous but ambiguous signal, the leaders could turn on Perimeter and wait. If it turned out to be geese, they could relax and Perimeter would stand down. Confirming actual detonations on Soviet soil is far easier than confirming distant launches. "That is why we have the system," Yarynich says. "To avoid a tragic mistake. "
The mistake that both Yarynich and his counterpart in the United States, Bruce Blair, want to avoid now is silence. It's long past time for the world to come to grips with Perimeter, they argue. The system may no longer be a central element of Russian strategy—US-based Russian arms expert Pavel Podvig calls it now "just another cog in the machine"—but Dead Hand is still armed.
