Did the Russians actually build a "doomsday machine?" (And is it still "ticking?")

This article's from last summer, and I came across it while researching something else...

Did the Soviets actually design a variation on a doomsday device and not tell us about it? And could an accidental or terrorist nuclear attack on Putin's Russia (by Chechens, for instance) trigger an antiquated automated dead-hand system and launch missiles capable of killing tens, maybe hundreds, of millions at unknown targets that might include the United States?

Up until Aug. 10 of this year, I would have thought these questions were best consigned to the realm of apocalyptic film fantasy. But on that day I came upon a startling essay in the London Times Literary Supplement. It was a review (titled "Deadly Devices") of a book recently published in the United Kingdom: Doomsday Men: The Real Dr. Strangelove and the Dream of the Superweapon by nuclear-age historian P.D. Smith of University College London. (It will be out in the United States in December.)

The TLS reviewer, Christopher Coker (who is on the faculty of the London School of Economics), asserted that the book demonstrates that "only after the Berlin Wall had been breached and ... the Cold War began to thaw did military analysts realize the Russians had actually built a version of the device. The details of this top-secret Soviet system were first revealed in 1993 by Bruce G. Blair, a former American ICBM launch control officer, now one of the country's foremost experts on Russian arms. Fearing that a sneak attack by American submarine-launched missiles might take Moscow out in 13 minutes, the Soviet leadership had authorized the construction of an automated communication network, reinforced to withstand a nuclear strike. At its heart was a computer system similar to the one in Dr. Strangelove. Its code name was Perimetr. It went fully operational in January 1985. It is still in place."

Wait a minute. Still in place?! How is this possible?

Blair's primary recent concern is not the prospect of a deliberate, ideological, Cold War-type nuclear war, but accidental war caused by the continued deadly presence of all-too-easily triggered Cold War arsenals. In four fascinating papers on the subject (all available online, and well worth reading), Blair describes the "launch on warning" bias built into our nuclear command structure, and foresees the possibility of a doomsday that results from our attempt to pre-empt their doomsday plan, all of which might be touched off by accident, mistake, or malfunction on either side.

Blair is not a wild-eyed Cassandra raising unsupported suspicions. Colleagues in his field regard him as a serious and cautious scholar raising real questions. Stephen M. Meyer, an expert on the Russian military at MIT, told the Times that Blair "requires of himself a much higher standard of evidence than many people in the intelligence community."
