Slate considers the doomsday device.

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 [doomsday] 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."
