STUNNING COLD WAR ADMISSION: In 1983 ‘war scare,’ Soviet leadership feared nuclear surprise attack by U.S.

A nuclear weapons command exercise by NATO in November 1983 prompted fear in the leadership of the Soviet Union that the maneuvers were a cover for a nuclear surprise attack by the United States, triggering a series of unparalleled Soviet military re­sponses, according to a top-secret U.S. intelligence review that has just been declassified.“In 1983, we may have inadvertently placed our relations with the Soviet Union on a hair trigger,” the review concluded.

The review concluded that for Soviet leaders, the war scare was real, and that U.S. intelligence post­mortems did not take it seriously enough.

Soviet leaders were particularly alarmed about the NATO exercise, known as Able Archer, carried out in early November 1983 involving forces­ that stretched from Turkey to Britain. Conducted annually to practice the procedures involved in the run-up to a nuclear conflict, the exercise had some new wrinkles that year, including planes that taxied out of hangars carrying realistic-looking dummy warheads, the review said.

The 109-page document, titled “The Soviet ‘War Scare,’ ” was dated Feb. 15, 1990, and written for the President’s Foreign Intelligence Advisory Board, a White House unit that examined intelligence issues. The authors of the review scrutinized classified documents and conducted 75 interviews with U.S. and British officials.

Originally stamped “Top Secret” and containing sensitive signals intelligence, the review was declassified this month in response to a request from the National Security Archive, a non­governmental organization affiliated with George Washington University.

The PFIAB review found that the Soviet Union took unusual military and intelligence precautions at the time of Able Archer that previously had been employed only in actual crises. This included placing air forces­ in East Germany and Poland on higher alert, conducting significantly more reconnaissance flights, and tasking Soviet KGB and military intelligence officers around the world to be on the lookout for signs of nuclear war preparations.

The Soviet actions “strongly” suggest that “Soviet military leaders may have been seriously concerned that the US would use Able Archer 83 as a cover for launching a real attack,” the review concluded. It added that the evidence “strongly indicates that the war scare was real, at least in the minds of some Soviet leaders.”

Some details of the Soviet paranoia about a nuclear attack had come to light earlier, including reports from Oleg Gordievsky, a KGB officer who was an agent for British intelligence. Gordievsky revealed to the British the existence of a KGB intelligence-collection effort to detect indications that the West was preparing for nuclear war. Gordievsky, who defected to Britain in 1985, later published the text of some KGB directives, part of a program known as ­RYAN or ­VRYAN, the acronyms in Russian for sudden nuclear missile attack.

Andropov’s worries

Yuri Andropov, the KGB chief who later became Soviet leader, was a major source of the anxiety in Moscow about a surprise nuclear attack. In 1981, Andropov declared to a major KGB conference that the Reagan administration was actively preparing for war and that a nuclear first strike was possible. According to the review, Andropov put “strategic military intelligence” at the top of KGB collection priorities, and he hastily created a special “institute” within the KGB in 1981 to handle it.

His worries about a surprise attack were amplified by “one peculiar mode of intelligence analysis,” a KGB computer model to measure perceived changes­ in the “correlation of ­forces” between the super­powers, according to the review. The computer went online in 1979 to warn Soviet leaders when “deterioration of Soviet power might tempt a US first strike,” the review says. The computer was at the heart of the ­VRYAN system, according to the review, and thousands of pieces of security and economic data were fed into the machine. The computer model assigned a fixed value of 100 to the United States, and Soviet leaders felt they would be safe from a nuclear first strike as long as they were at least at 60 percent of the United States, and ideally at 70 percent. Reports were sent to the ruling Politburo once a month.

Soon, the computer model produced bad news. According to the review, it calculated that Soviet power had declined to 45 percent; it was felt that below 40, the Soviet Union would be “dangerously inferior.” Although “it may seem absurd” to think the Soviet leaders would put stock in such a computer model, the review concluded, “this approach may have been especially appealing to top Soviet leaders at the time” because they craved some kind of scientific evidence of the strategic balance.

By 1983, Andropov had become Soviet leader, succeeding Leonid Brezhnev, and super­power tensions were deepening. According to the review, in January 1983, the Soviet armed forces­ added a fifth level of readiness to the existing four: “Surprise Enemy Attack Using Weapons of Mass Destruction in Progress.” This fifth condition “could be declared regardless of the readiness stage in effect at the time,” the review said.

On March 8, 1983, President Ronald Reagan called the Soviet Union an “evil empire.” By late that summer, the Soviet leadership “appeared to be bracing the population for the worst.” Signs were posted everywhere showing the location of air raid shelters; broadcasts suggesting the possibility of a U.S. attack were on radio and television “several times a day,” the review says.

Soviet spokesmen accused Reagan and his advisers of “madness,” “extremism” and “criminality.” After the Korean airliner was downed, tensions grew over NATO plans to deploy the Pershing II and ground-launched cruise missiles in Europe. Near the end of 1983, the 4th Air Army, a Soviet air force unit in Poland, received orders to speed up the transfer of nuclear weapons from storage to the aircraft, with a maximum time of 25 minutes for one weapon, 40 minutes for two, according to the review.

Meanwhile, Andropov, the Soviet leader, had become gravely ill.

New procedures in 1983

Able Archer was conducted every year and “routinely monitored by Soviet intelligence.” But the November 1983 version had new procedures “which we believe probably fueled Soviet anxieties,” the review found. NATO tested new communications methods, with a more graduated escalation. The Able Archer exercise also used live mobilization exercises from U.S. military forces­ in Europe, the review said. All this may have looked more realistic to Soviet spies, who were watching. Both the KGB and Soviet military intelligence were ordered on Nov. 8 or 9 to report on increased alert at U.S. bases in Europe and to check for other indications of an impending
