In late 1983, well before Mikhail Gorbachev’s elevation as General Secretary of the Communist Party, the Reagan administration switched gears in dealing with the Soviet Union, moving from a policy of confrontation to the alleviation of the Politburo’s deep anxieties. This was a tumultuous year in superpower relations, marked by the surprise unveiling of SDI, the deployment of “Euro-missiles,” the Soviet walk-out from nuclear negotiations in Geneva, the shoot-down of a Korean airliner that strayed over Soviet territory – a screw up that was characterized as a deliberate, malevolent act by senior Reagan administration officials – and extremely harsh, top-down rhetoric from both capitals.

During this perilous year, those with intelligence backgrounds in the Soviet Politburo, led by General Secretary Yuri Andropov, believed that the Reagan administration was willing and capable of carrying out a surprise attack. Andropov & Co. ordered Soviet agents to monitor U.S. blood banks and the number of lights on late at night in the State Department and Pentagon. The U.S. intelligence community, chastened by the “Team B” critique of its too-soft assessments of Soviet strategic goals, had officially come around to the view that the Kremlin was seeking to exploit its emerging strategic superiority. During most of the first three years of the Reagan administration, Washington and Moscow were like ships passing blindly in the night, both convinced that some sort of crash was imminent.

Why did the Reagan administration switch gears? Was this the result of a carefully planned presidential script, whereby the Reagan administration’s military build up served as the precursor to negotiated arms reductions? A new book by Martin and Annelise Anderson, Reagan’s Secret War (2009), argues this case: “With the benefit of hindsight, we see intent, planning, and timing.” Paul Lettow’s book, Ronald Reagan and his Quest to Abolish Nuclear Weapons (2005), makes a similar case. Or was this switch the result of a shifting balance of power among Reagan’s advisers, where deal-makers supplanted hard liners? Many first-person accounts of the Reagan years, as well as Strobe Talbott’s fine books, provide ample evidence for this thesis.

I believe there is a third explanation for the Reagan administration’s turn-around but, as yet, there is only indirect evidence for this hypothesis. Don Oberdorfer told some of this tale in The Turn (1991). Two months after KAL 007 was shot down, the United States and its NATO allies conducted a “nuclear release exercise” code-named Able Archer. The Andersons tell us that this exercise was carried out with “a bit more enthusiasm than usual.” Suffice it to say that Able Archer gave paranoids in the Politburo added reason to observe the night shift at the Pentagon. David Hoffman’s new book, The Dead Hand: The Untold Story of the Cold War Arms Race and Its Dangerous Legacy (2009), adds further detail to this hair-raising story.

During this time, British intelligence was handling a Soviet double agent, Oleg Gordievsky (pictured above, with Reagan), then stationed in London. “On the night of November 8-9,” Oberdorfer writes, “according to Gordievsky, Moscow sent flash telegrams to its KGB stations in Western Europe to gather all possible information on the highest priority basis of U.S. preparations for a surprise missile attack against the Soviet Union.” This information was passed along to the CIA “within weeks after the end of Able Archer.” Hoffman’s reporting suggests that Gordievsky’s alarming information was conveyed before Able Archer, as well. When did this information reach President Reagan?

Now back to the Andersons. They point to a key entry in Ronald Reagan’s diary, dated November 18, 1983:

I feel the Soviets are so defense-minded, so paranoid about being attacked, that without being in any way soft on them, we ought to tell them no one here has any intention of doing anything like that.

Reagan then began working more intensively with Secretary of State George Shultz to lay the groundwork for reassuring the Kremlin and re-starting negotiations.

The Andersons mention Gordievsky on the page after quoting this diary excerpt, but not as the source of Reagan’s disquiet. My sense is that Gordievsky played a crucial role in the turnaround from confrontation to negotiation by de-clawing the Team B approach to the Kremlin, reaffirming in Reagan’s mind the need to act to avoid Armageddon, and empowering the deal makers around the President.

Is Gordievsky one of the unsung heroes of the Cold War? More supportive evidence is needed.
