Able Archer and Grenada
On September 29, nearly a month after the KAL 007 tragedy, Andropov issued an official declaration to the Soviet people, stating that as long as Ronald Reagan occupied the Oval Office there could be no chance of negotiating with the United States. According to the general secretary, the United States was embarking on “a militarist course that represents a serious threat to peace.” Angry rhetoric between the United States and the USSR was nothing new, but never before had the leader of either superpower declared that he would not negotiate with the other.
On October 25, international tensions were ratcheted up further when the United States launched an invasion of the small Caribbean island of Grenada. The official purpose was to rescue 250 American students at St. George’s School of Medicine who were caught in the middle of a power struggle between two communist factions. It took little more than 48 hours for the American invasion force to overwhelm the 1,200-man Peoples’ Revolutionary Army and a 780-man Cuban contingent. The fighting, while brief, was fierce, with the Americans suffering 134 casualties to 500 Grenadan and Cuban losses. The invasion was the largest American military operation since Vietnam and the first time that a communist nation had been invaded since North Korea.
The invasion seemed to confirm in Andropov’s mind what he had most feared. He saw in Grenada an example of the American president’s willingness to use force. A week after the landings in Grenada, NATO commenced a 10-day exercise codenamed Able Archer 83. It involved most of Western Europe and was directed from Supreme Headquarters Allied Powers Europe (SHAPE) at Casteau, Belgium. Able Archer was a complex simulation of a hypothetical war with the Warsaw Pact that included a series of fictional military exercises escalating to the launch of nuclear weapons.
As Able Archer commenced, NATO vehicles rumbled throughout the West German countryside sending simulated radio reports about Soviet and East German forces crossing the border and invading the Federal Republic. SHAPE received these reports and relayed them to the various situation rooms, where NATO leaders analyzed and considered their reactions.
While Able Archer went through imaginary alert stages for the next several days, the center issued to its agents a checklist of specific events that would indicate that a nuclear attack was imminent. NATO leaders surmised that it would take 7 to 10 days for the United States to fully prepare for a nuclear war from the time such a decision was made. Five days into the Able Archer exercise, Moscow appeared to believe that actual preparations were being made for such a war.
The Soviets Prepare to Strike
On November 9, the seventh day of Able Archer, Western intelligence reported that pilots of the Soviet 4th Air Army had been placed on alert at their air bases in East Germany and Poland. The warplanes included Sukhoi Su-24 “Fencer” precision-strike bombers capable of delivering tactical nuclear weapons. Their two-man crews sat ready in their cockpits, waiting for the order to stand down or the order to take off and proceed to their designated targets in Western Europe. NATO intelligence also reported the movement of the Soviet Red Banner Fleet from its bases in the Baltic and the North Sea. Information was coming in that the Soviets were preparing their most powerful weapons, their 300 ICBMs (Intercontinental Ballistic Missiles) for immediate launch on Andropov’s order. The general secretary sent messages to his counterparts in the Warsaw Pact warning them of the high probability of war breaking out and ordered Soviet ballistic submarines at sea to go into firing positions off the coast of the United States.
As these reports filtered in to Western intelligence agencies, there initially was little alarm. Analysts and experts who examined the information simply could not believe that the Soviets seriously thought that NATO was preparing a nuclear first strike. At this point, the West did not have any real clue just how dangerous the situation had become. It would take the warnings of a double agent to finally get the West suitably alarmed.
Oleg Gordievsky came from a family of spies. His brother had joined the KGB in 1957, and his father had served in the KGB’s Stalinist predecessor, the NKVD. Gordievsky himself had joined in 1962. By 1983, he was a KGB colonel, serving in London as the resident delegate to the KGB mission, the highest ranking KGB officer in the United Kingdom. His decision to work for the other side came from his thorough disillusionment with Soviet communism. In 1974, while serving in the KGB mission in Copenhagen, Denmark, he started to actively cooperate with Great Britain’s MI6.
Gordievsky understood the depth of suspicion, paranoia, and downright panic that was seizing the Kremlin. As he received directives from Moscow about the imminence of a nuclear attack, he did not hesitate to inform his British handlers. “When I told the British,” he later recalled, “they simply could not believe that the Soviet leadership was so stupid and narrow-minded as to believe in something so impossible.” It was not until Gordievsky passed along the directives he had received that the British really started to pay attention. Copies of these directives made it into the hands of Prime Minister Margaret Thatcher, who forwarded the documents to the Central Intelligence Agency.
