The Observer reports: Chilling new evidence that Britain and America came close to provoking the Soviet Union into launching a nuclear attack has emerged in former classified documents written at the height of the cold war.
Cabinet memos and briefing papers released under the Freedom of Information Act reveal that a major war games exercise, Operation Able Art, conducted in November 1983 by the US and its Nato allies was so realistic it made the Russians believe that a nuclear strike on its territory was a real possibility.
When intelligence filtered back to the Tory government on the Russians’ reaction to the exercise, the prime minister, Margaret Thatcher, ordered her officials to lobby the Americans to make sure that such a mistake could never happen again. Anti-nuclear proliferation campaigners have credited the move with changing how the UK and the US thought about their relationship with the Soviet Union and beginning a thaw in relations between east and west.
The papers were obtained by Peter Burt, director of the Nuclear Information Service (NIS), an organisation that campaigns against nuclear proliferation, who said that the documents showed just how risky the cold war became for both sides.
“These papers document a pivotal moment in modern history – the point at which an alarmed Thatcher government realised that the cold war had to be brought to an end and began the process of persuading its American allies likewise,” he said.
“The Cold War is sometimes described as a stable ‘balance of power’ between east and west, but the Able Archer story shows that it was in fact a shockingly dangerous period when the world came to the brink of a nuclear catastrophe on more than one occasion.”
Able Archer, which involved 40,000 US and Nato troops moving across western Europe, co-ordinated by encrypted communications systems, imagined a scenario in which Blue Forces (Nato) defended its allies after Orange Forces (Warsaw Pact countries) sent troops into Yugoslavia following political unrest. The Orange Forces had quickly followed this up with invasions of Finland, Norway and eventually Greece. As the conflict had intensified, a conventional war had escalated into one involving chemical and nuclear weapons.
Numerous UK air bases, including Greenham Common, Brize Norton and Mildenhall, were used in the exercise, much of which is still shrouded in secrecy. However, last month Paul Dibb, a former director of the Australian Joint Intelligence Organisation, suggested that the 1983 exercise posed a more substantial threat than the Cuban missile crisis of 1962. “Able Archer could have triggered the ultimate unintended catastrophe, and with prompt nuclear strike capacities on both the US and Soviet sides, orders of magnitude greater than in 1962,” he said.
