In the context of the Second World War, what was ‘Operation Unthinkable’?
Answer: The code name for two plans involving conflict between the Western Allies and the Soviet Union in 1945. The Soviet Union had been allies of the West during World War Two. The first involved an Allied surprise attack on Soviet Union forces in East Germany, while the second was a defensive plan if the Soviets themselves attacked Allied positions. Highly secretive, the plans were not made public until 1998.
