Operation Unthinkable: The Contingency Plan for War with the Soviet Union after World War II

TLDR Operation Unthinkable was a contingency plan developed by the British Chiefs of Staff Committee for a potential attack by the Soviet Union or a preemptive attack on the Soviets by a combined American and British force. However, the plan was ultimately ignored and never considered due to the lack of desire for another war and the Soviets' major advantage in terms of troops and armor.
