In 1945, on VE Day, as Europe celebrated peace at the end of six years of war, Winston Churchill was brooding on the certainty that the celebrations would soon be brutally interrupted.
Operation Unthinkable had been authorised, and would soon shatter the empheral peace on the continent.
UnthinkableOperation Unthinkable was a plan ordered by British Prime Minister Winston Churchill and developed by the British Armed Forces at the end of World War II.
The primary goal of the operation was declared as follows: "to impose upon Russia the will of the United States and the British Empire". (The word "Russia" is used heavily throughout the document, although at the time the name Russia had been replaced by the "Soviet Union".)
The Chiefs of Staff were rightly concerned that given the enormous size of Soviet forces deployed in Europe at the end of the war, and the fact that the Soviet leader Joseph Stalin was unreliable, there existed a Soviet threat to Western Europe.
"to impose upon Russia the will of the United States and the British Empire".Churchill stated within the briefing documents for Unthinkable that it was a "precautionary study" of what he hoped was a "purely hypothetical contingency ".
The majority of the operation would have consisted of American and British forces, but it also contemplated the use of Polish forces and up to 100,000 surrendered German soldiers. The plan was approved by the British Chiefs of Staff Committee as militarily feasible in late April 1945.
