One morning in the sombre atmosphere of the Cabinet War rooms, Churchill ordered his staff to "think the unthinkable". The result was Operation Unthinkable: a putative attack on Russia by a British and American army. Churchill's War Cabinet staff officers set to work.
Too long to quote all here I think. Not sure if they had correct information on the Soviet army but their conclusion was not to do it.
