Yeah the guy who devised Project Unthinkable
Beyond that, the Soviets knew about it before the ink was dry. Marshal Zhukov started moving his forces around in Poland and Germany in June 1945. So, to recap, the Russians already taken action against Operation Unthinkable before it was even past the drawing board. So, it's safe to call it a colossal failure.
The U.K. was so riddled with Soviet spies then, that Stalin knew when Churchill sneezed, before Churchill did.
