It was a common phrase of Brzezinski during the Cold War era to describe the Soviet Union (or East Block countries) as "Communist Experiments" (vs. USA as the Proto-Capitalist Experiment country). I'm not sure if he'd did that in the english version of his books though.
One of his German ones is called: "Das gescheiterte Experiment: Der Untergang des kommunistischen Systems" (The failed experiment: the fall of the communist system".
