Stalin's “last word” on German reunification was contained in the Soviet diplomatic note of March 10, 1952, which proposed a peace treaty with Germany. Until the middle of 1953, Stalin's heirs continued to press for reunification on the basis of the 1952 note. The East German uprising of June 17, 1953 (which is commemorated in West Germany, with unintended irony, as the “Day of German Unity“) marked the de facto termination of the Soviet reunification initiative. As a result of the uprising, the rulers of the Soviet Union and East Germany were forced to place greater emphasis on the consolidation of the Communist regime in the GDR—that is, the stability of East Germany required policies explicitly directed toward the development of a separate, socialist East German state. Thus, the uprising and the subsequent Soviet intervention further undermined the credibility of an already questionable Soviet reunification initiative.
