In 1952, the Stalin Note, as it became known, "caught everybody in the West by surprise". It offered to unify the two German entities into a single, neutral state with its own, non-aligned national army to effect superpower disengagement from Central Europe. Adenauer and his cabinet were unanimous in their rejection of the Stalin overture; they shared the Western Allies' suspicion about the genuineness of that offer and supported the Allies in their cautious replies. In this, they were supported by leader of the opposition Kurt Schumacher (a very rare occurrence), and recent (21st century) findings of historical research. Adenauer's flat rejection was, however, still out of step with public opinion; he then realized his mistake and he started to ask questions. Critics denounced him for having missed an opportunity for German reunification. The Soviets sent a second note, courteous in tone. Adenauer by then understood that "all opportunity for initiative had passed out of his hands," and the matter was put to rest by the Allies. Given the realities of the Cold War, German reunification and recovery of lost territories in the east were not realistic goals as both of Stalin's notes specified the retention of the existing "Potsdam"-decreed boundaries of Germany.
