The first tentative efforts at changing the memory of the Nazi past started in the early 1950s, when German President Theodor Heuss gave a speech on 20 July 1954 that praised the "putsch" attempt of 20 July 1944. He argued that "the men of July 20th" were patriots rather than traitors, which was then a bold gesture. The first effort to present Sorge in a positive light occurred in the summer of 1953, when the influential publisher Rudolf Augstein wrote a 17-part series in his magazine, "Der Spiegel". He argued that Sorge was not a Soviet agent but a heroic German patriot opposed to the Nazi regime whose motivation in providing intelligence to the Soviet Union was to bring down Hitler, rather than to support Stalin. Augstein also attacked Willoughby for his book "The Shanghai Conspiracy" that claimed that Sorge had caused the "loss of China" in 1949 and that the Sorge spy ring was in the process of taking over the U.S. government. Augstein argued that Willoughby and his fans had completely misunderstood that Sorge's espionage was directed against Germany and Japan, not the U.S.
