The prosecutors in the internal-security cases of the 1940s did not know they had not been given all, or even the best government evidence, against the Rosenbergs, and others. The Venona project materials would have been conclusive in establishing the cast of characters in the Soviet spy networks. Government secrecy allowed critics of the Rosenberg and Hiss cases to construct elaborate theories about frame-ups and cover-ups. For years the Rosenbergs' defenders demanded that the government reveal its secrets about the case. When Secrecy Commission forced the disclosure of documents, the secrets revealed the government's case was even stronger. "Over the years," said Ronald Radosh, "the Rosenbergs' defenders have loudly demanded the release of government documents on the case, only to deny the documents' significance once they are made public." As archives of the Cold War are opened, the original case made against Soviet espionage in the United States has received ever more conclusive corroboration.
