"According to CIA sources, Pollard provided Israeli intelligence with names of important American agents inside the former Soviet Union and Russia who had supplied information on East Bloc weapons and war plans. How the agent's names were linked to the secrets they supplied - a major breach of basic intelligence security - remains a major mystery. Some of the enormously sensitive secrets stolen by Pollard were reportedly either sold, or bartered, by Israel to the Soviet Union.
"A number of key CIA agents in the East Bloc were reportedly executed as a result of Pollard spying. KGB likely gained access to top-secret US codes - either directly from Israel, or through spies in Israel's government. In short, Pollard's treachery caused one of the worst security disasters in modern American history.
"FBI investigators discovered Pollard was being directed to steal specific secret data by a senior Administration official, known as "Mr. X." But the White House, unwilling to stir up a domestic political storm, quashed the investigation. To my knowledge, three previous cases of high-ranking US government officials caught passing top secret information to Israel have been similarly hushed up. Two were senior defense department officials under Reagan, one a top State Department official in a previous administration. None were prosecuted."
