Three weeks before Pollard's sentencing, Wolf Blitzer, at the time a "Jerusalem Post" correspondent, conducted a jail-cell interview with Pollard. The interview formed the basis of Blitzer's newspaper article, which also ran in "The Washington Post" on February 15, 1987, under the headline "Pollard: Not A Bumbler, but Israel's Master Spy". Pollard told Blitzer about some of the information he provided the Israelis: reconnaissance satellite photography of Palestine Liberation Organization (PLO) headquarters in Tunisia, which was used for Operation Wooden Leg; specific capabilities of Libya's air defenses; and "the pick of U.S. intelligence about Arab and Islamic conventional and unconventional military activity, from Morocco to Pakistan and every country in between. This included both 'friendly' and 'unfriendly' Arab countries." Prosecutor Joseph diGenova presented the Blitzer prison interview as evidence in his sentencing memorandum that Pollard had engaged in "unauthorized disclosure of classified information."
