Prior to Pollard's plea bargain, the U.S. government began preparing a multi-count criminal indictment against him, which included drug offences and tax fraud along with espionage. The government alleged that Pollard used classified documents to unsuccessfully broker an arms deal with the governments of South Africa, Argentina, and Taiwan. FBI investigators also determined that Pollard met with three Pakistanis and an Iranian foreigner in an attempt to broker arms in 1985. Pollard eventually cooperated with investigators in exchange for a plea agreement for leniency for himself and his wife. Israel said initially that Pollard worked for an unauthorized rogue operation, a position they maintained for more than ten years. They finally agreed to cooperate with the investigation in exchange for immunity for the Israelis involved.
