Former US Navy Petty Officer Ronald Pollard was recruited by Israeli intelligence forces to spy against the United States on behalf of Israel. Pollard provided sensitive intelligence to Israel, was tried and convicted of espionage, and is currently serving a life sentence. Israel regards Pollard as a hero and a patriot. Israel has repeatedly sought Pollard's release on humanitarian grounds and/or as part of broader multilateral agreements.
Granting Pollard parole would be an insult to those US Military, Diplomatic, Intelligence and other personnel who, entrusted with sensitive information, did NOT betray that trust by committing espionage.
