Espionage Experts Say Israel Is a Major Collector of U.S. Intel

The arrest of a New Jersey engineer on charges of conspiracy to pass U.S. military secrets to Israel Tuesday shows a consistent, continued pattern of Israeli spying on its major benefactor, the United States, according to espionage experts.

"The Israelis have always been active intelligence collectors in the U.S. It's just a matter of time in terms of when we have sufficient evidence to bring one of the cases," said John Martin, retired senior U.S. Department of Justice executive who oversaw the investigation and prosecution of espionage cases in the U.S. for more than 30 years, including that of convicted spy Jonathan Pollard. Pollard is currently serving his 23rd year of a life sentence in federal prison in North Carolina for passing highly classified information to Israel.

"[The Israelis] got caught again, and they'll get caught again after this," said Martin, referring to Tuesday's indictment by the U.S. government of Ben-Ami Kadish, a former U.S. military engineer who allegedly helped give restricted nuclear weapons data, classified jet fighter weapons system data and key information on the Patriot missile system to Israel between 1979 and 1985. abcnews
