The Mossad's been getting beat up these past few days but this is pretty astounding:
The son of one of Hamasâ??s founding members was a spy in the service of Israel for more than a decade, helping prevent dozens of Islamist suicide bombers from finding their targets, it emerged today.Codenamed the Green Prince by Shin Bet, Israelâ??s internal security service, Mosab Hassan Yousef, the son of Hamas co-founder Sheikh Hassan Yousef, supplied key intelligence on an almost daily basis from 1996 onwards and tracked down suicide bombers and their handlers from his fatherâ??s organization, the daily Haaretz said.
There was a piece in the Atlantic a while back on British efforts to penetrate the IRA that had similar high-level double agents.
