25 ViZionaries: Mosab Hassan Yousef - No.16

Mosab Hassan Yousef, dubbed the Green Prince, is the son of one of Hamas’s founders and leaders. He famously became a key informant for Israel’s Shin Bet (Israel Security Agency), providing vital intelligence for over a decade. His efforts helped thwart numerous terrorist attacks, by which he earned his notorious nickname.

Yousef later publicly renounced Hamas and moved to the United States, where he became a vocal advocate for peace and a critic of Islamic extremism. His story was chronicled in the award-winning documentary The Green Prince and his autobiography Son of Hamas.
