Weekend Interview with Mosab Hassan Yousef: 'They Need to Be Liberated From Their God'

"Now 32, Mosab is the son of Sheikh Hassan Yousef, a founder and leader of the Palestinian terrorist group Hamas. Throughout the last decade, from the second Intifada to the current stalemate, he worked alongside his father in the West Bank. During that time the younger Mr. Yousef also secretly embraced Christianity. And as he reveals in his book "Son of Hamas," out this week, he became one of the top spies for Israel's internal security arm, the Shin Bet."
