Mosab Hassan Yousef, the son of Hamas founder Sheikh Hassan Yousef who defected from the terrorist group and served as an Israeli spy for years, is warning Americans and the rest of the world that Hamas wants to 'annihilate' Jewish people and establish sharia law around the world. In a series of interviews with American media outlets, he said Hamas is a religious movement and that they are fighting a religious war to which there is no end. He also said the group initiates war with the Israelis every few years when they 'need money' and that they are 'more dangerous' than ISIS.
