This is a video about the son of a Hamas leader, Mosab Hassan Yousef, that helped the Israelis and eventually became a Christian when in the U.S.
Was nearly sent to his doom by U.S. authorities who initially refused to grant him asilym. His former Israeli secret service handler loved him so much, he risked his own life to come to the U.S. to go to bat for him.
I highly recommend it. Particularly for anti-Zionists that think they are doing otherwise than advancing terrorism, by aiding the so-called "Palestinians" in any way shape or form.
He wrote a book "Son of Hamas"
