Among the prominent speakers at the opening day of AIPAC's 2015 Policy Conference in Washington Monday was Mosab Hassan Yousef, son of one of the founders of the Hamas terrorist group whose work as a spy for Israel's intelligence agency earned him the codename "Green Prince."

Speaking to veteran Israeli journalist Avi Issacharov, Yousef explained his journey from a committed Islamist extremist to an equally committed supporter of Israel and convert to Christianity.

"I started to realize that we are living a lie, and people are dying because of this lie," he said in a brief introductory video to his speech.
