Mosab Hassan Yousef, son of one Hamas founder Hassan Yousef who in the past served as an undercover agent for the Israel Security Agency (Shin Bet), on Sunday told the Jerusalem Post conference in New York that “Islam is the problem” and that the free world must fight it.

Yousef, whose code name was “The Green Prince”, risked his life working undercover for the Shin Bet, and during that time he supplied information that prevented dozens of suicide attacks and assassinations of Israelis and exposed numerous Hamas terrorist cells.

He ultimately converted to Christianity and fled to the United States where he was granted political asylum.

“At one point I thought that the Jewish nation is the enemy of humanity. I thought they were the enemy of our people, the Palestinian people, until I experienced what the Jewish nation truly is,” said Yousef, who described Israel as “the only light in the Middle East”.

“We can fool ourselves, but there is an Islamic problem,” he continued, adding, “Al-Qaeda, Hamas, Hezbollah, the Islamic Jihad, the Islamic State (ISIS) and Boko Haram - all of them kill in the name of Allah.”

“There is an Islamic problem and humanity needs to stand against this danger, because it is not directed only against Israel. This danger is against human evolution,” warned Yousef.

“Humanity and the free world must unite. Today the free world should unite against Islam, not against Muslims but against Islam as a belief system. When the president of the free world says that Islam is a religion of peace, he creates the climate for the formation of more terror,” he added.

Yousef praised Israel for its morality and its values, saying Israel is a “nation that managed to survive the Holocaust and instead of assuming the role of victim and blaming everyone they were able to establish a democratic state - a young country which developed in less than 25 years. This is a good example for everyone.”
