In a quiet room at Israel’s soon-to-be inaugurated October 7 Museum, Mosab Hassan Yousef—the son of Hamas co-founder Sheikh Hassan Yousef who is also known as “The Green Prince”—looked at the evidence of Hamas’s atrocities and spoke the truth that too many still refuse to hear: “Hamas is not just at war with Israel. It is at war with Jews, Christians and the very foundations of civilization itself.”

Yousef knows this from the inside. Raised in a home steeped in Hamas ideology, he was taught from childhood that Jews must be killed, Christians eliminated, and “infidels” subjugated. He was beaten at school, indoctrinated on the streets, and expected to take his place in a cult of death. Instead, he broke free, worked with Israeli intelligence to prevent countless terror attacks, and later embraced Christianity. His father disowned him and sentenced him to death.

Religious war

His visit to the new museum, which is in Glilot in central Israel, was organized by Dan Diker, president of the Jerusalem Center for Security and Foreign Affairs.

When Yousef looks at Hamas’s hand-written instructions for Oct. 7, 2023—orders to rape women, burn babies alive and kidnap hundreds—he doesn’t see aberrations. He sees what he says is the logical outcome of Hamas’s creed. “This is not politics,” he told us. “This is a religious war. Its purpose is to replace Judaism and Christianity with radical Islam. If the world does not understand this, everyone will pay the price.”

He is right. The “Al-Aqsa Flood,” as Hamas named its Oct. 7 attacks, was not about borders or blockades. It was framed explicitly as a religious conquest, part of a centuries-old war of replacement. In Hamas’s view, Judaism and Christianity are illegitimate faiths that must yield to Islam.

That is why Hamas teaches Palestinian children to glorify death, publishes math textbooks where subtraction problems involve dead Jews, and hands out Hitler’s Mein Kampf alongside the Quran in Gaza schools.
