Mosab Hassan Yousef, the son of Hamas co-founder Sheikh Hassan Yousef and a former Islamist militant turned Israeli intelligence asset, has issued a stark warning about the dangers of radicalization and what he describes as an escalating identity crisis within parts of the Muslim world.

Speaking with Piers Morgan, Yousef reflected on his personal journey from extremism to defection, describing the ideological grip of militant Islam and the severe consequences faced by those who challenge it. “They will kill me,” Yousef said, underscoring the risks he continues to face for speaking publicly against Islamist movements.

His comments come amid renewed global scrutiny of extremism following the deadly Bondi Beach attack, where investigators say antisemitic hatred and extremist ideology played a central role. While full details about the perpetrators are still emerging, authorities have emphasized that ideological radicalization remains a persistent threat.

Yousef argued that even if a Gaza ceasefire holds, extremism will continue to pose serious challenges, particularly as thousands of young people process grief, anger, and loss in conflict-affected communities. According to Yousef, these conditions create fertile ground for radical ideologies to spread.

Drawing on his unique perspective from inside Hamas, Yousef warned that militant groups exploit identity confusion, religious absolutism, and perceived victimhood to recruit and indoctrinate followers. He called for greater honesty in confronting the ideological roots of terrorism, stressing that security measures alone are insufficient without addressing radical beliefs.

Yousef’s testimony offers a rare insider account of Islamist extremism and highlights the long-term ideological struggle facing societies grappling with terrorism, antisemitism, and political violence.
