Netanyahu's IDF stuns U.S.? Israel accused of failing to protect American in West Bank blaze

A U.S. citizen, Khamis Ayyad, was killed in a suspected Israeli settler arson attack in the West Bank town of Silwad. This is the second American death linked to settler violence in July. The U.S. State Department has confirmed the incident and condemned the violence. Ayyad's family demands justice, while Israeli authorities investigate. What does this mean for U.S.-Israel relations?
