The son of Hamas’s co-founder delivered a chilling warning about New York City’s socialist mayor-elect, describing Zohran Mamdani as a catastrophic figure who will “only succeed in one thing — burning the castle down” by functioning as a “Trojan horse” for what he identified as the Red-Green Alliance — a coordinated effort between radical communist and Islamist forces seeking to dismantle Western capitalism and fundamentally transform America’s largest city.
