The conflict between Israel and Hamas has sent security services across the world into a panic over the potential for Islamist extremist attacks linked to the war. Already, lone actors in Belgium, Egypt and France have carried out lethal attacks, while affiliates of al Qaeda and the Islamic State have encouraged their followers to commit violence against Westerners, and particularly Jews. These risks will only grow as Israel's ground incursion into Gaza deepens , as it will undoubtedly lead to even more Palestinian casualties and accusations, regardless of veracity, of Israeli atrocities. Strong U.S. (and to a lesser extent European) support for Israel will further feed extremist narratives that frame the West, led by Israel, as the oppressor of Muslims. And should the Israel-Hamas War become a larger regional conflict, terrorist threats would rise even more.
