A series of recent terror attacks and foiled plots in Australia, Germany, and the United States have reignited fears about the West's vulnerability to ideologically driven violence. The deadly shooting at a Hanukkah event in Sydney, arrests of suspected militants planning a Christmas market attack in Germany, and the disruption of a bombing plot in Los Angeles all point to a resurgence of extremist threats targeting symbolic gatherings. Analysts warn that these incidents reflect a new era of diffuse violence, with attackers often acting independently but inspired by global ideological movements. The events have sparked intense debate among Western leaders and security experts about whether current policies and counterterrorism measures are sufficient to address the evolving threat landscape.
