As the 25th anniversary of the September 11 attacks approaches, experts and commentators reflect on the enduring impact of that historic event on American democracy, counter-terrorism strategies, and international relations. While some argue that the War on Terror has not failed, there is a growing concern that lessons from 9/11 have been overlooked, leading to a potential resurgence of terrorist threats within the U.S. Furthermore, debates continue about the effectiveness of the U.S. response, with discussions around institutional neglect and the changing face of terrorism. Analysts caution that a unilateral American approach in a post-unipolar world may exacerbate security challenges, while the legacy of 9/11 continues to shape public perception and policy. As the nation grapples with these complexities, a call for reflection and renewed vigilance against terrorism remains crucial.
