The September 11 attacks in the U.S. led to significant global events, most notably the initiation of the War on Terror. In response to the attacks, the U.S. launched military operations in Afghanistan to dismantle al-Qaeda and remove the Taliban from power. This event also triggered widespread security enhancements globally, including changes in airport security and international diplomatic relations. The attacks fueled a resurgence of discussions around national security, counterterrorism measures, and intelligence sharing among countries, fundamentally altering the geopolitical landscape and leading to ongoing conflicts in the Middle East.
