9/11 Attacks Prompted New U.S. National Security Framework

Why it matters locally: The post-9/11 national security framework led to increased federal funding and resources for state and local law enforcement agencies across Missouri, impacting operations of bodies like the Kansas City Missouri Police Department and the St. Louis Metropolitan Police Department. Missouri's two major airports, St. Louis Lambert International Airport and Kansas City International Airport, also experienced significant changes in security protocols and federal oversight.

The September 11, 2001, attacks introduced a new category of national security threat for the United States. In response, U.S. officials established a new national security architecture designed to counter these challenges. This new structure aimed to address vulnerabilities identified following the attacks. Officials prioritized a comprehensive approach to national security operations. They focused on adapting existing governmental capabilities to meet the evolving threat landscape. The reorganization involved various government entities and their functions related to security. The changes reflected a significant shift in U.S. national defense and intelligence strategies. Policy makers implemented measures intended to prevent similar future events.
