What was one major consequence of the 9/11 attacks on homeland security policy?

The major consequence of the 9/11 attacks on homeland security policy was the fundamental restructuring of the federal intelligence community. In response to the vulnerabilities exposed by the attacks, there was a critical need to enhance information sharing, coordination, and collaboration among various intelligence agencies that had operated largely in silos before. This restructuring included the establishment of the Department of Homeland Security and the reform of agencies like the Central Intelligence Agency and the Federal Bureau of Investigation to prioritize counterterrorism efforts and improve their operational effectiveness.

The events of 9/11 highlighted the gaps in intelligence that allowed the attacks to occur. As a result, significant reforms were initiated, such as the implementation of the Intelligence Reform and Terrorism Prevention Act of 2004, which aimed to improve the way intelligence is gathered, analyzed, and disseminated. This restructuring brought a greater emphasis on preventing terrorism and integrating efforts across the federal, state, and local levels, thus fundamentally altering how the United States approached domestic and national security matters post-9/11.
