Chapter 2: Structuring Homeland Security

Structuring Homeland Security details the transition of the security landscape from the 1947 National Security Act to the post-9/11 paradigm shift that necessitated the creation of the Department of Homeland Security (DHS) via the Homeland Security Act of 2002. Central to this study is the adoption of an all-hazards approach, a strategy expanded by the lessons of Hurricane Katrina to encompass not only counterterrorism but also natural disasters, public health emergencies, and critical infrastructure protection. The text explores the internal structure of the DHS, categorizing its various operational and support components—such as FEMA, TSA, and the Coast Guard—while addressing the complexities of interagency coordination and the challenges of extensive congressional oversight. Furthermore, the chapter analyzes the fiscal dimensions of security through the federal budgeting process, overseen by the Office of Management and Budget (OMB) and influenced by strategic documents like the Quadrennial Homeland Security Review. Comparative perspectives highlight how the United States’ integrated model differs from the organizational frameworks of international partners, specifically examining Canada’s trade-centric border policies and Britain’s committee-based CONTEST strategy. Finally, the material presents a scholarly debate regarding the efficiency and necessity of the current DHS structure, weighing the benefits of operational synergy against criticisms of bureaucratic redundancy and jurisdictional overlap.
