The National Security Enterprise

Book excerpt: This second edition of The National Security Enterprise provides practitioners' insights into the operation, missions, and organizational cultures of the principal national security agencies and other significant institutions that shape the US national security decision-making process. Unlike some textbooks on American foreign policy, this book provides analysis from insiders who have worked at the National Security Council, the State Department, Department of Defense, the intelligence community, and the other critical entities included in the book. The book explains how organizational missions and cultures create the labyrinth in which a coherent national security policy must be fashioned. Understanding and appreciating these organizations and their cultures is essential for formulating and implementing coherent policies. This second edition includes four new chapters (Congress, DHS, Treasury, and USAID) and updates to the text throughout. It covers the many changes instituted by the Obama administration, implications of the government campaign to prosecute leaks, and lessons learned from more than a decade of war in Afghanistan and Iraq.
