The Department of Homeland Security (DHS) is a prolonged state of strategic drift somewhere along the middle seam of a full spectrum of 21st century threats. This paper explores the National Security Act of 1947 and the Goldwater-Nichols Act of 1986 as case studies of unity of effort for large, complex organizations. Then, it investigates the Homeland Security Act of 2002 to provide historical context and define the current strategic environment of DHS. Finally, it proposes recommendations that will help the Department fully profit from economy of force by institutionalizing unity of effort and broadening its succession leadership capability. As the threat spectrum continues to evolve, so too must the capacity of the homeland security enterprise to properly protect the American people and the homeland. In order to increase this capacity, Congress should enact comprehensive reform legislation allowing DHS to accomplish its mission.
