The U.S. Army War College (USAWC) recently hosted its 2025 Homeland Defense Symposium, gathering experts to tackle the complex issues of defending the homeland. A key focus was clarifying the difference between Homeland Security (law enforcement and emergency response) and Homeland Defense (military protection against external threats). Bert Tussing, Director of the Homeland Defense and Security Issues Group at the USAWC’s Center for Strategic Leadership, joined host Ron Granieri in the studio to discuss the major themes of the symposium. Participants emphasized the importance of preparedness, highlighting that future conflicts are likely to reach U.S. soil. The discussions emphasized the need for a whole-of-society approach, integrating not just federal agencies but also state and local governments, the private sector, and the general public into defense strategies.
The term homeland defense may be unfamiliar to many listeners more accustomed to the phrase Homeland Security. These differences are significant even if the policies are intended to be complementary.
