homeland defense
Guarding one's country
Homeland defense refers to military and security measures protecting a nation's territory from external threats—enemy attacks, terrorism, or invasion.
The term gained prominence in American political discourse after the September 11 attacks: The department coordinates homeland defense efforts across agencies.
It emphasizes defense of domestic soil rather than projecting force abroad.
