United States Department of Defense
The executive department of the U.S. government responsible for the United States Armed Forces and national security. In 2026, the department is managing a high-intensity kinetic campaign against the Iranian regime while overseeing a strategic realignment of global assets and industrial mobilization.
The United States Department of Defense (DoD), headquartered at the Pentagon, serves as the operational nerve center for American military power. Under the leadership of Defense Secretary Pete Hegseth and the Chairman of the Joint Chiefs of Staff, Gen. Dan Caine, the department has shifted to an aggressive posture in the Middle East throughout 2026. This shift followed a series of escalations, including the downing of a U.S. Army Apache helicopter in the Strait of Hormuz, which prompted the department to recommend direct kinetic strikes against Iranian infrastructure to restore deterrence.
Currently, the DoD is overseeing 'Operation Epic Fury,' a sustained military campaign against the Iranian regime. A September 2026 report from the Pentagon's Inspector General revealed the immense scale of this conflict, noting a cost of $33.4 billion over a four-month period. The intensity of the air campaign and defensive intercepts has led to strategic ammunition shortages and bottlenecks in the defense industrial base, necessitating emergency industrial mobilization. Despite these challenges, the department continues to execute high-stakes operations, including the targeting of over 6,000 facilities in Iran.
Beyond regional conflict, the DoD maintains its role in military justice and internal security. In October 2026, the department confirmed the presidential approval for the execution of Nidal Hasan, the terrorist responsible for the 2009 Fort Hood attack. This marks the first U.S. military execution since 1961, reflecting a firm stance on counter-terrorism and accountability within the ranks. For Israel and the broader Jewish world, the DoD remains the primary partner for security cooperation, intelligence sharing, and the maintenance of regional stability against Iranian-led aggression.
