This study critically examines the United States’ strategic and administrative response during the twelve-day Israel-Iran war of June 2025, with a focus on precision airstrikes against Iranian nuclear facilities in Natanz, Arak, and Fordow. The intervention is situated within the broader collapse of the Joint Comprehensive Plan of Action (JCPOA), Iran’s revived nuclear program, and its continued support for regional militant proxies. Employing a qualitative case study approach, the paper draws on policy cycle theory and crisis governance frameworks to analyze how rapidly evolving security threats were transformed into state action. The roles of the National Security Council (NSC), Department of Defense (DoD), and Central Intelligence Agency (CIA) are assessed to understand interagency coordination, executive decision-making, and operational execution under high-pressure conditions. The analysis contributes to public administration and international security scholarship by exploring the intersection of military strategy, administrative processes, and international legal norms. It highlights both the tactical effectiveness and post-conflict governance deficits of the U.S. response, raising critical questions about legitimacy, accountability, and long-term diplomatic outcomes. Ultimately, the study underscores the evolving role of public administration as a critical actor in managing 21st-century crises involving hybrid threats and nuclear escalation.
