Simone Ledeen is an American national security policy advisor and government official, best known for her role in the Trump administration from 2017 to 2021. As the daughter of prominent neoconservative scholar Michael Ledeen, a national security expert who served as Deputy Assistant Secretary of Defense for Counter Narcoterrorism and Global Threats during the Trump administration, she has followed a path in foreign policy and defense-related work. Ledeen served as a special advisor in the Office of the Secretary of Defense, focusing on strategy and global threats, with her work emphasizing countering threats from Iran, China, and other adversaries, aligning with hawkish conservative viewpoints on international security.

Prior to her government service, Simone Ledeen was involved with conservative think tanks, including the Foundation for Defense of Democracies (FDD), where she contributed to research on Middle East policy and counterterrorism. She has advocated for strong U.S. military postures abroad and has been part of networks influencing Republican foreign policy. Ledeen holds a background in political science and has engaged in advocacy on issues like sanctions against adversarial regimes. Her career reflects the influence of her father's neoconservative legacy in Washington policy circles.

Ledeen has maintained a relatively low public profile compared to her father, focusing on behind-the-scenes advisory roles. She has been associated with efforts to promote democratic values through robust defense strategies, though specific personal details such as early life or post-administration activities remain less documented in public sources.
