Who was the Secretary of Defense mentioned?

The correct answer is Leon Panetta, who served as the Secretary of Defense from July 2011 to February 2013 under President Barack Obama. His tenure was marked by significant military engagements and a focus on defense strategy in an evolving global landscape. Panetta was previously the Director of the Central Intelligence Agency (CIA) and had a notable career in public service, which included a role as a Congressman.

Hillary Clinton, while an influential figure in American politics, served as Secretary of State, not Secretary of Defense. Jim Matheson and Mike S. Lee are also prominent political figures but have not held the position of Secretary of Defense. Understanding the roles and contributions of these individuals is essential in grasping the broader context of U.S. defense policy during their respective tenures.
