Who is the Secretary of Defense?

The Secretary of Defense is a high-ranking official responsible for the nation's defense policies and ensuring the armed forces are ready to perform their missions. As of the latest information available before October 2023, the correct answer, which identifies the current Secretary of Defense, highlights the individual who leads the Department of Defense and advises the President on military matters.

Although Pete Hegseth may be a prominent figure in discussions related to military policies or veterans' affairs, he is not the Secretary of Defense. The other individuals listed do not hold the position of Secretary of Defense either, as they may represent different roles or ranks within the military or government, but none serve as the head of the Department of Defense. Understanding these distinctions is essential for recognizing the chain of command and responsibilities within the military leadership structure.
