Peter Hegseth, a former Fox News host and Army National Guard veteran, has been nominated by President-elect Donald Trump as Secretary of Defense. Known for his conservative views, Hegseth has criticized "woke" military policies, called for reinstating traditional combat standards, and suggested renaming the Defense Department to the War Department. His lack of senior military or national security experience and controversial stances on women in combat and NATO have sparked bipartisan concerns. (Source: BBC)
