In 1967, Robert McNamara, the U.S. Secretary of Defense, was overwhelmed by the turmoil of the Vietnam War. He was seen pacing anxiously in his Pentagon office, visibly emotional as he gazed at a photograph of Forrestal, a former Defense Secretary who had tragically taken his own life. This moment reflected the deep personal and professional crisis McNamara was experiencing amid the escalating conflict.

By the end of that year, President Lyndon B. Johnson had lost confidence in McNamara's ability to manage the war effort. The prolonged and devastating conflict had severely shaken even the most self-assured leaders, highlighting the profound impact of Vietnam on American leadership and the psyche of key policymakers during this period.
