South Vietnamese. His view that the U.S. Army was not learning from its mistakes, and that South Vietnamese ARVN officers were essentially corrupt and ineffective, created friction with Army leadership. In early 1971, Hackworth was promoted to the rank of colonel and received orders to attend the Army War College, an indication that he was being groomed for the general officer ranks. He had declined a previous opportunity to go to the War College, and turned down this one, as well, indicating his lack of interest in becoming a general and demonstrating his discontent with the war and the Army's leaders. Hackworth's dissatisfaction ultimately culminated in a television interview with ABC. On June 27, 1971, he appeared on the program Issues and Answers and strongly criticized U.S. commanders in Vietnam, said the war could not be won and called for U.S. withdrawal. The interview enraged senior U.S. Army officers at the Pentagon. He subsequently retired as a colonel. Senior Army leaders investigated Hackworth, who avoided them for several weeks.

He also made regular television appearances to discuss various military-related topics, and the shortcomings of the military. His commentary on the psychological effects of post-traumatic stress disorder, based on his own experiences in overcoming it, resonated with disabled veterans. In the mid-1990s, Hackworth investigated Admiral Jeremy Michael Boorda, then Chief of Naval Operations. Hackworth, through his Newsweek articles, questioned Boorda's longtime wearing of two bronze "valor pins" (in the Navy, the "V" device was worn on certain decorations to denote valor
