Washington, Feb.8 (ANI): Former US Defense Secretary Donald Rumsfeld has conceded that "it's possible" that decisions on how many troops to send into Iraq marked the biggest mistake of the war.
"In a war, many things cost lives. The most important failure in the execution of the war," said Rumsfeld.
The interview-Rumsfeld's first for television since 2006 -- is tied to the publication of his memoir, "Known and Unknown," this week, reports ABC News.
The book spans a half-century that took Rumsfeld, now 78, from a back bench as a 30-year-old member of Congress to success in the private and public sectors.
He served Republican presidents from Richard Nixon to George W. Bush, including a stint as President Gerald Ford's chief of staff.
Remarkably, he would become both the youngest and oldest man to have served as secretary of defense-tenures separated by 24 years. (ANI)
