The upcoming book – "Known and Unknown" – will hit book stores January 25 and "is filled with previously undisclosed details and insights about the Bush administration, 9/11, and the wars in Afghanistan and Iraq," according to the book's publisher, Sentinel, a division of Penguin.
The book's title harkens to his infamous 2002 quote explaining there were "known unknowns" and "unknown unknowns" when it came to the war in Iraq – a word jumble that Rumsfeld critics found emblematic of his inartful leadership.
And if there is any doubt Rumsfeld will reveal new details, the former defense secretary is planning to launch a website to coincide with the books publication that will feature previously undisclosed documents.
"It's both a fascinating narrative for today's readers and an unprecedented resource for tomorrow's historians, said Sentinel president and publisher Adrian Zackheim The manuscript delivers everything I was hoping for and much more."
Rumsfeld has largely dodged the public eye since his abrupt resignation from the Pentagon the day after the 2006 midterm elections – when the Republican party lost control of Congress largely because of the unpopularity with the war in Iraq.
It remains unclear how much Rumsfeld was paid to write the memoir, but he is pledging to donate the book's proceeds to veterans' charities
