After controversial statements made by Corsi became public, O'Neill denied Corsi's coauthorship of the book, saying that Corsi was "simply an editor and not really any sort of co-author." However, portions of the book contain material also found in articles posted under Corsi's name at "WinterSoldier.com", a website critical of John Kerry, and O'Neill is cited in a later book as describing Corsi as helping to write "Unfit for Command", and urging him to back out of media appearances after the controversial comments became public.
