While his new book details tense relationships within his administration and admits mistakes were made in the execution of the Iraq War, former president George W. Bush totally blanked on the 9/11 terrorist attacks while writing his memoir Decision Points. 'He ends one chapter on what seems like a telling note, saying he felt nothing significant had happened in his first six months in office, but then the next chapter begins, 'It was almost Thanksgiving, and my approval rating was sky-high,'' reviewer Glen Harwell wrote Thursday, noting that Bush's account of the 2001 presidential turkey-pardoning dominates the next 3,000 words of the book. 'It appears he just plain forgot to mention what many would call the defining moment of his presidency.' Bush has already received criticism for claiming in the memoir that the worst moment of his years in the White House came when entertainer Kanye West sharply criticized him 'over issues I cannot even recall at this time.'
