Bush says fight against terror is 'World War III'

In an interview with the financial news network CNBC, Bush said he had yet to see the recently released film of the uprising, a dramatic portrayal of events on the United Airlines plane before it crashed in a Pennsylvania field.

But he said he agreed with the description of David Beamer, whose son Todd died in the crash, who in a Wall Street Journal commentary last month called it "our first successful counter-attack in our homeland in this new global war -- World War III".

Bush said: "I believe that. I believe that it was the first counter-attack to World War III.

"It was, it was unbelievably heroic of those folks on the airplane to recognise the danger and save lives," he said.
