Bush: Terror war a 'struggle for civilization'

President George W. Bush, on the fifth anniversary of the September 11 attacks, said Monday his campaign against terror "is a struggle for civilization" in which defeat would leave the Middle East overrun by terrorist states armed with nuclear weapons. "We are fighting to maintain the way of life enjoyed by free nations," Bush said in remarks prepared for an evening television address from the Oval Office. The speech was coming at the end of a day in which Bush paid tribute to the memory of the almost 3,000 people killed in the attacks that rocked his presidency and thrust the United States into a costly and unfinished war. "Our nation has endured trials, and we face a difficult road ahead," the president said.
