Former U.N. Secretary-General Kofi Annan says former British Prime Minister Tony Blair could have averted the invasion of Iraq in 2003.

Annan, in an interview with The Times of London, said he wonders what would have happened if Blair had told former President George W. Bush he would not go to war without a second U.N. resolution.

"I really think it could have stopped the war," he said. "It would have given the Americans a pause. It would have given them a very serious pause to think it through. ... All this would have raised a question: 'Do we go this alone?'"
