Washington ? Defending his credibility, President Bush said Monday the United States made the right decision to invade Iraq and the intelligence on which he relied was “darn good” — even though some of it now is in question.

Bush said the United States was reviewing documents in an intensive effort to support the administration’s still unproven claim that Saddam Hussein had weapons of mass destruction.

“When it’s all said and done,” Bush insisted, “the people of the United States and the world will realize that Saddam Hussein had a weapons program.”

Bush spoke in the Oval Office alongside U.N. Secretary-General Kofi Annan.

Bush has been on the defensive since the administration acknowledged it could not document his claim in January that Iraq had been trying to buy uranium in Africa to develop nuclear weapons.
