Tonight on Special Report with Brit Hume:

Jim Angle reports: Iraq must fully disarm to avoid war, President Bush says, as he urges the United Nations to "honor its word" and back U.S. action against Saddam Hussein.

Guest preview: Will ousting Saddam Hussein's regime bring new changes or inflame old problems for Iraq? Deputy Defense Secretary Paul Wolfowitz gives us his take.

Plus:

• The resolution submitted by Britain, Spain and the United States, saying Saddam Hussein must disarm -- or else -- sets the stage for a U.N. Security Council showdown on whether to authorize war or give more time for weapons inspections.

• South Korea's new president calls the nuclear dispute with the North "a grave threat to world peace," as the communist nation upstages his inauguration by test-firing a missile and accusing the United States of spying.

• A U.S. Army UH-60 Black Hawk helicopter crashes in Kuwait during a night training mission, killing all four crew members.
