In a new defense strategy submitted to Congress on Wednesday, President Bush warned Iraq and other hostile countries that the United States is prepared to use "overwhelming force" -- including nuclear weapons -- in response to any chemical or biological attack.
The threat was contained in a White House document called the "National Strategy to Combat Weapons of Mass Destruction." Presidential spokesman Ari Fleischer called it a declaration "of how seriously the United States would take it in the event that weapons of mass destruction were used."
