WASHINGTON — The argument for going to war in Iraq was clearly made. Over and over again, Saddam Hussein was said to be a turn-of-the-millennium Hitler, a madman bent on destroying America with his stockpiles of weapons of mass destruction.
Of course, that turned out to be false, but at the time, the justification was no mystery. The word “weapons” shows up 1,107 times in the Congressional Record during the period when the House and Senate were voting to grant President George W. Bush the authority to use force against Iraq. The more specific “weapons of mass [destruction or murder]” comes up 368 times.
