That would _not_ be a good justification to wage a war, but I think the actual casus belli was Saddam Hussein's weapons of mass destruction – later found to be non-existent. 215 Republicans and 82 Democrats voted for this. They paved the way for a war of aggression… and I seem to remember that Americans have previously hanged foreign politicians for precisely that.

Edit: Misread above comment and thought he was talking about Iraq. Point still stands, though.
