A WMD Attack On The United States?

Confederate Yankee reminds us that there has already been one (and only one) WMD attack on our country. It was in 1993: the first attempt to bring down the World Trade Towers. The person who put cyanide in the bomb that was a dud fled to Iraq, where he was protected by Saddam Hussein until our 2003 attack, which resulted in the deaths of Saddam's evil sons and the imprisonment and trial of Saddam.
