He already answered that question in 1998:
Asked about the military rules under which Zinni might have the authority to again re-target Iraq, he said he would only have the right to take action if Saddam Hussein's forces took some offensive action against U.S. military forces who are enforcing sanctions against Iraq through the no-fly zones in the north and south of Iraq or through the nearby maritime intercept operations.
Iraq's Weapons of Mass Destruction Capabilities Diminished
One more quote from 2000 for good measure:
What we ended up with after the Cold War was chaos. It is getting worse. The number of failed or incapable states are going to grow. The growth of extremism. The danger now with things like weapons of mass destruction. We are going to have a WMD event. Mark my words. Will it be on the battlefield or will it be back here in Tampa or New York City? I dont know. But we will have one, and that is going to be a wake-up call. It is a dangerous world out there. We need to make the commitment and understand that if we want to maintain our position in the world, then we need the capability to provide for the world to be a safe place, to be a place that is stable.
General Anthony C. Zinni Commander in Chief, Central Command AFA Air Warfare Symposium 2000
He saw the threat back then...what happened? Oh that's right...he's trying to sell a book.
Nice research, very nice.
"........ We are going to have a WMD event. Mark my words. Will it be on the battlefield or will it be back here in Tampa or New York City? I dont know. But we will have one......."
Since Zinni doesn't believe this to be true anymore, is it fair to say that W's war on Terror has been a success?
