AMY GOODMAN: Can you talk about similarities or differences you see between the lead-up to the invasion of Iraq and what’s happening now with Iran?
SCOTT RITTER: The biggest similarity that we need to point out is that in both cases no evidence was put forward to sustain the allegations that are being made. Iraq was accused of having weapons of mass destruction programs, reconstituting chemical, biological, nuclear, long-range ballistic missile programs. There was an inspection process in place that had access, full access to the facilities in question, and no data was derived from these inspections that backed up the Bush administration's allegations. And yet, Iraq was told, it’s not up to the inspectors to find the weapons. It’s up to Iraq to prove they don't exist. Iraq had to prove a negative. And they couldn't. We now know that in 1991, Saddam Hussein had destroyed the totality of his weapons programs. There weren’t any left to find, discover. There was no threat.
We now have Iran. It’s alleged to have a nuclear weapons program. And yet the International Atomic Energy Agency, the inspectors who have had full access to the sites in Iran, have come out and said, “Well, we can’t say that there isn’t a secret program that we don’t know about. What we can say, as a direct result of our investigations, there is no data whatsoever to sustain the Bush administration's claims that there is a nuclear weapons program.” And yet, the Bush administration once again is putting the onus on Iran, saying, “It’s not up to the inspectors to find the nuclear weapons program. It’s up to the Iranians to prove that one doesn’t exist.” Why do we go down this path? Because you can’t prove a negative. There’s nothing Iran can do that will satisfy the Bush administration, because the policy at the end of the day is not about nonproliferation, it’s not about disarmament. It’s about regime change. And all the Bush administration wants to do is to create the conditions that support their ultimate objective of military intervention.
(bold added by me). I'm not posting this as if it's some kind of big revelation that the Bush administration wants to attack Iran, I just thought maybe some other people would be interested in the video.
