In reply to:

but at what point down the road would both of those circumstances have changed?

Again, we come back to a point that requires wild speculation to justify acting now vs. later -- and VP Cheney is currently doing just that.

The facts are, Saddam was not an imminent threat, nor was he remotely close to becoming one. Cheney is using little tidbits of the recent report to infer that Saddam was holding out against the U.N. resolutions, while using the fuel for food program to buy off foreign countries, with the angle that these countries would eventually drop the sanctions, at which point he would resume production of WMDs.

Where's Occam's razor when you need it?
