1) We did not go to war over WMD - read the Congressional War Resolution; there is not one mention of Hussein possessing WMD at the time of its signing, or as a basis for removing his regime. His "capability to possess" WMD was one of the criteria that the Senators had to contemplate before voting on it, but not actual possession.
2) According to the two reports issued by the Iraq Survey Group, we've already recovered 41 rockets armed with sarin and/or cyclosarin, biological weapon seed stocks, rockets that violate U.N.-imposed range-limits, and WMD-related programs.
3) Apparently the U.S. government has evidence that the Russians (and probably the Syrians, as well), helped Hussein remove any WMD he had from Iraq. Therefore, we should be looking elsewhere.
But that's not the perspective the news media is conveying. They are trying to convey (successfully, I'm sure) that the search for WMDs has completely turned up empty, and that we're giving up. All of which reflects badly upon the US' decision to go to war (regardless of your other comment about the Congressional resolution, which is an excellent point).
In regard to looking elsewhear, I would very suprised if we don't have Special Forces in the Baaka Valley even as we speak.
