Not forgetting the US uncessingly trying to undermine the weapon inspections to their own end, according to Blix [1]
Before Blix was sent in, again the cover of "International" weapons inspection (note, not US inspections) were subverted by the US spying and constant attempts to discredit the results if they were wrong (wrong as in not the US version of events) [2]
[1] Blix didn't say the US "uncessingly" tried to undermine the inspectors. He said that he believed there had been a single leak from someone in the US Government about Blix's failure to report two weapons, and was unable to say who did it -- "Also disturbing, he said, was the question of who was responsible for the falsification."
[2] Spy agencies spy. That is to be expected.
