The Inspector's role is that of a verification monitor, not of a detective ala "Inspector Clusoe". This man is a willing dupe for self-interested reasons. We are not being unilateralists - France is!
Regarding your post, I agree that the US honors single veto power in the UN Security Council. The BEEF, however, is that the French will be voting against the inspectors - because the next UN resolution will go something like this - - -
1) Iraq has failed to submit a complete declaration of WMD in it's possession. -- T or F
2) Iraq has failed to provide unconditional and proactive cooperation with UNMOVIC. -- T or F
3) Iraq has an active concealment and denial program, as related by intelligence shared with the UN Security Council by the US Secretary of State, contrary to provision of UN Resolution 1441. -- T or F
4) Iraq remains in material breach of 16 former resolutions passed by the UN Security Council since 1991. -- F or F
The UN Security Council affirms that all of the foregoing statements are true.
That's all that it needs to say. Period.
Let them vote against it.
Maybe then we can actually get the US out of the UN, and the UN out of the US.
