No, I think to some extent the "strategery" team is winging it. (But they "wing it" damn good.) I don't think Bush really wanted to go to the U.N., except for rubber stamp approval after an alliance for "regime change" had been formed. Instead, due to resistance to the notion of regime change, they had to go to the U.N. to advance the issue. Bush met 'em halfway with the not-quite-explicitly-stated implication that Saddam could forestall regime change by strict compliance with U.N. resolutions.
Now Saddam is going to pretend that he is willing to follow the compliance path, and some of our allies are going to pretend that they believe him. The strategery team, although certainly hoping for intransigence from Saddam, can't have failed to anticipate this, but I'm not sure they have a preplanned response. The immediate need is clear enough: to stop short any international rush to declare the crisis solved. We'll just have to see where they go from here. I'd guess they are furiously negotiating to get a very strict new resolution from the security council obligating Saddam to requirements beyond mere WMD inspectors. What this article suggests is that Russia no longer views further U.N. resolutions as necessary. This is a problem that needs to be dealt with quickly.
