I would just like to say, as a disclaimer, that I have no experience in government intelligence or at think tanks or anything like that. Although, I do feel I have read enough news reports and enough news analysis so that I think I have a good feel for what's going on in the world.
Shane has questioned the basic thesis of my analysis: that the NIE report will be used in negotiations over Iraq. Let me say this: This isn't why the intelligence was produced, but how it will be used.
Also, the thesis makes perfect sense. The government could have hushed up the report and never had it released. Or, they could have had it released, but criticized and attacked it and ripped it to shreds. But they haven't.
