Body and Soul links to this article suggesting that Bush's advisors, confronted with the Adminstration's profound failure to sway the UNSC ("You will lose, Mr. President," Powell told Bush. "You will lose badly and the United States will be humiliated on the world stage."), may be looking for an exit strategy, and this WaPo op-ed in which William Raspberry quotes Washington lobbyist Nick Ashmore making some of the same points I've been making:
"It seems to me that somebody should be pointing out that we have Iraq pretty much right where we want them -- under constant observation. Under those circumstances, Saddam won't move against us or move to aid Osama bin Laden or anything else that constitutes a clear and present danger to us. And if he does, not even the French could argue against massive retaliation."
On the other hand, Ashmore says, a war launched in the name of preventing terrorism could have the effect of increasing it.
...Ashmore thinks it is as important to understand the likely consequences of the war as to grasp the justification for war in the first place. If we could make that dilemma our focus, he suggests, we might even help our president find a way out -- or else unify the rest of the world behind him.
