The article also claims that if France doesn't join up, then the cost of the war will be much higher for the US. I find this laughable - as has been mentioned recent US military actions have carefully avoiding putting any non-Anglosphere forces on a critical path.
Sadly, I must do a little defense of France. After reading multiple accounts, it's clear that the statement "We [France] believe that today nothing justifies envisaging military action" is clearly with reference to Iraq and the evidence that has been found to date, not in abstract and in general. I find that claim risible but not utter lunacy. It doesn't really matter - if we go in I have no doubt that we'll find evidence of French and German cooperation with Saddam's regime. Their intrasegience will cost them the remains of respect from the US, destroy NATO and potentially break up the EU. The castigation of the blogosphere is rather pale compared to that.
