This isn't about disarming Iraq, or even about the containment of an evil dictator guilty of war crimes. No, this is a French self-absorbed pity party. The sun will shine on France indeed, but they may not be prepared for the rat infested sewer that is revealed by the light of day.
(the meaning is: After Iraq is free there will be sufficient documentation to reveal French duplicity, French political malfeasance, and French military industrial-complex whoring.)
