Instapundit has a good post on the shutdown of the Iraq survey group, and I would add one more point.
The persons who are jumping up and down in glee because no WMD were found in Iraq (thereby, in their opinions, vindicating their position) conveniently omit one inconvenient bit of information. Those same people argued that Iraq should not be invaded and Saddam should not be removed even if Iraq possessed WMD. Thus, the full argument is that the U.S should not have invaded Iraq and toppled Saddam regardless of whether it had WMD.
Want to test this? Ask any anti-warn type or Bush-hater whether he or she would support the war or Bush if WMD were found in Iraq tomorrow.
