Regarding the war effort, when any part of our intelligence apparatus produces a report that reflects negatively on the Bush administration or any part of the war effort, it is quickly cited by those on the left as proof of Bush's incompetence, dishonesty and/or failure of the war effort. The veracity of this intelligence is taken as unassailable -- its accuracy beyond dispute.
For instance, recent intelligence reports from the CIA stated that Al Qaeda had rebuilt its capabilities to pre-9/11 levels and that it is concentrated in tribal areas of Pakistan. These reports were pounced upon as proof that the war against terror was a failure -- because we haven't destroyed Al Qaeda and bin Laden -- and as proof that we are wasting our time fighting in Iraq because Al Qaeda is actually elsewhere.
However, when an intelligence report from the administration reflects positively on any of Bush’s claims or the war effort, the left immediately dismisses it as a fabrication
