To see the Aug 6 PDB as a historical narrative is certainly one reading, and perhaps fits in with Condi's overall deconstruction that national security is impossible to influence because failure is inherent in its structure. Furthermore, threats to security are above human recourse and could only be stopped by a silver bullet, a different narrative perhaps, but still not her fault. The future is impossible to predict; the past is impossible to judge.
But Condi isn't the only member of this administration who is influenced by postmodernist theory. Shrub himself seems a little too comfortable with the both the idea and the utility of "revisionist history" as a political tactic.
Funny you wouldn't think this would be a group so at home with critical theory.
Frankly, I prefer postmodernist interpretations limited to literature. I would like a National Security Advisor who doesn't raise the question: "It depends on what your definition of threat is."
