This book looks at internal intelligence community procedures that lead to failures in Iraq and Iran. It sidesteps the role of political actors/policy makers in these events. As such it is largely apolitical and of more interest to people in the intelligence community and political science academics.
The assessment of Iraq contradicts a lot of the journalistic reporting on the events (the presence of WMD was a rational view unaffected by political pressure). It’s interesting in this regard because it looks for ways the intelligence community could have given a more accurate assessment without judging the background political environment.
