Dal Combating Terrorism Center di West Point l’ultima raccolta di documenti qaedisti ritrovati nel corso delle operazioni in Iraq: "Dysfunction and Decline – Lessons Learned From Inside Al‐Qa`ida in Iraq".

Come scritto nella breve introduzione: "Readers should be aware that analyzing such data is fraught with risk. Documents in the Harmony database were collected on the battlefield unscientifically. There is no way to know how representative documents captured by U.S. forces are of the larger body of information produced by al‐Qa`ida or other insurgents. Likewise, the vast database in which they are stored is imperfect and virtually impossible to search systematically.
Readers and researchers should therefore be wary of conclusions drawn solely from these documents. Captured documents offer unique insight into al‐Qa`ida’s decisionmaking process, but they are most valuable when contextualized with information drawn from open sources."
