Last summer, in response to a directive from Chairman of the Joint Chiefs Martin Dempsey, the Joint Staff issued a short summary of lessons learned from the past decade of military operations. The document, entitled Decade of War, Volume 1 frankly and cogently acknowledges mistakes made over this period, and particularly during the first half of the decade, that is to say between the invasion of Afghanistan in late 2001 and the surge of troops into Iraq in early 2007. Among the admitted deficiencies were the failure to adequately grasp the operating environment, a reliance on conventional tactics to fight unconventional enemies, an inability to articulate a convincing public narrative, and poor interagency coordination. The document is testimony to the capacity of the American military for self-criticism and eventual correction, albeit not always in time to avoid costly setbacks
