Apparently an unnamed official has decided that Ambassador "Eikenberry's detailed assessments be made public, given that they were among the most important documents produced during the debate that led to the troop buildup." Given that the debate within the administration is over for the time being, the President has decided on a policy, and the policy is being implemented - oh, and that the cables are, ya know, classified - this strikes me as a really bad idea at this juncture.
Really, other than undermining any residual trust among senior officials (especially between civilians and military) and pissing off the Commander in Chief, what exactly is this going to accomplish?
Given the, ahem, vigor of his disagreement with McChystal last November, I was dubious that Eikenberry was a real contender for the soon-to-be-created top NATO civilian in Afghanistan. This would seem to make it all the more unlikely, and maybe that was the real point of the leak.
I've yet to read the cables themselves carefully, but the NYT's summary of the arguments makes them sound pretty weak: dangers of Afghan over-dependency (reminiscent of Iraq under Casey, and someone forgot to tell the Brits in SL); and I believe Lil could write a short dissertation in response to Eikenberry's concerns about the ANSF on why the conventional wisdom about attrition rates in ANA don't capture the whole story...that said I'm going to reserve judgment until I've read the originals in full.
