The material confirms what most of us sane people out on the blogosphere have been saying all along... Afghanistan is a disaster, with thousands of civilian casualties (at least).
It's unlikely I'll have time to analyse the thousands of pages of material in depth any time soon, but hopefully there'll be plenty of other people doing that.
This just underlines the spectacular military misadventure that was the Bush administration. And if Obama and Cameron have any sense they will get the hell out of Afghanistan. And fast, before who knows how many thousands more lives are lost.
