Only one year ago the idea that green on blue attacks were systemic seemed preposterous, but today the idea is tenable. Insider attacks are clearly increasing. In the last year alone over fifty allied troops have lost their lives to supposed Afghani allies; only last Saturday two more US troops were killed. One in five, or 14 per cent, of combat deaths are due to insider killings. The issue hangs as a question mark over the heads of NATO leaders, with little clear grasp of the matter.
