Very detailed report from HRW:

Lessons in Terror: Attacks on Education in Afghanistan
Brutal attacks by armed opposition groups on Afghan teachers, students, and their schools have occurred throughout much of Afghanistan in recent months, particularly in the south. These attacks, and the inability of the government and its international backers to stop them, demonstrate the deteriorating security conditions under which many Afghans are now living. While ultimate responsibility lies with the perpetrators, much about the response of the international community and the Afghan government can and must be improved if Afghanistan is to move forward. The situation is not hopeless, yet....
Pages 109 to 114 of the pdf file are an analysis of the effect, or lack thereof, of military nation-building efforts in Afghanistan. A fairly close look is taken at the PRT concept and results.


Note: I know there are those who disdain any reporting from "Human Rights" organizations. However, I have a great deal of respect for the professionalism and balance of HRW, buttressed by personal observations of some of their personnel in action in Northern Iraq when they were still carrying out investigations into Saddam's Anfal operation against the Kurds.

Admittedly, there are times when their black-and-white views don't mesh well with the multiple shades of gray in the world we operate in, but I have found HRW to be very careful and precise in its findings and judgements. This is in great contrast to AI, which tends to be far more strident, and often exemplifies the reasons why many in the military look down upon "Human Rights" sources.
