There was a war on?
Not between Afghanistan and ISAF.
Most Afghans took no part and welcomed ISAF.
The war is between Al Q. (who declared it and launched the 9/11 attack among others), and ISAF and the Afgham national forces.
Shame on Al Q for using kids to fight for their despicable beliefs. (Do you support any of those beliefs McG.?)

POWs are normally incarcerated until hostilities cease.
