I think that had the guy shot and killed ANA I would have agreed. For you to suggest that killing women and children is retribution for those rogue elements of ANA that have done for coalition troops smacks of My Lai. All Vietnamese are Vietcong and deserve to die eh?
He does not seem to have been very selective, just walked off base and let rip, nervous breakdown they say, poor bugger, might be those long Septic tours.
Not a diagnosis you hear when a ANA guy goes postal but unfortunately the effect will be much the same, more dead USAF folk. Kandahar Terry will be delighted, obviously not as useful as staging a Quran barbecue but a little sweetener for them.
It would be a mistake to think that "wandering off base" could only happen with our allies. Another point is that we know nothing at this stage about how long this US soldier had been in theatre, so it is a bit premature to discuss 12 month tours on the basis of this incident.
