I would be very interested to hear a soldier's view on this. My time in theatre involves kinetics but from an air conditioned cockpit; nerve wracking and fraught but well removed from the sights and sounds of mortal combat.
We have seen the USMC urination incident, the NATO Koran burning incident and now the US Army mass murder incident.
I was always of the opinion that the progress made would be incremental and very fragile. A year's or decade's good work and incredible sacrifice could be undone by a nano-second's action.
If a soldier was to tell me that the three above events are unavoidable and someone will always let the side down due to the very nature of what we are asking of them - then we are lost and cannot win. If a soldier was to tell me that these horrendous incidents are not undoing their amazing work on the ground then I shall keep the faith.
