What i rant is put more eloquoently by Pakistan Army. Once again for you which you purposely chose to ignore completly
"Due to complicated chain of command, complex command and control structure and unimaginative/intricate Rules of Engagement (all acknowledged in US/ISAF investigation report), the responsibility for failing to stop the attack rests squarely on US/ISAF. Pakistan Army on its part had, on numerous occasions and at all levels, highlighted the potential problems associated with not having all the forces in the Afghan theatre under a unified command. The activities and operations of US Special Forces and Afghanistan Border Police are but two examples, which have been raised consistently by the Pakistani side. The incident of 19th July 2011 in Angoor Adda Sector of South Waziristan Agency was also, we believe, a result of lack of unified military command in Afghanistan"
Just to rephrase my self, American Unit commander on field without informing superiors about his motives purposefully fed the wrong coordinates to Pakistani military attache and took matter in his hands completely and called in the airstrike and during the aerial strikes on pakistani checkposts, The unit commander updated is superiors and got the correct info, the time was passed and pakistani check posts were leveled completly
