Does this character realize that, "everyone in authority in the US-Afghan chain of command," includes, by Constitutional definition, President Obama?!
Since I don't buy into this character's apparent, if-only-Comrade-Obama-knew warmongers-ordered-the-bombing-of-DWB (could some one inform me as to with what country bombing DWB would incite war?) conspiracy theory, here's what I think probably happened:
* DWB informed people in the chain of command in Afghanistan of their location;
* Local Afghan people (or Afghan authorities) reported the DWB facility to US intelligence people as a Taliban facility;
* US intelligence people organized the strike, and the people who organized the strike didn't talk to the people who knew of DWB's presence.
That assumes, of course, that that particular DWB operation had not gotten co-opted or infiltrated by Talibanders, and wasn't, in fact, providing medical support to terrorists.
One irony in this (apparent) screw-up is that a Nobel Peace Prize winner who did nothing to earn it BOMBED a Nobel Peace Prize winning group who did dangerous work to earn it.
