Bush does not write the rules of engagement in Afghanistan. And I'm certain nobody asked him for permission to hit that target.
You are probably right about Bush not being aware of that "silver platter". But how about sacking that official who made that decision? Who was it? Military or political? They did it on the Abu-whatever prison, why not here?
Gee, I always thought the president was commander-in-chief of the armed forces...thanks for correcting the Constitutional error.
Actually, ROE is determined at very high levels, and has NCA approval before it can be implemented in the field. Like everything else, the ROE is stated very broadly at the NCA level, and then defined more specifically at each lower level to conform to the intent of the CIC's approved ROE, while providing clear guidance to the warfighter. So in a broad sense, the President did approve the ROE, and his staff put it together.
That said, once the ROE is stated, field commanders should not need to ask higher ups for further approval to execute, unless such is required by the ROE.
