Douglas MacArthur couldn't have been a more widely recognized, honored and respected American military leader after WWII, but Harry Truman didn't hesitate to can him when he didn't seem to understand that the line of command in the USA starts with the president and adds several more layers of civilians before it gets to the military.
This is the way the Founders wanted it, to avoid military coups etc. But ever since the military became voluntary and rightwing Republicans (and need I add fundamentalist Christians) became the major influence in the military, which now lacked the broad citizen participation that the draft had guaranteed, the military has been critical of anything other than rightwing Republican (and need I add fundamentalist Christian) policies.
Thus the undermining of Carter, Clinton and now Obama. Mainly because the military has more power than any civilian agency, more money, more people, bigger staffs and press corps etc. not to mention all the fire power. Or almost all.
The question I would put to anyone supporting General McCrystal in his blatant political prejudices as expressed in that Rolling Stone article he knew was being written and therefore obviously wanted his opinions out there, is if you guys are so much better than your civilian bosses who were elected democratically, how come the war you've been fighting is now the longest war in our history and you're still not winning?!
As for the Reagan appointed Republican judge who just overturned Obama's six-month moratorium on drilling for oil on only a portion of oil rigs in the gulf, "activist judges" anyone?
All this just further proof of what I've been arguing on this blog and elsewhere since Obama got elected: he is up against an array of powerful rightwing forces in and out of the government that have become deeply entrenched at least since Reagan (though it began under Nixon) as the result of a deliberate strategy to control any and all political power in the U.S. Which means the destruction, by any means, of not just Democratic politicians even when elected by a majority of voters, but the destruction of all they stand for, including less power to the military and more to elected officials.
They are obviously out to destroy Obama's presidency (as they were for Carter and Clinton, by any means) and so they can gain control again and not have to answer to anyone other than their own rightwing coterie.
