You've got to understand something about the brass, although most of them have earned the right to be in elite military positions, it takes a 30+ years of politicing, maneuvering, and living the life of a super-bureaucrat in order to win favor into those positions. At some point, a lot of them become consumed, and there remains very little of the original man or woman when the layers are peeled back. Another problem I see frequently in DC is that the senior 06 to O8 officers get a solid 10-15 years of having their butts kissed by most everyone else, and sometimes that only makes it worse.
When I see senior military officials sounding like elitist bureaucrats from Washington, it doesn't surprise me much. At some point in their career, for some of them, after a lifetime in DC, it's all that's left. Mcxrystals comments are an embarrassment, as was his departure.
