An editorial from a retired diplomat decrying the military as a closed society is about as unconvincing as any souce that I can think of. It's disingenuous but instructive for this retired ambassador to say that his profession values negotiation to achieve its ends as though the Military does not. The difference between State Department culture and military culture is far more about details- The military values quantifiable action with concrete steps to achieve outcomes and conducts negotiations from the perspective that negotiations work best when there is both a carrot and stick, and that the negotiation is not in itself an outcome. Diplomats by contrast are always sketchy on details, timelines and the nuts and bolts of how things are accomplished.
From my perspective there is in reality far less of a gulf than the periodic "concerned talking heads" like to portray. People in powerful positions from any walk of life in our society have perks and prerogatives that are far beyond what the "average joe" gets. What do you call it when salaries for upper level management people in the financial industry are in the millions? I alternate between amusement, anger and envy when the corporate plane disgorges senior executives for them to bring us the word from on-high about our latest corporate plans. The social circle that senior people live in is always a limited one drawn largely from those who are in similar circumstances- people making a high six figure salary don't typically live in developments that also have 3 room bunglows- or go to any college town in America and see how much the faculty mingles outside of their peers? And yet unlike civilian society, military leaders largely have to make their way up the ladder in their chosen profession from near the bottom to the top, living and working side by side. So they at least have some idea of what they are asking of their people and how those impact their people in their daily lives and jobs- unlike much of the Civilian sector of the economy which routinely seems to think that brilliance in money handling is the key to all management ,and that people and resources are just numbers on spreadsheets.
I have had the privilege of working for a long period time in both camps- and from my perspective, military society is no more a closed and rarified world than any other large organization. It has its fair share of people who lead secret lives without moral grounding, and it has its share of folks who are oblivious to the trends outside their circles as well as it fair share of those who progress up the chain by sucking up and by brilliant packaging rather than solid performance. But the military certainly has no more of those than any other organization or segment of society. If I have a beef with military life, its more grounded in what Tom Ricks has noted in his latest book- that there is an increasing unwillingness to hold senior military leadership accountable for failure. That to me is a far bigger issue than the "isolation" of military society from the larger civilian one that this guy decries.
