David French hits it our of the ball park with his timely editorial here entitled "America’s Brave Soldiers: Lions Led by Donkeys". It's worth reading in entirety.
In 14 years of continual combat, has there ever been a greater disconnect between our warrior class and the civilians who purport to lead them? American politicians still don’t understand our enemy, still don’t understand the capabilities and limitations of the American military, and — worst of all — they still seem unwilling to learn. They come from an intellectual aristocracy that believes itself educated simply because it’s credentialed — and they tend to listen only to those who share similar credentials. They’ve built a bubble of impenetrable ignorance, and they govern accordingly.
... But the politicized Pentagon bears its own share of the blame — beginning with a politically correct culture where discrimination complaints are more harmful to careers than battlefield failures. Yale- and Oxford-educated Ash Carter is no doubt intelligent (he has a Ph.D. in theoretical physics) and may be an upgrade over Chuck Hagel, but he has exactly as much experience in uniform as the commander-in-chief. On his watch, the Pentagon has maintained rules of engagement that have so dramatically hampered American forces in the field that terrorists routinely and easily find safe haven from the world’s most capable military.
... I do not believe that military service is a prerequisite for the presidency, but lack of service — especially lack of service since 9/11 — should lead to a degree of humility and openness to counsel that our political aristocracy self-evidently doesn’t possess. I know their world. I’ve lived in their world. This is a political class that reflexively distrusts the military, believes the right kind of experience can be gained by attending panel discussions from Boston to Geneva to Istanbul, and claims to gain on-the-ground insight from quick, guided tours of the safest sectors of Iraq and Afghanistan. They know nothing. Worse, they learn nothing.
