If history should teach us anything, it's that we always tend to fund, train and organize our military around fighting the last war and/ or the aftermath of it instead of looking forward to growing threats. If Bacevich is brilliant, as you attest, he should acknowledge this. I suspect his grief and guilt projection onto an administration that was less than adroit in such matters, no matter how just and honorable the effort may have been, and signing on to Obama "smart power" as a sufficient way of military power projection is clouding his thought process.
Look again at what Bacevich wrote. His first paragraph argues for the same point you are making.
I can’t explain his support for Obama. I never talked politics with him. I also can’t explain my in-laws support for the Democrat party.
I don’t know the whole story about Camp Doha. I realized early in my career that when somebody died or was seriously injured in peacetime that the first line supervisor would be fired. The second line supervisor would be fired and the third line supervisor would be retired. The Navy is the same way. If your ship runs aground, you get fired. You could be the Captain of the ship and be sound asleep when the ship runs aground. It doesn’t matter. You get fired. It’s not always fair, but it sends a message about how important some things are. Bacevich is brilliant and was a great warrior. It appears that he was unlucky (coupled with some mistakes) and he took responsibility and the Army lost a great leader. You can rail against your luck all you want. It just is. Somewhere, there’s a former artillery Soldier whose actions with a heater had a tremendous effect on today’s Army.
