Good folks to lead such, imho, are not that easy to find in a lot of circles. I don't know about the military on that score but I suspect they are above average as a group of candidates. Setting one's own biases aside is particularly difficult to impossible for arrogant, stubborn types who believe their own press reports. They tend to think they have an accurate corner on reality.
