I have no idea why we would want someone whose experience is primarily military as president. By temperament , training and focus, they aren't terribly well suited for the job. Eisenhower, because he was primarily a political general was an exception. Even in his case, maybe his biggest achievement, the highway system, was focused on a military objective.
We really need someone who understands the dynamics of the political system, how democracy really works, something most career military honor in the abstract while working in a system that doesn't practice it, and how to form consensuses, another trait not all that militarily common. Currently, they have to do that while taking a mile of crap from the opposition. I really don't see the role for someone with a primarily military background as president again. There's a hell of a lot more problems in our country that need a civilian approach and fewer a military one than probably about any time in our history.
