3. lol. Seriously? Allow me to speed up the process.
At a certain level, general officers are little more than lobbyists for defense contractors, certain politicians, or some security consulting group/think tank/board, etc. General officers aspire. Oh, how they do aspire.
I've spent 20 + years around the military - in the company of general officers, as well - and know they are political creatures. Many are out for what they can get using their pretty little ribbons and brass. It's about the $$$ and what they can get once they do retire. Some want political fame - some want the consulting gigs, and some want both. While in uniform they entertain the defense industry giants and are entertained by them. Everything that is attached to lobbying in the civilian world (trips, freebies - women/men) can also be found within the military. It's an environment ripe for abuse.
Then there's the usual bad attributes of power - I'm the boss, it's my way or no way, influence over jobs/rank....same as it can be with any person in a position of power. You're top dog so you see yourself as entitled.
The lack of accountability that has gone on for years upon years. You can rightfully think of yourself us untouchable if accountability is for people with less rank, less power. Which is all too often how it plays out within the military.
I have no doubts that I will be amused by what the Pentagon has to say on the subject.
