I have heard similar things about Petraeus from friends of mine in the Army. I am not a fan of the warrior/scholar/statesman model, and I think it almost always translates into shitty field commanders. However, promotion boards seem to get raging hardons for people with multiple academic degrees from Ivy League schools.
I looked for pictures online of Holly Petraeus when she was younger and she was a pretty lady. Time is not kind to everyone, but I am always impressed to hear what she has done for military families. However, I have no personal knowledge of it.
When I heard the name "Jill Kelley" it made me think of a completely different person. I'm really curious how this all will unfold.
