Petraeus is a political general.
He obviously made a deal.....Chairman of the Joint Chief’s or NSA advisor....in exchange for his “support” of “o”.
If he wasn’t political, he would have resigned also, in order to send a very strong message to “o”, and then run for president.
Petraeus is finally in the driver’s seat....
I just hope that he uses that driver’s seat to demand what he needs - and tell Obama where to go if he even thinks of giving him less than what he needs. If he’s really worthy of the respect the rank-and-file have for him, this will be his biggest test.
