You'd have to be a massive rough ridin' idiot to think Petraeus is scum.
why?
Well first off he hasn't done anything to be considered a war criminal. Only the ignorant leftist freshmen in college types level that kind of charge. If you look at his entire career he is pretty freaking brilliant. From his terrific education (PhD from Princeton) to his career in uniform he did an amazing job and saved many lives on both sides with his reworking of American COIN strategies against a heavily entrenched doctrine of how to fight. Find a copy of the FM 3-24 and read it. Read the other works by his adherents like LTC John Nagl and see how they approached COIN and make up your own mind I guess.
Now his CIA career is something we can debate, but I don't really take issue with it too much. For one I don't have a lot of qualms about the drone program in areas of Pakistan the government has lost nearly totally control of. But he was given a list by the CiC and told to execute a plan with these tools. He did it.
His personal life is obviously a eff up. But lots of guys eff up their lives like that. As long as it didn't bleed over into operational security, I can deal with it.
Patreus was a total stud in the surge, from a military tactical POV.
I didn't know he had fallen out of favor.
Not really correct on the 'tactical pov' but thanks for trying.
