Flynn was a director of DIA who has developed a reputation in some circles for sounding off in retirement. I saw him do an interview on Al Jazeera, ballsy by the way, where he stated that "history will prove the invasion of Iraq to be a strategic disaster". It's worth watching. Personally, I like the guy.
Idaho posted on inflammatory piece on here that didn't get any replies about the absolute failure of a program to arm/train rebels to fight the Assad regime, and the general in charge Nagata ended up with a promotion. Foreign Policy did a big spread on him some months maybe a year back.
It was something like 200 million for 5 guys. There was quite a bit of discussion about it in some of the more discriminating news/commentary outlets.
Circumstantially, this fits with Hersh's allegations, and the military understands the problem of green on blue violence better than most. Arming/training guys that will end up indiscriminately killing Americans along with whoever else they want dead is probably not something they want to be a part of, especially if they conclude that the program will not be capable of achieving its goals.
Hersh's problem is he used to be a true investigative journalist that exposed some major cock ups, and has turned into publishing rumor-mill gossip bullshit.
You'll probably hear much more about this period in 30-40 years when most of the principal actors are dead or senile, assuming we are all still around.
