You are proving to be an idiot. And I am noted for my tolerance.
Did you even bother to comprehend David Petraeus's assertions? He did not dismiss contacts of ISI with some militant groups:
"there's communication between the ISI and various militant groups in FATA and Balochistan (Haqqanis, Taliban, Islamic Movement of Uzbekistan, etc) but some of it you'd do anyway as an intelligence service."
That is not a secret anymore. However, Petraeus understands the importance of such contacts because he knows how intelligence agencies are supposed to work. He even stated this:
"there may be some degree of accommodation that is forced on them (Pakistanis) because of the limits of their (Pakistan's) forces."
However, he dispelled the myth that there is some grand conspiracy from ISI to jeopardize American mission in Afghanistan:
"I looked very very hard then (as US commander in Afghanistan) and again as CIA director at the nature of the relationship between the various (militant) groups in FATA and Baluchistan and the Pakistan Army and the ISI and I was never convinced of what certain journalists have alleged (about ISI support of militant groups in FATA).... I have talked to them (journalists) asked them what their sources are and I have not been able to come to grips with that based on what I know from these different positions (as US commander and CIA director)".
His point is that sensational journalism is responsible for that kind of disinformation or impression. And he is right.
