...There are two possible explanations as to why Centcom may have sought to make it sound as though the campaign was going better than it actually was, i) national intelligence director James Clapper pulled a Dick Cheney and pressured Maj. Gen. Steven Grove into delivering upbeat assessments, or ii) The Pentagon and the CIA were content with ineffectual bombing runs because intelligence officials were keen on keeping Islamic State’s oil revenue flowing so the group could continue to operate as a major destabilizing element vis-a-vis the Assad regime.

Or there is a third reason.The US and Turkey are behind ISIS and have been for some time.

One now wonders about the link at Benghazi where the late Chris Stevens headed up the CIA smuggling operation of arms to Turkey that went to Syria. Were these arms eventually winding up in the hands of ISIS back then?Could that have been the reason Stevens had to go? He knew entirely too much? Inquiring minds....

Timmerman wrote Dark Forces with this explanation. The Iranian Revolutionary Guard pulled off the attack on Benghazi to get arms out of the hands of rebels attacking Assad, their guy. They paid off the locals who provided security; locals we were paying to protect the buildings, to abandon their posts.
