There is nothing in any of those citations saying or proving we provided arms to ISIS. There is only speculation. Unsourced speculation is not proof. If we provided arms to ISIS then why did we train and arm FSA which is fighting ISIS? Why are we bombing ISIS? Why are we coordinating attacks against ISIS with the Kurds, Iraqis and Syrians?
....So the British armed Hitler at Dunkirk?
"The president has made a decision about providing more support to the opposition that will involve providing direct support to the [Supreme Military Council]. That includes military support," Deputy National Security Adviser for Strategic Communication Ben Rhodes told reporters.
"direct [] military support". It could not be more clear.
From Foreign Policy as cited in post 49
"The decision saddles the CIA with providing arms to vetted rebel fighters in the country."
Again, it could not be more clear.
The US has been arming Syrian rebels. It's indisputable.
I reiterate the second sentence of my original post (45), "Various groups in Syria are not formal groups, their membership is a fluid collection of terrorists." This is why it was foreseeable that "bad" rebels would obtain these arms. In fact is was foreseen, this from October 2012:
For months, Saudi Arabia and Qatar have been funneling money and small arms to Syria’s rebels but have refused to provide heavier weapons, like shoulder-fired missiles, that could allow opposition fighters to bring down government aircraft, take out armored vehicles and turn the war’s tide.Petraeus coordinated an airlift of materiel from these other countries to Adana, Turkey, and then to the Syrian rebels. The US clandestinely supplied arms prior to the "red line", and overtly thereafter.While they have publicly called for arming the rebels, they have held back, officials in both countries said, in part because they have been discouraged by the United States, which fears the heavier weapons could end up in the hands of terrorists.[1]
