“Secret cables and reports by the U.S., Saudi and Israeli intelligence agencies indicate that the moment Assad rejected the Qatari pipeline, military and intelligence planners quickly arrived at the consensus that fomenting a Sunni uprising in Syria to overthrow the uncooperative Bashar Assad was a feasible path to achieving the shared objective of completing the Qatar/Turkey gas link. In 2009, according to WikiLeaks, soon after Bashar Assad rejected the Qatar pipeline, the CIA began funding opposition groups in Syria.”The conflict in Syria is not a war in the conventional sense of the word. It is a regime change operation, just like Libya and Iraq were regime change operations.
