From Butros: ""A former senior adviser to the Joint Chiefs told me that the document was an ‘all-source’ appraisal, drawing on information from signals, satellite and human intelligence, and took a dim view of the Obama administration’s insistence on continuing to finance and arm the so-called moderate rebel groups. By then, the CIA had been conspiring for more than a year with allies in the UK, Saudi Arabia and Qatar to ship guns and goods – to be used for the overthrow of Assad – from Libya, via Turkey, into Syria. The new intelligence estimate singled out Turkey as a major impediment to Obama’s Syria policy. The document showed, the adviser said, ‘that what was started as a covert US programme to arm and support the moderate rebels fighting Assad had been co-opted by Turkey, and had morphed into an across-the-board technical, arms and logistical programme for all of the opposition, including Jabhat al-Nusra and Islamic State. The so-called moderates had evaporated and the Free Syrian Army was a rump group stationed at an airbase in Turkey.’ The assessment was bleak: there was no viable ‘moderate’ opposition to Assad, and the US was arming extremists."
