The military’s resistance dates back to the summer of 2013, when a highly classified assessment, put together by the Defense Intelligence Agency (DIA) and the Joint Chiefs of Staff, then led by General Martin Dempsey, forecast that the fall of the Assad regime would lead to chaos and, potentially, to Syria’s takeover by jihadi extremists, much as was then happening in Libya. 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.
Lieutenant General Michael Flynn, director of the DIA between 2012 and 2014, confirmed that his agency had sent a constant stream of classified warnings to the civilian leadership about the dire consequences of toppling Assad. The jihadists, he said, were in control of the opposition. Turkey wasn’t doing enough to stop the smuggling of foreign fighters and weapons across the border. ‘If the American public saw the intelligence we were producing daily, at the most sensitive level, they would go ballistic,’ Flynn told me. ‘We understood Isis’s long-term strategy and its campaign plans, and we also discussed the fact that Turkey was looking the other way when it came to the growth of the Islamic State inside Syria.’ The DIA’s reporting, he said, ‘got enormous pushback’ from the Obama administration. ‘I felt that they did not want to hear the truth….’
