The White House’s misrepresentation of what it knew about the attack, and when, was matched by its readiness to ignore intelligence that could undermine the narrative. That information concerned al-Nusra, the Islamist rebel group designated by the US and the UN as a terrorist organisation. Al-Nusra is known to have carried out scores of suicide bombings against Christians and other non-Sunni Muslim sects inside Syria, and to have attacked its nominal ally in the civil war, the secular Free Syrian Army (FSA). Its stated goal is to overthrow the Assad regime and establish sharia law. (On 25 September al-Nusra joined several other Islamist rebel groups in repudiating the FSA and another secular faction, the Syrian National Coalition.)
The flurry of American interest in al-Nusra and sarin stemmed from a series of small-scale chemical weapons attacks in March and April; at the time, the Syrian government and the rebels each insisted the other was responsible. The UN eventually concluded that four chemical attacks had been carried out, but did not assign responsibility. A White House official told the press in late April that the intelligence community had assessed ‘with varying degrees of confidence’ that the Syrian government was responsible for the attacks. Assad had crossed Obama’s ‘red line’. The April assessment made headlines, but some significant caveats were lost in translation. The unnamed official conducting the briefing acknowledged that intelligence community assessments ‘are not alone sufficient’. ‘We want,’ he said, ‘to investigate above and beyond those intelligence assessments to gather facts so that we can establish a credible and corroborated set of information that can then inform our decision-making.’ In other words, the White House had no direct evidence of Syrian army or government involvement, a fact that was only occasionally noted in the press coverage. Obama’s tough talk played well with the public and Congress, who view Assad as a ruthless murderer.
Two months later, a White House statement announced a change in the assessment of Syrian culpability and declared that the intelligence community now had ‘high confidence’ that the Assad government was responsible for as many as 150 deaths from attacks with sarin. More headlines were generated and the press was told that Obama, in response to the new intelligence, had ordered an increase in non-lethal aid to the Syrian opposition. But once again there were significant caveats. The new intelligence included a report that Syrian officials had planned and executed the attacks. No specifics were provided, nor were those who provided the reports identified. The White House statement said that laboratory analysis had confirmed the use of sarin, but also that a positive finding of the nerve agent ‘does not tell us how or where the individuals were exposed or who was responsible for the dissemination’. The White House further declared: ‘We have no reliable corroborated reporting to indicate that the opposition in Syria has acquired or used chemical weapons.’ The statement contradicted evidence that at the time was streaming into US intelligence agencies.
Already by late May, the senior intelligence consultant told me, the CIA had briefed the Obama administration on al-Nusra and its work with sarin, and had sent alarming reports that another Sunni fundamentalist group active in Syria, al-Qaida in Iraq (AQI), also understood the science of producing sarin. At the time, al-Nusra was operating in areas close to Damascus, including Eastern Ghouta. An intelligence document issued in mid-summer dealt extensively with Ziyaad Tariq Ahmed, a chemical weapons expert formerly of the Iraqi military, who was said to have moved into Syria and to be operating in Eastern Ghouta. The consultant told me that Tariq had been identified ‘as an al-Nusra guy with a track record of making mustard gas in Iraq and someone who is implicated in making and using sarin’. He is regarded as a high-profile target by the American military.
On 20 June a four-page top secret cable summarising what had been learned about al-Nusra’s nerve gas capabilities was forwarded to David R. Shedd, deputy director of the Defense Intelligence Agency. ‘What Shedd was briefed on was extensive and comprehensive,’ the consultant said. ‘It was not a bunch of “we believes”.’ He told me that the cable made no assessment as to whether the rebels or the Syrian army had initiated the attacks in March and April, but it did confirm previous reports that al-Nusra had the ability to acquire and use sarin. A sample of the sarin that had been used was also recovered – with the help of an Israeli agent – but, according to the consultant, no further reporting about the sample showed up in cable traffic.
Independently of these assessments, the Joint Chiefs of Staff, assuming that US troops might be ordered into Syria to seize the government’s stockpile of chemical agents, called for an all-source analysis of the potential threat. ‘The Op Order provides the basis of execution of a military mission, if so ordered,’ the former senior intelligence official explained. ‘This includes the possible need to send American soldiers to a Syrian chemical site to defend it against rebel seizure. If the jihadist rebels were going to overrun the site, the assumption is that Assad would not fight us because we were protecting the chemical from the rebels. All Op Orders contain an intelligence threat component. We had technical analysts from the Central Intelligence Agency, the Defense Intelligence Agency, weapons people, and I & W [indications and warnings] people working on the problem … They concluded that the rebel forces were capable of attacking an American force with sarin because they were able to produce the lethal gas. The examination relied on signals and human intelligence, as well as the expressed intention and technical capability of the rebels.’
