Despite repeated public pronouncements from President Obama, Susan Rice, and others in the Obama administration that a 2013 deal with Russia and Syria had eliminated Syria's declared chemical weapons program, the evidence from continued attacks increasingly and overwhelmingly contradicts this assertion. As recently as Jan. 16, former national security advisor Susan Rice told NPR in an interview, We were able to get the Syrian government to voluntarily and verifiably give up its chemical weapons stockpile.
Rice's statement is being roundly mocked in light of last week's chemical attack in Idlib province. But a year-old report released by the Obama administration's own State Department, which received little attention at the time, also undermines the claims regarding the success of the 2013 deal. The April 2016 report, titled Compliance With the Convention on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons and on Their Destruction Condition 10(C) Report, was not limited to Syria, but also covered Iran, Iraq, and Russia, which may explain why it was underreported. The report's section on Syria specifically, however, is fairly devastating to the Obama administration's case.
