Related to Were chemical weapons being used in the civil war in Syria before 2014?.
While the consensus at the time seemed to be that the government was using chemical weapons (this in particular was the position of the US government), and that there was reasonable grounds for assuming that chemical weapons had been used, there seems to be increasing popular dissent with this view. However, it is unclear to me whether this popular dissent is just an internet factoid, or something based upon solid evidence that has since emerged. With the benefit of hindsight, does it now seem likely or unlikely that the government of Syria specifically used chemical weapons on civilians? This is separate from whether chemical weapons have been used at all during the course in the civil war.
