One only needs to apply basic game theory and skepticism to come to the conclusion that Assad has no incentives to gas citizens. He's winning the war!
On the other hand who would benefit from a gas attack? Obviously, the "rebels" (read islamists). They have been losing ground for the past two years and if the US pulled out (which was planned) and a peace settlement is reached then they would lose.
Now consider that the exact same sequence of events happened almost exactly the same time last year -- the US announced that "regime change is no longer a priority" and a few days later we saw reports of a gas attack. See http://www.moonofalabama.org/2018/04/timelines-of-gas-attack...
