First of all, this means the Syrians confirm they are in possession of chemical weapons.
Secondly, chemical weapons of this sort aren't usually stored already mixed. In order to have an affect on people they must have been "armed" by mixing the components.
So they confirmed that they lied about destroying them all during the Obama Regime and confirmed that they're lying about the US bombing stored munitions.
Sarin and Chlorine do not require mixing before disbursal.
And, the Syrian General Staff does not, by their accusation of US bombing an ISIS storage facility, that Syria possesses CW.
How do you deduce that?
“...the Syrian General Staff said that the US-led coalition struck an ISIS depot storing chemical weapons...”
An ISIS Depot of chemical weapons.... how does that confirm the Syrian government has chemical weapons? You should really check out news back in 2013-15, even US news. Isis has their “scientist” working on creating chemical weapons.
