Has Russia REALLY Destroyed Its Chemical Weapons ???

According to this report, Russia has completed the destruction of its chemical weapons:

But we should not celebrate yet, for at least two reasons:

1. They did not incinerate all their weapons - they merely broke them down chemically; and
2. The Novichok series of weapons was not covered by the Chemical Weapons Convention and possibly could be reconstituted from the residues of what they DID "destroy".
