If it will really happen (I hope that no), how West would react to it? Last month Biden said that US and NATO would respond to it.
There are unconfirmed reports that some "substance" was released from a drone. Could be false (calling Basurin's bluff), not sure.
Funny (not really) thing about Basurin and other DNR/LNR nutjobs - Russia can claim that these "independent" states haven't signed any international agreements regarding chemical weapons. And when I say "can", I mean Kremlin trolls are already doing it in comments on Russian sites, coming soon to Reddit/Youtube/etc.
It would make tactical sense (that is, if Putin's psychos decide so) since that would allow capturing the installations with minimal damage. I am not sure what kind of response would come to the use of chemical weapons or how would Putin try to cover up the mess after.

I guess that means that troops in those territories cannot claim that any treaty has then been broken if their soldiers are treated inhumanly? Seems to cut both ways?
