The sections of that book about Biopreparat were deeply unsettling. Knowing the lengths they went to keeping the program a secret, it wouldn't shock me if they did continue to develop or conduct secret research on biological weapons after 1995. With nuclear weapons you want everybody to know you have them, but bio weapons by nature are secretive. It's the kind of cruel and horrifying weapon that even your own people can't know about.
Russia is even now accusing the US of hosting Biolabs in Ukraine to make weapons specifically targeted at Slavic peoples. I'm sure someone in the world is doing it, even if Russia is just making stuff up here.
