Cute, but factually incorrect insofar as the Sovs were putting vast resources into biological warfare R&D right up until the Wall came down.

There's an island in the Caspian Sea accidentally contaminated with weaponized anthrax about twenty years back. The cover story was an industrial accident with chemical contamination, but the island was and is uninhabited.

There was also an incident in the 1970s in which something extremely nasty (weaponized ebola, according to some sources) got loose from a lab and depopulated several towns in western Siberia.

Yes, the Sovs signed treaties in the early 70s saying they were giving up all biowar research. They then ignored that treaty, like they ignored all the others.
