To me a lot of the rationale for focusing on bio is that the magnitude of harm from a really scary bio attack is extremely high, as it could spread to be a global pandemic, with a high / possibly 100% fatality rate. I’m not aware of ways to do comparable amounts of harm with chemical weapons, so my sense was that this was lower priority. But I may just be ignorant of ways to do vast amounts of harm with chemical weapons?
