An interesting quote relevant to bio attention hazards from an old CNAS report on Aum Shinrikyo:
"This unbroken string of failures with botulinum and anthrax eventually convinced the group that making biological weapons was more difficult than Endo [Seiichi Endo, who ran the BW program] was acknowledging. Asahara [Shoko Asahara, the founder/leader of the group] speculated that American comments on the risk of biological weapons were intended to delude would-be terrorists into pursuing this path."
Footnote source in the report: "Interview with Fumihiro Joyu (21 April 2008)."
Just saw reporting that one of the goals for the Biden-Xi meeting today is "Being able to pick up the phone and talk to one another if there’s a crisis. Being able to make sure our militaries still have contact with one another."
I had a Forum post about this earlier this year (with my favorite title) Call Me, Maybe? Hotlines and Global Catastrophic Risks with a section on U.S.-China crisis comms, in case it's of interest:
