One of the things which surprised me during covid was how e.g. Turkic central Asian states not only had clearly well-funded bio labs, but sometimes even their own vaccines (effective, too!) quickly in production.
The conclusion I drew from that is that people like Gurbanguly Berdimuhamedow have asked a lot of questions about bioweapons in secret for a long time. And if he did it, you bet all similar leaders, in a wide sense, did it too. And I wouldn't like to be the scientist who got approached by security state people with these questions.
I guess I'm not conveying this well. What I'm trying to say is that we're not at all confident about anything like that - none of us - because it's all so hush hush because it's WMD-adjacent. The secrecy cripples our ability to have an honest well-informed discussion about it.
