I am really interested in the social-political dimension of this. Was the initial hypothesis of a lab leak suppressed during the initial part of the pandemic primarily due to Western government's fear of a diplomatic breakdown (like Russia) with China? The economies are far more interdependent than compared to Russia and there is a far more economically important Chinese diaspora in the West.
What would it take to get a honest investigation within China? Presumably not under the current regime - if it were true, the magnitude of the disaster would be 100x what Chernobyl was for the Soviet Union, it wouldn't just be an accident at that point.
Would it totally legitimize the Chinese state in the eyes of its people and the world? And for that reason, could we ever expect a honest accounting? Too much blood (literal and metaphorical) has been spilled and with the lockdowns, vaccine mandates, passports, school closures, etc and everything else that has happened, most elite institutions, state actors, businesses, media, corporations have become complicit in some way in abuses, lies, deliberate obfuscation of one type or another.
It feels like a breakpoint in history to me.
