I'd much rather have China admit fault and explain how this won't happen in the future than the current situation. As it stands I assume they are hiding something. For all I know they're developing bioweapons they plan to use for military purposes. And if they have nothing to hide then they have nothing to apologize for, but as it stands nobody is allowed to investigate so I have little faith in this theory.

I'm not pretending this isn't a political clusterfuck. But I'd rather deal with a political clusterfuck than a bioweapon clusterfuck. And if they aren't developing bioweapons then great! If they are developing bioweapons then that feels like something that's better to know sooner rather than later. And if there wasn't a lab leak then even better! Now the world knows that it really was just a bizarre phenomenon. If there was a lab leak then they simply made a mistake, they can rectify that mistake moving forward, and the world moves on. If the world doesn't move on - what are they going to do? You think the US (or any country) will go to war (as in send in troops in huge numbers with the understanding most of them will likely die) with China because of an accidental lab leak? I don't.

It seems to me the dumbest possible thing to do is not investigate. I don't believe advocating for ignorance is ever a viable strategy.
