Yeah I've encountered people like, "hey well if we find out it was China then there should be consequences." Uhh like what? Are we going to invade a nuclear adversary who the whole world is 100% dependent on and with a population of 1.4 billion people to shut down their labs that maybe produced a virus?
The best payback for millions of accidental deaths: a billion purposeful ones all over the globe and very possibly the destruction of human civilization itself.
