I’m not going to say China has a bad system or disagree with Communism – something that would put me at odds with @Robert Lindsay. Not on this post anyway.
The point being that regardless of whether China’s ways are something you like, you can’t deny it’s evolutionary for them to hate the US because we are the other power. It would make sense that Covid-19 is a bioweapon but only if it were kept secret, mainly to avert panic. I wouldn’t be surprised if Trump and the Pentagon got in some secret meeting and agreed to keep it Top Secret.
