According to one scientist I’ve seen commenting on this, much of the bioweapon research today is for incapacitating agents, not lethal ones. He said other weapon systems are more efficient at killing large numbers of people. What they are going for are biological agents that could be slipped in a country surreptitiously that could spread and cause chaos and disruption to society. So in that sense covid would seem to fit the bill.
The societal disruption was generated by our Deep State, not by China.
