I'm sure that China can't be held accountable for coronavirus pandemic. Such kind of polemic may lead to terrorism. It's more important to do all possible to stop the pandemic now. Blaming won't help here.
Don't be so sure. They should be held responsible.
The virus has traces of SARS that has not been seen for years and that also originated in China. Do you really believe that after dealing with SARS epidemic they simply left it at that and kept living their lives? They were conducting extensive research at all fronts to make use of all possible applications, and those include biological warfare. Covid-19 is a mutated version of SARS, an enhanced version. For this reason SARS was contained in Asia and Covid hit the whole world. Probably the only weakness of this virus is hot and dry air that kills it fast and slows the spread.
