They should be held responsible but, is America ready for an international body with authority over the worlds countries and capable of holding even America at fault if we were found negligent and the cause of a major pandemic?
Some say, mostly they say there is no consenus on where it started.
It didn't start in Spain of course. Kansas is considered because they had Doctors capable of diagnosing but much evidence suggests it came from farther afield than Kansas however it was spread most widely from there.
Past pandemic's don't matter. If we have a world order, nations can be held accountable. If you don't believe in a world order, don't bitch about where any pandemic originates. You can't have it both ways.
