20m plus died in WW1 and 60m plus in WW2, were no where close to that. Even the worst estimate dont come close to that high.
So how are u going to make someone pay for this. China isn't going to take accountability for it, its never going to make it to the courts at the UN. They just hammered out the best trade deal for us with China so they aren't going to mess that up. So short of starting WW3, which would be by far the most likely outcome in any confrontation with China, how do u suggest we get our pound of flesh making someone pay.
