It is accepted that the American medical and military communities benefitted from the findings of the Japanese and German experiments on live prisoners.
Morally, we never could have conducted those experiments themselves.
Example: Germans froze Russian POWs in ice water, and took meticulous notes. We used that info after the war to assess pilot survivability.
I understand the value of live experiments...
The part of his post I though was strange is “mostly forgiven”
A better word might be “overlooked”
In my book live human experiments can never be forgiven...
