No, I’m just pointing out that your comparison is flawed. We didn’t know about the Holocaust until the war was almost over. The Soviets were the first to discover and liberate the camps back in 1944 (too bad they ended up having their own brutal camps) and the Americans liberated the first camp they discovered (Ohrdruf) in April 1945… the war in Europe was over in a month. That’s when the then general Eisenhower ordered the American soldiers to find the other camps, free the captives, and take pictures of everything they came across so Nazi crimes can be thoroughly documented and the American public can be made aware of them.
My point is that we didn’t intervene in the war because of what the Nazis were doing like you seem to imply, we intervened because we got attacked and declared war on.
