You're not alone. You should see how upset my Grandfather gets when I tell him this stuff.
Profit is why American companies sold tons of material to the Germans. Companies knowing the germans were using the raw material to build weapons.
Why didn't we stop selling Germany the material? Profit. In fact, American companies didn't stop selling to Germany until the president made it clear that "Further commerce with Germany would be treasonous"
Irony is when the raw material American companies sold to the Germans is used to take the lives of Americans. The profit was all that mattered.
So, yes, if you were an American soldier, killed by German weapons made from material sold by American Companies who knew there was a War effort in progress in Germany, Profit played a pivotal role in your death.
Hey, we sell them steel and chemicals... who cares what they do with it...? It's great for our bottom line...! German war effort, yeah right.
