Yup, it's the same reason why most people now see the Japanese internment as unjust. They just know we won the war and fail to connect the dots that the internment was potentially critical to winning the war.
Is this an accepted view among historians? I'd like to know more about that.
There was a widespread, mostly inaccurate perception in the West that Japan's incredible territory gains early in the war must have been due to fifth-column agents preparing the battleground.
