I hate being a hindsight historian, but man that EO was so bogus and disgraceful.
Maybe in Hawaii it could have made sense, but even then it never was implemented there because their were so many ethnic Japanese that there was no way to enforce it.
They proved to be some of the most American-Americans, at least far more than many people of German lineage.
“... that EO was so bogus and disgraceful.”
Desperate, times, desperate measures. Sometimes taking a wrong action than dithering and taking no action at all. We certainly should have learned that with Bill Clinton.
