More can always be said on this matter, so if anyone would like to look deeper into the topic of internment in the US during the Second World War, please, don't let this post stop you!

• u/DBHT14 examines a few aspects here;
• u/kieslowskifan has an excellent overview of the matter;
• and u/abuggyreplay goes a bit deeper on the Japanese-American internment.
