On February 19, 1942, soon after the beginning of World War II, Franklin D. Roosevelt signed Executive Order 9066. The evacuation order commenced the round-up of 120,000 Americans of Japanese heritage to one of 10 internment camps—officially called "relocation centers"—in California, Idaho, Utah, Arizona, Wyoming, Colorado, and Arkansas.

There are many modern day prison camps in the USA. I know of one in Otay Mesa, CA. This one processes and deports 1,300 "aliens" per day. Many of these "aliens" are parents of children born in the US, are homeowners and leave behind young children. It is also a holding camp for incoming refugees. Conditions there are terrible with three people to one cell. Deplorable.

dear God, that makes me so ashamed. and one of the craziest things about the whole internment camps during ww2 was that the japanese were the only ones incarcerated, because germans and italians weren't as easily identifiable as those of japanese descent.

i wonder if another part of the reason was the "they're not like us" thing. we can be such weiners.

Many countries have used internment during wartime. In Britain, also during WWII, German political and Jewish refugees were considered ‘enemy aliens’ and viewed with great suspicion; rounded-up and interned. Because many of them were native German speakers with region-specific dialects, intelligence agencies recruited some to work on ‘black propaganda’ operations. When Italy entered the War, large numbers of Italian residents were also interned.
If the truth be known, perhaps something similar happened in the US too.
