Anyway, good point, Roll. When people hear "concentration camp", this usually brings the image of an actual "death camp", so in effect one might think that Auschwitz had something in common with detention camps for the Japanese. Surely, the latter were a major violation of just about any right under the sun, but still nothing like the Nazi camps, which were desinged with one thing in mind, it's hard to accuse Roosevelt of a similar agenda.
Nazis had started building theirs a few good years before the war broke out, and most important of all - no one could ever leave once imprisoned.
In the case of American camps :
Nearly a quarter of the internees left the camps to live and work elsewhere in the United States, outside the exclusion zone. Eventually, some were authorized to return to their hometowns in the exclusion zone under supervision of a sponsoring American family or agency whose loyalty had been assured. Many Japanese internees were temporarily released from their camps- for instance, to harvest Western beet crops- to address this wartime labor shortage
When the government circulated a questionnaire seeking army volunteers from among the internees, 6% of military-aged male respondents volunteered to serve in the U.S. Armed Forces.[citation needed] Most of those who refused, however, tempered that refusal with statements of willingness to fight if they were restored their rights as American citizens. 20,000 Japanese American men and many Japanese American women served in the U.S. Army during World War II.
The 442nd Regimental Combat Team, which was composed primarily of Japanese Americans, served with uncommon distinction in the European theatre of World War II. Many of the US soldiers serving in the unit had their families interned at home while they fought abroad.
The famed 442nd Regimental Combat Team, which fought in Europe, was formed from those Japanese Americans who did agree to serve. This unit was the most highly decorated US military unit of its size and duration.
