1939
___
The US government knew about:
1. Ordinary concentation camps - from March 1933.
2. Extermination camps - from December 1941.
3. Nazi ghettos for Jews - from about November/December 1939.
Ghettos, concentration camps and extermination camps.
ghettos and camps were two different things.
POW camps for the Japanese, but NOT in the Pacific. In the United States itself were POW camps held. They were for the Japanese whom were deemed spies for the Japanese government.
Camps, by far. Ghettos held only a couple of million people, where as there were tens of millions in the camps (not all at the same time).
They were taken from the ghettos to extermination camps, where they were killed.
Ghettos preceded concentration camps. Concentration camps appeared during the Nazi era in Germany. Ghettos were present in the largest cities in Germany (and other large urban areas in other countries) well before that.
Life in the ghettos was not only restricted and confined, but eventually, everyone in the ghettos was carted to concentration camps.
They were sent to ghettos prior to the Concentration Camps...
Internment Camps were camps created by the United States government to house Japanese-Americans during the Second World War. Japanese-Americans were removed from their homes and forced into camps, for the government feared some were spies for the Japanese Empire.
ghettos, concentration camps, and death camps
The Jewish ghettos were sections of the city that were allocated specifially for Jewish housing.
In practice, that is exactly what the ghettos set up by the Nazis were.
