1. Not all Japanese were relocated. Japanese on the west coast were relocated away from the coast as signaling to off shore ships was occuring.. There were some valid concerns.
2. Japanese living in the interior of the U.S. were not sent to camps.
3. One of the purposes of relocation was to protect Japanese. I wasn't alive at the time so I can't speak to this.
4. This was an unfortunate chapter in our history, but I don't believe it is the evil that it has been made out to be. Californians who lived through the war have said that there was concern about spying and sabotage, and there were real threats to the Japanese who lived here.
Please let me know if anything I've stated is not true, as I am always open to being set right.
A similar issue exists today. IMO we have every reason to use racial profiles to select individuals for extra examination at airports, Universities, etc. We should not, however jail everyone with swarthy complections and Middle Eastern names only on the strength of their name and complection. If a person, an individual, is an Islamic Militant advocating our destruction -- jail or boot them now. But if we sink to their level, we lose our civilization.
I know a family who owned a swath of land extending to the Pacific, roughly 10 miles deep along Wilshire on East past Little Tokyo.
Today this land is worth several billion dollars.
While they were held captive in a variety of camps, 100% of it ended up in the hands of wealthy white Californians, there being no wealthy black Californians at the time.
They recovered 5 cents on the dollar of loss and purchased a very large chunk of Anaheim. Part of that farm is now the Disneyland parking lot.
Disney is the only white man who ever paid them a penny for any property.
