What were some reasons against the Japanese internment of 1942?

Answer 1

I can't think of any reason not to have distrusted anyone in the Japanese community at that time, since it quickly became known that valuable intelligence was passed back to Japan from Pearl Harbor during the December 7,'41 sneak attack, by simple telephone calls back to their homeland from some Japanese residents nearby.

Any Military History reader can tell you of various Japanese plans and actual attempts to bomb the North American mainland. Any telephoned reports, confirmations, or plain gossip and local news etc. would have been a valuable asset to our enemy during the war. The German community in North America was actively trying to discourage Americans and Canadians from thinking about contributing to the war effort of the British people, early in the war. The Japanese sneak attack awakened North America to the possible and highly probable danger from within.

One apple can spoil the whole barrel, we like to say. Thus the wartime internment was necessary for national security, in order to save North American lives.

The hard lesson the British civilian population learned, was that loose lips actually sank ships during the war.
