War World USA The Residents Japanese
Michelle Malkin, a nationally syndicated writer, has published an extensive analysis of this event, which has stirred a lot of controversy. Her assertion is that there were good, valid reasons for the internment. Despite "research" to the contrary, there apparently actually quite a number of Japanese agents among the Japanese population of the West Coast.
I haven't studied this very extensively, and I am not an apologist for the decisions of a past generation, but I think there is much more to the story than is normally reported. I honestly don't know how I would have acted in the same situation, except that I do oppose anything similar after 9/11 regarding Arabs. I think that in situations such as the post-Pearl Harbor days, that national security does need to be carefully considered, and that profiling is vital, but that doesn't normally justify wholesale imprisonment.
One story that I know Mrs. Malkin tells is about a Japanese pilot who crashed on one of the remote islands in the Hawaiian chain. Some of the Japanese residents of the island, although patriotic citizens of the Hawaiian nation (at the time), helped the pilot to evade authorities, including helping with the murder of some of their fellow Japanese residents. Eventually, the pilot was killed by one of the other Japanese residents, before the island authorities were able to find him. However, if I remember rightly, it was in self defense.
