Regarding Hawaii's Americans of Japanese descent, they WERE incarcerated by state and federal agencies without trial. They were incarcerated in mainland camps and I personally am aware of several cases where the male head-of-household was removed from the family and no communication occurred to wife or children for years (while the dad was incarcerated without any charge). This had the effect of debilitating churches and businesses in Hawaii also.I don't doubt this, but from what I've read the incarceration was not universal as it was on the west coast of the mainland. This in a place where there was a higher percentage of residents of Japanese descent, and many more potential espionage/sabotage targets.
People sometimes forget that those who come to America are inherently different from their counterparts who stayed behind in their original countries, and they live here for a reason.

Yes, you are correct. It was not a wholesale slaughter of the ethnic Japanese community. In fact, in Hawaii the suggestion of extending Exec Order 9066 was made and quickly dismissed by military commanders. Because the ethnic Japanese in Hawaii were so instrumental in homeland defenses, the idea of sending them out on valuable passenger vessels was ridiculous. The US needed those naval vessels for ordnance and supplies, not to give passenger space to a bunch of cane field workers who were travelling the oceans for no real reason.
