The government could not intern the Japanese Americans in Hawaii because they were high percentage of the population. It was not too hard to round up the Japanese Americans in California. My father watched them getting loaded onto trucks on Rodeo Boulevard in Los Angeles with one suitcase per person. It really bothered my father, and he was no liberal.
Actually, I meant the mainland United States, the focus seemed to be only on the areas where the US could be hurt, inland.
To my knowledge, there was only one high-ranking politician who spoke out against internment of Japanese-Americans in concentration camps: Governor Ralph Lawrence Carr, who said:
“If you harm them, you must harm me. I was brought up in a small town where I knew the shame and dishonor of race hatred. I grew to despise it because it threatened the happiness of you and you and you.”

He lost his next election.
