What do you think about the internment of the japanese in the USA in WWII?

It wasn't Japanese businessmen and tourists that mostly comprised the interned, but US citizens.

It was in the same ball park as those in Nazi Germany put in concentration camps for no better reason than the regime deemed them as some kind of threat to the rest of society - exactly the same reasoning used by the US government at the time.

In part the reaction was understandable: the Japanese nation sent many 'travellers' and 'businessmen' and 'students' to countries on the invasion list (Indonesia, Malaya, Hong Kong) as spies. In Japan the army had tightly controlled the education system from 1910, and crushed democracy in the late 20s and early 30s... all Japanese were supposed to considered themselves as 'the Emperor's children', and the Japanese military was uniquely successful in this. Compared to Japan, Hitler's Germany was full of dissidents and rebels and free thinkers. There was NO Japanese anti-war movement. There was NO underground resistance.

The USA on 1941 was both naive (innocent in thought) and with the onset of war, paranoid. The US was right to fear Japan's underhand approach to warfare, but they were very mistaken about the specifics, facts and realities. So the oppression of Japanese Americans was misplaced, they were almost all loyal or, at least, had not much interest in helping Japan.

Though understandable, in progressive countries we must hold ourselves to a higher standard of behaviour so it is right and just that today America is ashamed of its treatment of interned Japanese.

Like most Germans, you English is excellent.
