what was the Constitutional basis for the internment of the Japanese during WWII?

Question

It is about Japanese Internment Camps and World War 2

Answer 1

There was none. Like many of the measures taken during war time, it circumvented the constitution. Other examples -- Alien and Sedition Act, Espionage Act, Sedition Act, Patriot Act.

Answer 2

It was a wartime measure for security reasons. Not everything the government does is directly derived from the Constitution, especially in a crisis.

Personally I find it ridiculous that we feel obliged to compensate these people at this point. Considering that a harsher government would likely have tortured and killed many of them, they really didn't fare that bad considering the times.
