I might add a little perspective to Mr Yamada's sentiments.

Relatively speaking, the Japanese-American Internment was a walk in the park compared to how American POW's were treated by Japan in the Phillipines during The Bataan Death March.

"The 60 mi march was characterized by severe physical abuse. It was later judged by an Allied military commission to be a Japanese war crime.  They were beaten, and they were starved as they marched. Those who fell were bayoneted. Some of those who fell were beheaded by Japanese officers who were practicing with their samurai swords from horseback."     https://en.wikipedia.org/wiki/Bataan_Death_March

Apologists are quick to condemn America for interning potential enemy combatants during WWII but conveniently neglect to mention the atrocities committed by our enemies. 

 It would have been a very different story had a handful of assimilated Japanese immigrants hijacked an airliner and flown it into the Empire State Building.
