If I recall the Germans that were held were mostly adult aliens.
Many of the Japanese were citizens and the entire family was interned,including children.
That may be true (haven't checked), but I was just pointing out that the Japs weren't the only ones interned.
Japanese-Americans were locked up if they had "one Japanese grandparent," and lived west of the Mississippi, except on Hawaii. German-Americans were only locked up individually and on specific charges. Huge difference.
My book, Manzanar, gives the history of those camps. Had German-Americans have been locked up on the same basis, I wouold have died in one of those camps in 1943 -- the medical facilities at those camps were inadequate to deal with a premature baby who had one German grandparent.
Mears' description of the difference is correct.
