I disagree, internment was right.
To say it was wrong is to assume that none of them might have helped the enemy in some way had they not been. But we will never know that.
It’s only looks wrong in retrospect now because nothing did happen.
There is a large contingent of voters who think YOU should be interned because you’re a Tea Party / climate change denier / right wing / etc type, so obviously a threat to domestic tranquility.
It grossly violates core American principles. Don’t “burn the village to save it”.

It is certainly wrong to say that none might have helped the enemy. At least 3 did directly following the attack on Pearl Harbor.
It looks right to me because it was Common Sense, which unfortunately is not so common anymore.
