Except that wasn't what was going on. The people who could be identified 
as "German" were looked over on a case-by-case basis to assess whether 
they'd be likely to support the German war machine, and a fairly small 
proportion of them were interned. We couldn't sequence human genome 
until about 2003, and it isn't all that helpful. I've had it done and 
while my ancestors mostly came from England one of my 
great-grandmothers, while born in England, was a member of a family who 
had come over from Strasbourg, so I'm one eighth Rhinelander (and it 
does show up clearly in my genome).

That didn't matter. It was their sympathies that mattered.

That didn't matter either.

There wasn't any propaganda content. It was just anxiety about 
loyalties, and probably not confined to the president. Franklin 
Roosevelt was several generations away from the drug dealers and slave 
traders. He was a fifth cousin of Theodore Roosevelt, but his wife 
Eleanore was Theodore's niece.

And any anti-German prejudice he might have had didn't stop him from 
taking Einstein's advice about the atom bomb, which does seem to have 
been error-free.
