Very interesting book on the subject with lot of source material included as scans. The book summary there is worth reading.
Short summary - we knew a LOT was going on, but didn’t want to reveal we’d broken their codes. So FDR made the call to inter everyone for the duration. It was not just the terrible call it has been made out to be, it was a very tough call.
BTW that link is hard to find with an Amazon search. The only way I can find it is by searching my order history. Make of that what you will.

I have a speculation I posted today about the internment. It is at:
Atomic Research, Pearl Harbor and Japanese Internment Eighty Years Ago

All my life the regular media liars told me that we rounded up all the Japanese because America is a racist country. I had never heard of anyone but Japanese being rounded up and put in camps.
Then several years back I stumbled across the fact that we did indeed round up Germans during World War I and put them into internment camps.
So yeah, once again I found out the media liars are liars.
