[Former Proud Canadian]

To get this discussion back on track, the internment of "enemy aliens" has happened several times in the United States. The most famous example is the civil war when the much venerated Lincoln suspended habeous corpus and jailed politicians, newspaper publishers, just about anybody who opposed his war effort. During WWII, of course, internment camps housed Japanese, German, and Italian sympathizers in Canada and the US. There is precedence and it can happen again.

Not just Japanese "sympathizers," of course...

To try to tie two discussions together, "ethnic" Japanese were imprisioned for no reason other than their background. Citizens, some second, third and fourth generation Americans who were fully "assimilated" (which is a fairly ridiculous notion when you think about fourth generation American families in a country full of immigrants) and still seen as different.
