That was indeed the logic then. Keep in mind though that the internment was based on 'race' and 'ethnicity'. This action is based on citizenship and it's a job limitation not a forcible relocation into an open air prison.

I think the same method might be used again in a future conflict with China, when the question of life and death becomes serious. Not saying that I LIKE it, but I think it is at least plausible, and with a non-insignificant (note the double negation) possibility.

Man, if there were only something more reasonable... something in-between letting them spy at will and concentration camps. Hmmm, maybe we will think of something eventually.

Ok, then let them spy continuously I guess and then carry the know how home. Even countries openly hostile to you.

I mean it is unfair for sure but it's not your given right. If for example Chinese are literally breaking their law when they refuse to spy what else can you do?
