The circular analogy is complete, grasshopper. We couldn't trust the Nisei to raise their hands against the Emperor just like we can't trust Muslims to raise their hands against Islamo-facists.

Again, you don't make sense - We could ( and did ) trust them to fight beside us against the allies of their Emperor.
We would not ( and did not ) put them in a position where they might be mistaken for enemies disguised as our soldiers.
...Or put them in a position where the prejudices of those around them might cloud the mission.
American soldiers of Japanese decent were not singled out by their religion, but simply by their names, or background, or facial characteristics
By your faulted reasoning, only those Shintoists should have been singled out.
