One way of fulfilling requirements for some scout ranks is to partake in community service programs, so perhaps they’re running errands for their community by hanging this sign up. It’s a haunting image.
They likely considered themselves Americans (because they were), and did not realize that even third-generation American-born citizens would be considered "aliens" and "enemies" and sent to the camps.
I think I figured it out: If all non-citizens are aliens, then aliens of enemy nationality is a subset of that group. It's defined by aliens that are from a country that is designated as an enemy country. So French aliens are not included, but German and Japanese aliens were.
No, they didn't care about citizenship or where you were from.

They also didn't really care about German or Italian ancestry, there were millions of such people and almost none were imprisoned. Nearly all Americans with Japanese ancestry were imprisoned, and most were American-born citizens.
