@cicerone imposter,
A little known twist is that over 10000 GERMAN-AMERICAN citizens were held in various interment camps throughout the nation. My parents neighbors were children of citizens who were kept in the Gloucester NJ interment camp. The guy was a fabrics engineer and worked for a developer of parachutes. He was a "person of interest" as a potential NAZI just because he was of German extraction.He moved to the US after WWI and left Germany alone.
There were 2 such GERMAN camps in PA because there was a hysteria that the famous "Horseshoe Curve" was an important target for bombing by "Sleeper cells" of German AMerican citizens who were separated from germany within a generation during the Nazi years.
Iwas told that we also had some Italian American camps but that the "Mob" was already a target of the FBI and as such was being watched more closely. Im not familiar with the Italian story so Ill yielld to anypne who has better information.
My mom had kept newspapaers of home-side stories that affected our little communities of Allentown and Kutztown Pa during WWII.
