Italians also.
My great grandfather came to America from Italy in 1913. He worked as a coal miner and small farmer in central Illinois When the war started, the FBI came to his house and seized a table radio with a shortwave band his kids had given him for his birthday and that he used to listen to opera, along with an old shotgun and a pair of binoculars.
He sent two sons to the war. One came back with his insides messed up after another guy jumped feet first into the hole where he was taking cover during a Japanese air raid. Then the military lost track of him and reported him to the family as M.I.A., until a couple of months later he turned up in a hospital stateside. The other one came home in a box, killed on the Cotentin penninsula seven days after D-Day.
