During ww1 a strong anti-German sentiment grew in the US forcing the germans to assimilate. During ww2 Japanese Americans were forced into camps. How come none of this happened to the Italians?
It did. Assimilation occurred on a wide scale, and it continues today, often though gentrification.
And Italians were placed in internment camps, as were Germans. Neither were on as large a scale though, as the US’s main adversary and concern was the Empire of Japan.
