The Italians hate Americans
I lived in Italy for 5 years and did not get that impression. In fact, I was in Italy (Sicily) during this whole fiasco.
I think it’s more the official world of Italy that hates Americans, rather than the average Italian. But that’s true of Europe in general, actually.
Tens of thousands of Americans gave their lives to save the Italians from Nazi occupation. To think that we could have spared their lives had we left those ingrates to live under Nazi rule.
