Part of Sicily is weird, but there was actually a small movement there during WW2 wanting the whole thing to become a US state.

In Sicily, the Party of Reconstruction was one of several Sicilian nationalist and separatist movements active after the downfall of Italian Fascism. Sicilians felt neglected or underrepresented by the Italian government after the annexation of 1861 that ended the rule of the Kingdom of the Two Sicilies based in Naples. It claimed 40,000 members in 1944, and campaigned for Sicily to be admitted as a U.S. state.
