Nah, there are a bajillion ways of making pizza in Italy, it’s just that the thick and soft one is never round, but even the round one can be thicker or thinner depending on the local preference. It would actually be interesting to find out if the American style of pizza was influenced by a traditional Sicilian pizza called “sfincione” which is still very popular, given the strong Sicilian component of Italian immigration in the US.
