Is it possible, with a POD after 1 CE, for the Jewish Diaspora to never occur (i.e. Rome never deports the Jews en masse, not "no Jews outside of Judaea"), and if so, how? Bonus points if the Great Jewish Revolt still happens/the Temple is still destroyed, and Judaea is still annexed to Rome.
How does Judaism develop without the Diaspora? How does Christianity change? Does this impact the historical trajectory of the Empire to any substantial degree?
