Did the leader of this hypothetical NYC example state the following?
Addressing the Mapai Council the following day, Ben-Gurion declared: “From your entry into Jerusalem, through Lifta, Romema… there are no Arabs. One hundred percent Jews. Since Jerusalem was destroyed by the Romans, it has not been so Jewish. In many Arab neighborhoods in the west one sees not a single Arab. I do not assume that this will change… What had happened in Jerusalem… is likely to happen in many parts of the country …in the six, eight or ten months of the campaign there will certainly be great changes in the composition of the population in the country.”
