Where are the Arab Jews now? Entirely assimilated into the nation of Israel. And where are the Palestinian Muslims? Those who left, voluntarily of not, are largely living in camps in their Muslim "host" countries, supported by international handouts. Who got the short end of the stick? Almost certainly the Palestinian Muslims. And ho stuck it to them? There are many candidates for that, but Israel is not very close to the head of the line.

Israel was entirely responsible. The countries to which the Arabs fled are very poor countries that are not able to support large influxes of people, and they also recognize that it is illegal under international law for Israel to not repatriate all of the refugees who left there during 1948 and 1949, and these countries know that they are not in any way obligated to absorb them into their populations.

Israel also has many internal refugees. Arabs who were driven from their homes and land during the ethnic cleansing, but who never left what is now Israel. These people have not been allowed to return to their homes, even though they never left the country.
