world was ever compensated or repatriated by their former countries of residence—to no objection on the part of Arab leaders—a precedent has been set whereby it is the responsibility of the nation which accepts the refugees to assimilate them. Although Israel accepts the right of the Palestinian Diaspora to return into a new Palestinian state, Israel insists that the return of this population into the current state of Israel would be a great danger for the stability of the Jewish state; an influx of Palestinian refugees would lead to the destruction of the state of Israel. According to Efraim Karsh the Palestinians were themselves the aggressors in the 1948–1949 war who attempted to "cleanse" a neighboring ethnic community. Had the United Nations resolution of 29 November 1947 recommending partition in Palestine not been subverted by force by the Arab world, there would have been no refugee problem in the first place.

Huge numbers of Palestinians were also expelled by their leadership to prevent them from becoming Israeli citizens and in Haifa and Tiberias, tens of thousands of Arabs were forcibly evacuated on the instructions of the Arab Higher Committee.

Suicide bombings have been used as a tactic among Palestinian organizations like Hamas, Islamic Jihad, and the Al-Aqsa Martyrs Brigade and certain suicide attacks have received support among Palestinians as high as 84%. In Israel, Palestinian suicide bombers have targeted civilian buses, restaurants, shopping malls, hotels and
