Conclusion: Israel has got the greatest chance of eradicating Palestinian people out of the Israeli soil. The reasons are the following.
West European countries and the United States are reluctant to intervene in the problem about Palestinian people living in their autonomy in Israel.
Israel outperforms Palestinian National Authority in the military force.
Western European developed countries and the United States want the good term and tie with Israel. Without Israeli help, they would have difficulties in exerting their force in the Middle Eastern area.
