Following WW-II the state of Israel was declared in the area formerly held by the British under a UN mandate in the area between the Mediterranean Sea in the west, the Jordan River in the east, the Sinai Peninsula (with the adjoining Gaza Strip) in the south and Lebanon/Syria in the north. This was the result of a UN resolution which divided that area between the new state, and a territory allocated to the non-Jewish residents of that area, which decades later became self-declared as the Palestinian people.

Several decades and several wars later (the first of which was started by several surrounding Arab states with support from the local Arab population, all of whom rejected the division plan passed by the UN) Israel covers a larger area, and controls the West Bank and East Jerusalem, home to millions of Palestinians. Israel also controls all but the southern border of the small Gaza Strip, home to millions more Palestinians.

Israel was the historic home of the Jewish people starting over 3000 years ago, and has had a constant (small) Jewish presence throughout the millennia, despite several ancient empires conquering the area and expelling much of its Jewish population, driving them into multi-millennial exile.

The above being the case, the "relocation of the Jewish people" of Europe following WW-II was nothing more than a home-coming of an ancient people, forcibly expelled from their land in ancient times. No relocation anywhere else would have been just or acceptable. In fact, many countries around the world actively limited the influx of Jewish refugees from Nazism.

While the above is widely accepted in Israel and among its supporters (as well as most main-stream historians), it is most definitely *not* accepted by the Palestinians, the Arab states, and their supporters world-wide, who see the establishment of the State of Israel as a national disaster for the Palestinians, the so-called Naqba. To this day there is a ceaseless struggle between the sides, with many facets - propaganda/education, civil unrest, terrorism, armed resistance, etc. on the Palestinian side, with military/police response on the Israeli side, including an effective siege closing off the Gaza Strip to all but minimal shipments of critical relief supplies, a separation wall between the Palestinian population of the West Bank and Israel (much of which is sited on West Bank land and causes immense hardship for many Palestinians, as do hundreds of Israeli road blocks and check-points), etc. The situation is dire for the Palestinians, and is no cake-walk for Israel. Peace-making efforts have been started, stopped, restarted, stalled, etc. since before the 1993 Oslo Accords, and are not expected to bear positive fruit anytime soon, to the sorrow of all reasonable and peace-seeking people everywhere.
