Spread some knowledge about this whole issue my way cuz from the tiny little bit that ive read about the issue is that the jewish people were given a certain amount of land after WW2 and then from that point on there was forced occupation.
The British had promised to parcel lands in that region for a Jewish state in 1917 via the Balfour Declaration. Jews migrated to the lands the British controlled as apportioned to the British from the League of Nations after the dissolution of the Ottoman Turkish Empire (which had previously ruled the region) after World War I.
They didnt really buy most of the land like i said. Jews were coming to Palestine in a trickle, picking up pace nearing WW2 and after WW2.
Actually, Jews were coming in at such a pace that the British put a quota on Jewish immigration before World War II so that Jews could only comprise 33% of the Mandated land's population, in the McDonald-White Papers (which also parceled off an Arab state of Jordan and barred Jews from migrating there). That agreement consigned a whole hell of a lot of European Jews to concentration camps. And regardless of how Jews got the land, whether buying it or renting it from British owners, none of the Jewish immigrants displaced a single Arab during the period.
However, they were a bit lazy and a few odd declarations later, they managed to piss both sides off. The UN stepped in and "divided" the land (what they intended was the same as the British' original idea. 1 country, 2 peoples).
The original idea was 2 countries for 2 peoples, with each ethnicity comprising a majority in their country. The UN Partition Plan would have accomplished this, with a 90% Palestinian majority in a contiguous Palestine and a 55% majority in a contiguous Israel.
Both parties thought the solution sucked big hairy balls and the Jews in turn proclaimed the nation of Israel.
That's not exactly a fair way to put it. While the Jews weren't terribly fond of the Partition Plan (they were 33% of the population, got 13% of the land and didn't get Jerusalem), the Jews accepted the Partition Plan, which allowed them to proclaim their state.
The Palestinians and the Arab World didn't recognize the Partition Plan, launched the 1948 war to eradicate Israel and lost. After a few more failed attempts to destroy Israel, now the Palestinians want the Partition Plan's borders for their Palestinian state, despite having never accepted the plan in the first place.
