How would you react to a solution proposed by the Palestinians that took 10% of Israel?
Again with the assumptions. Let's look at history first... no, not all the way back to Biblical times - modern history.
First of all, the West Bank was captured by Israel in a defensive war in 1967 from Jordan (defensive as stated by the UN at the time). Jordan, for that matter, "acquired" the West Bank illegally, as part of their offensive war fought against the newly-formed state of Israel in 1948. Before that time, the area was known as Judea and Samaria.
So, between 1948 and 1967, Jordan occupied the "West Bank" - an occupation which hardly any other nation recognized as legal, not even by any other Arab nation.So who did the Judea and Samaria belong to before they were occupied? Going back a bit further, the Turks (Ottoman Empire) had control over the entire region until 1917, when they lost in WWI to the Allies. They gave up control over the territory, and the Allies decided to make countries out of the area. Britain's Lord Balfour recognized the ancient Jewish right to the region and proposed to allocate to the Jews the area equivalent to
modern-day Israel and Jordan (minus the Golan heights IIRC). The League of Nations had second thoughts and split off the area we know as Jordan into its own country, the Hashemite Kingdom of TransJordan in 1922, but recognized the Jewish homeland as an area that
included Judea and Samaria (the "West Bank") - which was reaffirmed by the UN after WWII.
When the British mandate ended, UN General Assembly resolution 181 recommended splitting the area up yet again, into two states - a Jewish one and an Arab one. The Jews accepted the proposal and went on to establish the modern State of Israel. The Arabs refused and launched the 1948 war to destroy the newly-birthed Jewish state (btw, according to the Wikipedia, "In 2011, Palestinian president Mahmoud Abbas stated that the Arab rejection of the partition plan was a mistake he hoped to correct"). This left resolution 181 with no legal authority. When the 1948 war came to a halt due to reaching a ceasefire, the lines demarcated by the fighting were what we currently call the "borders" of the West Bank and Gaza strip. The Arab leaders at the time, being consistently bull-headed, insisted that these lines have no political significance. Let me restate that in case you missed it:
what we call the "1967 borders" are not from 1967, but from 1948, and were never recognized as international borders. This left those areas as
disputed territories, not "occupied territories".
To recap: Israel's presence in the "West Bank" is the result of a war of self-defence (1967). These areas were not occupied territories, since they did not legally belong to any nation up till then, but disputed territories. These territories were recognized as part of the Jewish homeland internationally, and since resolution 181 has no legal standing, they are at best/worst (depending on your POV) still only disputed territories, and thus the presence of settlements therein is not illegal.
So, to answer your question? The Jewish people reacted to a proposal by the League of Nations / UN to take away huge percentages of their homeland with a
positive - so be it, we'll take whatever we can get after the horrors of the Holocaust. The Arab nations lost subsequent wars, and are now whining about it.
