First of all, I don't take in very high regard the extreme-left wing views of the South African state. Their constitution guarantees free health care, but doesn't implement it and has a government that wanton takes property to give it to the 'poor' who subsequently and obviously, because they do not have experience or training cannot manage the land, cannot afford to buy seed, tools and thus the land goes to waste. Apartheid is bad, the solution South Africa implemented (borderline communism) is worse.
By declaring Israel "Occupied Palestinian Territory" the whole treatise goes out the window. Israel is an established state, not an occupied territory. As I said, Palestine, as a country, never existed. The "State of Palestine" was invented by the UN in 1947 as a response to Arab pressures to finish wiping out the Jews after the holocaust and this state has never been recognized by the US or the UK.
It was British, before that Ottoman Empire, before that Roman Empire and before that "Israel" (a primarily Jewish territory which was pretty much dominated by empires throughout history).
To further destroy the first pillar, Palestinians can live free in Israel, Israel does have the right to set its own immigration law. These laws are very similar to the US's, if you are born of a US citizen, even abroad, you can always return because you are a US citizen - but we don't call the US an apartheid state because they accept foreigners born of US Citizens but not Mexicans.
To destroy your second pillar: The UN in its establishment of the State of Palestine, defined those regions, after the UK had already established Israel. Israel voluntarily gave and has actually given more land to the Palestines since. The Palestines won't be happy though until, as is explicitly stated in the Quran and by Hamas and by the PLO in the past and by Yasser Arafat and every group there is in Palestine to eradicate the Jews from the world. Israel has sufficient firepower to simply invade and take over the areas, and they have in various Israeli wars demonstrated their capability to even take Jordan and go as far as Egypt, but they simply don't.
As for the third pillar, there is no evidence of state-sanctioned torture of Palestinians within Israel.
I had walked from one apartheid state into another. No one needed to tell me that. - as Adam Sandler puts it "Earnest, not a Jew" - The fact however that you see a difference does not mean the state of Israel is to blame. Palestine, as I said, has been self-ruled and has the power to make its own elections, its own decisions, its own laws. They haven't had elections in a decade since the first and only election they had established a dictatorship.
Secondly, history shows that Jews made up 7% of the population of Israel in 1914. with Moslems comprising the largest segment of the population. <- Fixed that for you. And yes, Jews make up a minority in Israel, Palestinians and Christians get to be in their government too.
The reason the number of Jews in Palestine increased was the Balfour Declaration during the First World War which allowed for "a national home for the Jewish people" in Palestine in exchange for support from the Zionists.
Yes, to the first part, no to the second part. The British area was given to the Jews during the Balfour Declaration, the primary goal was to return Jews their land which the Romans had taken and dispersed the Jews that live there, the second reason and primary reason for the British was to give control of the "holy sites" at that time under hot contention from all Christians, Jews and Muslims to the League of Nations. This was done to preserve the sites during the war and prevent a holy war. Zionism came later and was a side effect.
