ok, lets go over some things here:
1.) Written by jews:
9/11 Conspiracy theories blaming America are written by Americans, that does not make them true.
2.) They "had" to leave because they had no work. So sad. Thats not the fault nor dutyN of Jewish immigrants to provide them jobs. If they wanted investment in the region they should have asked the government, ie the Muslim Ottoman Empire.
3.) NINA signs deal with how the rest of the world was the same way and its not like Palestinians suffered some grave injustice.
4.) Palestine (the Mandate) is not Palestine (the West Bank and Gaza), It included modern day Israel, the West Bank, Gaza, Jordan and large swathes of what is currently Saudi Arabia (after Jordan sold them the area for a port city).
The Mandate of Palestine was Jordan. 90% of the land of Palestine went to Palestinians (who renamed themselves Jordanians).
Then Israel became a state, and Jerusalem (despite being Jewish Majority) was to be its own region. Then Jordan tried to annex and occupy Jerusalem. This is why Israel refuses to "give back" Jerusalem, it never was Palestinian and is a Jewish majority city.
4.) Harry Truman
Truman was not a fan of Jews. His support of Partition was based on 2 things, public support shifting after newsreels of British assaults on Jews in Palestine, and fear that the Soviet backing of Israel would jeopardize the safety of the middle east by creating a soviet sattellite state unless America switched its position to be Pro-Israel.
The quote you attribute seems dubious, as a southern politican going on a pro-Jew policy would only cost him votes, especially if he did so publically. He was on shaky enough ground after desegragating the Army.
Now, to answer your Questions:
1.) Let's consider the Jews bought all the land they are presently occupying, why don't they leave the rest of the land to the Palestinians? Why still build more settlements on land they do not own??
Most settlements have been from Far Right Extremists, those settlements have been systematically torn down, and continue to be done so. There are upsurged where occassionally a far right party wins a minority government (briefly).
Most of the other settlements are in Jerusalem. This causes a large headache. They aren't illegal settlements on Paletine, as Palestine has no right to Jerusalem. Jerusalem was an occupied territory under Jordanian/Palestinian occupation. And if you asked Jerusalem in a vote, they would allow they settlements, as they have always favoured merging with Israel, being forced to remain independant by the UN, and then invaded and annexed by Palestine.
2.) We need to establish who owns the land in Gaza and the West Bank.
On a local level, the citizenry. That being said, while I own property, that property belongs to Canada as well and I can't sell it to North Korea.
On a larger level it was Egypt and Jordan. Both have made peace with Israel and declined any further claims on either Gaza or the West Bank.
So Gaza and the West Bank are occupied territories (somehow) but that aren't actually being occupied FROM anyone. They never were their own state..so they aren't "occupied palestine", they are just kind of in Limbo. Which is the problem, previously they were occupied from Jordan and Egypt...now they aren't from anyone..so who do you give them back to? They aren't viable states and Israel has stopped occupying Gaza (though it still provides them with free electricity and supplies). If Gaza declared independance nothing there would change except Israel would stop supplying free stuff.
3.) My upset is over how the Palestinians are treated by the Jews, by America and by the rest of the world.
Yet you aren't upset by how Palestinians are treated by other Palestinians? Palestinians suffer worse and more at the hands of other Palestinians than they do by Israel (which is a fifth muslim btw, and the Muslims in Israel are also soldiers and also involved in actions against palestinians)
The world treats Palestinians as above all other humans , all other suffering in the world. A bad day in Palestine is still a good day in many warzones around the world.
The better question would be, why does the world hate Africans and Asians but love Palestinians?
4.) Why would Jimmy Carter get upset about the situation and write an entire book about it, IF the Jews really owned all of Palestine through legal purchases?
The guys a nice man, but he's pretty daft. Now there are legitimate greivances, namely the current problem with the time Palestinians have been in Limbo.
Israel is still occupying them, but it can't annex the region and it can't give them back because no one will take them. It offered the Palestinians the state they wanted with the conditions they wanted, but Palestine turned it down. Because Arafat new he'd get shot if he made peace (just like the Egyptian President who made peace with Israel).
What should Israel do exactly? It can't set them as independant, it can't give them back to their host country and it can't annex them, all thats left is occupation.
5.) And why would England give the land to the Jews, if they owned it already?
Again, England didn't give away the property rights of Individuals, it drew the national boundries. If Canada gives Alberta to the US, that doesn't mean everyone in Alberta's house is now owned by the US government, it means Alberta would fall under the Jurisdiction of US laws.
Likewise England gave Israel the land in the sense that Israel was now the government of that land. Individual properties weren't awarded (other than previously government owned land)
6.) And why would the UN draw up a sketch and designate it to the Jews, if it was already all theirs?
Again, the Jews owned the physical property, they were awarded Sovereignty for a government, they are two different things.
7.) I understand that the Jews started buying land from about 1840 into the 1930. By 1930 the Ottaman empire was already broken up, so whom did they give the money to for the land?
Again, this is the same confusion. When they bought land, they were buying from the individuals who owned it. This is no different then when you buy a house in Canada, you buy it from the owner. Even though you now own property in Canada, you didn't directly buy the land from Canada. They bought the land from individuals. The government changed from Ottoman to British, but that just changes who they paid taxes too.
8.) If the Palestinians are only poor peasants and farmhands, then who owns the land they are working and living on now?
Again, thats a case by case basis. Some of them may own the land, some of them are renters (in apartments and whatnot). The West Bank was part of Jordan (its called the West Bank because its the West Bank of the Jordan river, the river Jordan is named for), so the land had evolved from 1840's to the 1960's in the same way as most of the world, and average middle class people own alot of the land.
But again, thats owning the property rights, not "owning" in the sense of what governments laws apply on that land.
