What Really Is Happening, BIBLICALLY, With the Palestinian vs. Israel Conflict:
First one must know a bit of history of how things got like they are today in the holy land.
1.
After the unbelieving Jews rejected Lord Jesus Christ and The Gospel in Jerusalem, and had Lord Jesus crucified, Jesus told them their house would then be left desolate (Luke 13:35). Then in 70 A.D., God brought the Roman army upon those Jews led by the Roman general Titus, and destroyed Jerusalem, and the temple, and scattered the Jews out of the holy land.
The unbelieving Jews then roamed through the nations like gypsies, being cast out of Christian nations because of how they operated, and refusing to convert to Jesus Christ. They kept their Israelite heritage which God had prophesied, which is why they were so controversial among the nations. And they still looked to return to their original homeland, the lands in the middle east where Palestinians had by then taken over completely for centuries.
Philistia (Palestine) existed on the Gaza strip only (coastal side west of Israel), which the Palestinians dwelt there even during the height of the old kingdom of Israel. So the Palestinians do have a 2,000+ year history in that land, even though ever so small compared to all the territory which God had given the children of Israel to conquer from the Canaanites, Hitites, Amorites, Jebusites, etc. Palestine today claims also the territories east that border the Jordan river, but those lands originally were given to Israel to conquer when they first crossed into the land of Canaan when crossing the Jordan, and they were part of the old kingdom of Israel under David and Solomon.
Since the unbelieving Jews were cast out of the holy land, they have since wanted to return, and re-establish old covenant worship with a stone temple, which the orthodox Jews even to this day believe they are still bound to by God. They still reject Jesus of Nazareth as Messiah, and instead are waiting for their Messiah's coming to rule as King of Israel. They understand how God per His Word had promised the holy lands to their fathers and their children, so they are not going to ever be deterred away from giving up those lands.

In 1917 the world stage started changing for the scattered Jews. The British government issued the Balfour Declaration declaring a national homeland for the Jews in Palestine. It was delivered to Zionists in Great Britain and Ireland. Jews had crept into the British government in order to create these declarations in favor of the Jews (See Herbert Samuel, Lord Rothschild). WWI had begun in 1914, and Britain had taken control of Jerusalem from the Ottoman Turks. So this plan for a national homeland for the Jews was already on the drawing board during WWI by Britain. More Jews starting returning to the holy land setting up temporary shelter. During the WWII holocaust a huge flood of Jews returned which is no doubt when the Palestinian Arabs saw the potential of their population dwindling compared to the number of Jews coming into the lands.
Britain at that time supported the Jews coming into the holy land, giving them more territory than the Palestinians, even though the Jews were a minority population at that time. This is when the fighting started between the Jews and Arabs over the land. The Arabs had been in those lands for centuries, and they certainly were not going to give up the land either, even though the majority of it originally had been given the children of Israel by God.
The fighting got out of Britain's control, so Britain's military left the holy land. Savage massacres by both the Jews and the Arabs would happen upon innocent peoples on both sides. Then in 1947 the United Nations stepped in and created an Israeli state, and divided up the territories, giving the Arabs control of part of Jerusalem and the Temple Mount. To this day the U.N. controls the land borders for both groups.

Both the Arabs and the Jews tend to blame Great Britain for creating this situation, but that is not a fair assumption, simply because political Jews within the government of Britain had a strong hand in creating the Zionist documents and political meetings initiated within the British government. The truth of the matter is that the Jews were behind it all along, yet, we still have to consider their operations were moved by a higher source, God Who had previously promised Israel those lands from the river Nile all the way to the border of the Euphrates river (Gen.15:18-21).

At the same time, a deep-seated jealousy within the Arab population exists against Israel. The Arabs are descendants of Ishmael, the first son of Abraham but with the hand-maiden Hagar, the servant of Abraham's wife Sarah. God had promised Abraham that His covenant and Birthright would be established with Abraham's son from him and his wife Sarah, not with the bondservant Hagar who was of Egyptian heritage.
When Hagar had Ishmael, she became haughty acting in front of Sarah, because a married woman that was without child was seen as cursed in that time. Sarah asked her husband Abraham to cast Hagar out, and he did. Hagar left with her son Ishmael into the wilderness, and prayed. God promised Hagar that her son would be the father of 12 kings of his peoples, and it was so.
Thus Ishmael became jealous of Abraham's son Isaac, to whom God's Birthright covenants would fall upon; even to this day that jealousy over God's Birthright is preached among the Islamic clerics to the Arab peoples. The Birthright is supposed to go to the 'firstborn' son. The Arabs see Ishmael as the rightful 'firstborn', simply because he was the very first son of Abraham. They do not recognize God's Promise to Abraham though, that His Covenant would be with the son of Abraham and Sarah. So ultimately, the Islamic clerics drive the Arab peoples to fight against Jews over jealousy of God's Birthright, and not just over the lesser history of the land. There are Islamic clerics living today that recognize the Jews have always had their temple standing in the holy land. Those Islamic clerics well know the history of the majority of the land originally belonged to the children of Israel after God had led them across the Jordan river into Canaan, and to wipe out the specific nations He commanded them in Deuteronomy 20:10-18.
