That's not a problem to a geneticist or an evolutionist.
roflmao Yeah the Lebanese, Egyptians, Syrians, etc. all got along like lovebirds before the Israelis arrived.
I disagree with you LG. The Palestine province of the Ottoman empire was more or less peaceful for 402 years while it was ruled by the Ottomans (1516 - 1918). The area was a Muslim majority where Jews were treated the same as other infidels (ie Christians). But as long as Ottoman citizens paid their taxes, they had religious freedom and access to the Ottoman criminal justice system... which officially did not discriminate along religious lines. Jews were always an integral part of the Ottoman empire. Many Jews have held powerful positions in the Ottoman government.
Egyptians invaded in 1832 (after 316 years of peace), but were tossed out in 1840 by a treaty land swap which gave the region back to the Ottomans. The area was peaceful again until WWI when it was invaded by the Brits in 1917 (after 85 years of peace). At the end of WW I, Palestine experienced about a year of military campaigns and battles between the Brits and the Ottomans. Palestinians fought on both sides.
Very soon after this region became controlled by the British (eventually becoming a British protectorate), tension escalated between the indigenous people and successive waves of Zionist Jews who claimed that God gave Palestine to them.
The 1920 Arab revolt (more like a riot) which killed 5 Jews and 4 Arabs injuring about 250 (mostly Jews) started as a result of a rumor that Zionist Jews intended to cleanse the holy lands of non-Jews and establish a homeland for Jews only. An angry Arab mob attacked mostly Palestinian Jews who had little to nothing to do with the Zionist movement. This was probably the first skirmish in what would eventually become an ethnic cleansing war.
After the 1920 revolt, Palestine became tense with simmering hostility between the indigenous people and the Zionist immigrants. But Palestine remained more or less peaceful for 9 years.
In 1929, a riot exploded in Palestine which resulted in about 250 deaths and over 400 injured (about even number of Jewish and Arab casualties). The 1929 riot ignited when Arabs protested Jewish attempts to turn the West Wall of the Al Aqsa into a Jewish only religious area in what they believed was a first step to turn the Al Aqsa Mosque into a Jewish Synagogue. (In 1967 after the Zionists conquered Jerusalem, one of their first acts was to demolish the Arab neighborhood next to the wall along with a historically significant Mosque and a Muslim school) I believe Israel has since made this area off limits to Arabs and its now a place of Jewish worship.
The 1936-1939 revolt was a direct result of Palestinian push for independence and an attempt to end to mass Zionist immigration, which Palestinian Arabs feared would result in the creation of a Jewish only state where they would become second class citizens subservient to the Zionists. British and Zionist military forces killed about 5000 Arabs, while injuring about 15,000. Jews and Brits suffered about 500 deaths. Today this region is a Jewish State, where Arabs are second class citizens subservient to the Zionists.
In 1947, Zionists started an ethnic cleansing war during which some of the more extreme Zionists terrorist organizations (The Stern Gang and Hagana) carried out a string of atrocities. Even moderate Zionists were shocked by the excesses of these Zionist extremist organizations who committed acts of terror, rape and torture. They attacked dozens of Arab villages, showing no mercy and taking no prisoners. They would murder every Arab man, woman and child... even babies).
Since 1947, Arab Palestinians have been attacked repeatedly by Zionists and pushed into ever smaller enclaves. Many Palestinian villages today resemble prisons surrounded by walls, razor wire and guard towers. The people inside these prisons have no recognized rights or freedoms. They are murdered with impunity on a regular basis by Zionist extremists, police and soldiers.
Today Palestinians suffer discrimination, oppression and injustice in every part of their life. No doubt some of them are bitter. Many have resorted to violence. However on the plus side, Palestinians have a growing non-violent resistance movement. Every week Palestinians, along with international volunteers (including many Jews and Israelis) protest the inhumane conditions suffered by Palestinians.
If you like I can post links backing this summary of Palestinian history and the cause of the current conflict. I don't think the reason for the hostility is murky. While religion plays a role in this conflict, IMO, it really wouldn't matter if Muslims, Christians or aliens from outerspace immigrated to this region and tried to remove the locals. The locals would be just as hostile to anyone who did these things to them..
