This subject is far too big for one submission even though the story is as brief as it is bloody. It just goes back to May 14, 1948, when the UN abcadabred Israel into a real live country.
Most young people don't realize that the State of Israel is a VERY new international event, even though the vast population of Palestine has been Arabic since around the 7th Century.
Alas, this is a subject that no matter what you say, you're going to be hated by someone. For example, the Israeli's (now that they're there) surely have every right to defend themselves against what they call terrorists; even though for the Palestinians, the Israeli's are “invading” terrorists.
It's pragmatic to keep people ignorant of history, since contemporary events generally take on a PROFOUNDLY different meaning in the context of history.
For example, one realistically wonders how the United States, England, Spain, Germany, or Italy (or ANY country) would have responded if Palestine was not the unwilling "host" of a brand new country, but America had been informed by the UN that Washington and Oregon were now the State of Israel. What would Russia of done, or China, or even any of the Arab states if they discovered that their ancient lands were "appropriated" by a paper UN decree (after the brutal occupation of Palestine by the British from 1920 to 1948)?
Speaking of which, the obscenity of British Colonialism was literally all over the planet for decades. The British Empire could have taken lessons in morality from Genghis Khan.
Of course, from the Palestinian point of view, this 100% arbitrary historical event (i.e., the magic international creation of Israel in the heart of Palestine) is the alpha and omega of violence that has happened, is happening, and almost certainly will continue to happen indefinitely.
But, when factoring in goons like Yasser Arafat, who apparently was sent by the devil to undo ANY possibility of realistic diplomacy between Israel and Palestine (in spite of some sincere efforts from the Israeli's), the whole Israeli/Palestinian "conflict" seemed hopeless.
