RE:used be Palestine, but in 1948, was annexed by the UN & became the country of Israel.
How come we have not heard a peep from the U.N. since it looks like it was the U.N. that started this problem in the first place.
Actually it was Great Britain who initiated it, but the UN approved it.
Here is the way I understand the basic history of the region. There may be a detail or two that I might not have exactly right. But that area's history is so convoluted even many scholars of the ME don't completely understand it.
Palestine had been under the control of the Brits for 40 years. Prior to that it had been under the control of the Ottoman Turks for about 400 years & prior to that, the Romans I think. The Palestinians had never ruled the land themselves, but it was their home for over a thousand years. After WWII, when Britain could no longer afford to maintain it as a colony, Lord Balfour drafted a proposal to partition the territory & turn half of it over to the Zionists to form a Jewish state & keep half of it for the Palestinians.
During the late 60's - early 70's, the Arabs launched a couple of attacks (the Six Day War & the Yom Kippur War) upon what had by then been Israel for about 20 years, but with the help of US military equipment & training, Israel was able to not only repel the attacks, but push into & capture some of the land that had been part of Palestine, thus making Palestine territory much smaller than it originally had been.
Along with several other non-war related encroachments over the years, the Palestinians' land has continued to shrink more & more.
Here is a series of maps that show the progression:
I don't have a side in their fight, but I think it's pretty obvious why the Arabs are so pissed off at the Israelis.
