This is from the UN website I have just posted interesting and a good counter argument to the website posted by Janh:
"The question of Palestine was brought before the United Nations shortly after the end of the Second World War.
The origins of the Palestine problem as an international issue, however, lie in events occurring towards the end of the First World War. These events led to a League of Nations decision to place Palestine under the administration of Great Britain as the Mandatory Power under the Mandates System adopted by the League. In principle, the Mandate was meant to be in the nature of a transitory phase until Palestine attained the status of a fully independent nation, a status provisionally recognized in the League's Covenant, but in fact the Mandate's historical evolution did not result in the emergence of Palestine as an independent nation.
The decision on the Mandate did not take into account the wishes of the people of Palestine, despite the Covenant's requirements that "the wishes of these communities must be a principal consideration in the selection of the Mandatory". This assumed special significance because, almost five years before receiving the mandate from the League of Nations, the British Government had given commitments to the Zionist Organization regarding the establishment of a Jewish national home in Palestine, for which Zionist leaders had pressed a claim of "historical connection" since their ancestors had lived in Palestine two thousand years earlier before dispersing in the "Diaspora".
During the period of the Mandate, the Zionist Organization worked to secure the establishment of a Jewish national home in Palestine. The indigenous people of Palestine, whose forefathers had inhabited the land for virtually the two preceding millennia felt this design to be a violation of their natural and inalienable rights. They also viewed it as an infringement of assurances of independence given by the Allied Powers to Arab leaders in return for their support during the war. The result was mounting resistance to the Mandate by Palestinian Arabs, followed by resort to violence by the Jewish community as the Second World War drew to a close."
Unfortunately the hand of colonial Britain was involved in this tragedy too !!
