Brief History of “Palestine”
Jews have been living in all parts of "Palestine" since Biblical times. After World War I, Britain was in control of Palestine. Earlier, in 1917, it issued the Balfour Declaration. It called for the establishment in Palestine as a "national home for the Jewish people," with the understanding that the civil and religious rights of the existing non-Jewish community would be respected. Jewish presence in Hebron lasted over 3,000 years, interrupted only by the Arab pogroms in 1929. What is often referred to as “Arab East Jerusalem” hosted a vibrant and just as deep-rooted Jewish community until they were exiled and the Jewish Quarter with its ancient synagogues was destroyed by the Arab armies in 1948. Similar ethnic cleansing and murder was the fate of communities in the West Bank (e.g. Gush Etzion) and Gaza.
In 1920, the League of Nations made Britain the mandatory power in Palestine, effective in 1922. The Mandate, in line with the Balfour declaration, provided for the establishment of a Jewish national home in all or any part of Palestine. The British, however, contrary to the spirit of the Balfour Declaration and the Mandate, divided the country into two parts. They granted the area east of the Jordan River to the Hashemite tribes, thus excluding it from Jewish settlement. They limited the Jewish National Home to an area within the 23% remaining west of the Jordan River. That entire area is about half the size of San Bernardino County in California. Transjordan (the name implied that it is on the East bank of Jordan river) was given independence by Britain in 1946.
Israel declared its independence in April of 1948, on the same day as Britain relinquished its Mandate, and after the Arabs had rejected a partition plan proposed by the United Nations, a plan that the Jews had accepted. In its War of Independence, against overwhelming odds, the newly-formed Israel Defense Forces were able to defeat five combined Arab armies. Transjordan, however, succeeded in pushing westward across the Jordan River and in occupying Judea and Samaria (the "West Bank"). They were the occupiers, and they stayed in that occupation until they attacked Israel in 1967 and were defeated in the Six-Day War. During its 19 years of occupation, Transjordan, now renamed "Jordan“ (to reflect the occupation results), systematically removed all Jews from the territory. Jewish holy places were profaned and destroyed.
Israel has administered Judea and Samaria (the "West Bank") since 1967. Approximately 250,000 Jews have returned to live there. Another 250,000 Jews live in the areas of “East Jerusalem” officially annexed by Israel after 1967.
A homeland for Arab Palestinians? Of course, they deserve one. They have such a country. It's Jordan. Jordan (77% of the British Mandate) is Arab Palestine. Never in history has there been an Arab state in Judea and Samaria, and there certainly was never any mention of it during the 19 years of Transjordanian occupation.
The myth of the “occupied territories”
As Adolf Hitler discovered, the Big Lie will eventually be accepted as the truth. The Big Lie, the monster whopper of our time, is that the provinces of Judea/Samaria, often called the "West Bank," are "occupied territories."
