What makes the BBC so neutral. That's like saying the American press is nuetral, we both know that isn't the case. An undercurrent of Antisemitism has run through the British government since just after the Balfour agreement. The British Mandate Authority in Palestine restricted Jewish immigration, forcing many Jews to return to Europe after the second world world, while doing absolutely NOTHING to stem the flow of Arab immigrants. The British government stood squarely in the road of the establishment of a Jewish State, which is why the "Two State" solution was offered by the United Nations.
Again, your BBC report gives absolutely NO figures for what the Arab population of Palestine was in 1900, it only says that in 1922 the entire population of the area was about 3/4 of a million, and that about 500,000 of those were Arab.
Arafat isn't even "palestinian" he was born in Egypt. Like many other Arabs he immigrated into the area. Some before the 1948 Arab Israeli war, some after. When the Arab nations that dispossessed the 600,000 jews in Arab nations during 1948 reimburse the Jews for their lost property, maybe we can start talking.
The British government, though, was anything but "neutral".
