Moniker, your post on the origins of current anti Semitism has some very questionable elements. The prominent one is:
Why do you prefer the claim of the Palestinians to the land, which are exactly the same as those Israel's claim is based on --
(1) that it was their land from biblical times, and
(2) that it was promised to them in the interwar years by British governments?
It was first promised to Zionists yes Zionists, and that is not a dirty word by Arthur Balfour. Zionism arose in response to growing anti-Semitism in the old empires of the modern age, in Imperial Russia and Austria Hungary in particular but also in Imperial Germany and even in America, where the Jewish experience was not exactly a bed of roses, 'land of the free' rhetoric notwithstanding, and its aim was to stop trying to blend in and just leave, or 'go away' if you will. Oh the ironies of history.
Another irony of course is that Britain was in a position in 1917 to promise the land to anyone. This is something British people sometimes tend to overlook. The disingenuousness of successive British governments in the interwar years, making promises, concealing promises, making secret assurances, taking sides willy nilly as occasion demanded, contributed immeasurably to the brewing conflict. It is really irresponsible for citizens of great world powers to shun complexity and seek the comfort of living lives untroubled by the foreign interference of their own governments, and to jump to conclusions based on the largest headlines with the shortest words.
British interest in a Jewish state arose from wartime exigencies:
Desire to appeal to Jews living in America, Germany, Austria Hungary, and Russia (esp Russian revolutionaries who were Jewish) and perhaps have a proBritish and anti Hun impact on public opinion;
Desire to establish control of an area close to the Ottoman Empire whose demise was not a foregone conclusion at the time of the Declaration;
Desire to maintain control of Suez, important for British India and the far east, and keep France out of the Levant and away from oil as much as possible.
Oil -- control of the Arab middle east (via postwar British League of Nations mandates) and access of British commercial interests to oil was a given in the British Imperial mind. Palestine had a pipeline terminal.
Coyoacan the Balfour Declaration had the effect of encouraging Jews to up sticks and move to Palestine, and why not? It was always assumed and stated explicitly by Lloyd George that the wishes of the majority would be observed when the time came to grant statehood and decide the character of the state. Such is democracy after all, and a similar principle had guided the establishment of the state of Northern Ireland a large enough population to facilitate an economy, but a Unionist majority guaranteed.
Hence the so called invasion of Palestine by 'Zionists' from 1917 on, the majority of whom after 1945 were Jewish survivors of the Holocaust who were still facing pogroms and hatred all over Europe, and later Jews leaving their homes in the middle east where they found themselves unwelcome, and the former Soviet Union.
