The declaration was actually a 67-word statement contained within a brief letter attributed to Lord Arthur Balfour, the British foreign secretary, dated November 2, 1917, which recognised such plan.
In an agreement with America, England viewed with favour the establishment in Palestine of a national home for the Jewish people, and promised to use their best endeavours to facilitate the achievement of the project.
However, it was also clearly understood that nothing shall be done which may prejudice the civil and religious rights of existing non-Jewish communities in Palestine, or the rights and political status enjoyed by Jews in any other country.
Balfour addressed the letter to Lionel Walter Rothschild, 2nd Baron Rothschild, a British banker, zoologist and Zionist activist who, along with Zionist's Chaim Weizmann and Nahum Sokolow, helped draft the declaration.
As such, the declaration was in line with European Zionist leaders' hopes and designs for a homeland in Palestine, Rothschild and others believed would be realised through intense immigration of Jews around the world to Palestine.
Balfour was part of the liberal government of Prime Minister David Lloyd George. British liberal public opinion believed that Jews had suffered historical injustices, that the West was to blame, and that, therefore, the West had a responsibility to enable a Jewish homeland.
The whole world knew by then that at the time of the Declaration, Palestinians - the 'non-Jewish communities in Palestine' - constituted 90 per cent of the population there.
Jews numbered about 50,000. By 1947, on the eve of Israel's declaration of independence, Jews numbered 600,000. By then, Jews were developing extensive quasi governmental institutions while provoking increasing resistance from the Palestinians as the saw the Jews 'acquiring' their land.
The Palestinians staged small uprisings in 1920, 1921, 1929 and 1933, and a major one from 1936 to 1939 but were quashed by the combination of Israel-British forces.
These are the facts that United Nations, England and the US tried to deny -- that they are the roots of this problems!
