The Balfour Declaration of Nov. 2, 1917 was a letter from British Foreign Secretary Arthur Balfour to Baron Rothschild stating that “His Majesty’s government views with favour the establishment in Palestine of a national home for the Jewish people.” In 1922, the League of Nations adopted this and made the British Mandate “responsible for putting into effect the declaration,” which led to the UN vote in 1947 and the establishment of the State of Israel.

British Prime Minister Theresa May’s exact quote before the British House of Commons on Oct. 25, 2017, was: “We are proud of the role that we played in the creation of the State of Israel, and we will certainly mark the centenary with pride.”
