About England's move, Segev writes:
The Balfour declaration...finds its place among a multitude of fruitless schemes and indulgent fantasies, except, of course, that in this case, surprisingly, the British by and large kept their word. For at least two decades they allowed the Zionist movement to bring hundreds of thousands of Jewish immigrants into Palestine, and these new arrivals set up hundreds of settlements including several towns, as well as the political, economic, military and cultural infrastructure of the future state of Israel. But if Israel’s existence originated with the British, so did the Palestinians’ tragedy. The Balfour declaration was only the opening chapter of a still unfinished story.
