I find myself stonehearted when listening to Arab appeals for integrity of the Hijaz ("holy lands"), in the face of the historical fact of a) their having stolen most of them from the Roman Empire in the first place, and b) their having been liberated from the Turks by force of European, Christian arms in the second place.
If the British issued the Balfour Declaration concerning the settlement of Jews in Palestine, they were entirely within the rights of a conqueror to have done so. The same rights the Arabs themselves once claimed.
