Martin Kramer deserves our thanks: in “The Forgotten Truth about the Balfour Declaration,” he has illuminated the important role played by Nahum Sokolow in the diplomacy that led to the 1917 endorsement by the wartime allies and associated powers of the idea of a Jewish national home in Palestine under British protection. He has thereby enlarged our understanding, not only of how the Balfour Declaration came about but also of how it became part of international law.
