Ze’ev Jabotinsky viewed the Balfour Declaration as a commitment to establish the Jewish State in Mandatory Palestine. He believed that public and diplomatic pressure on decision-makers and opinion leaders in Britain could cause that commitment to be fulfilled, either as an independent state or as a dominion within the framework of the British Commonwealth. Personally, he favored the latter. Even as the conflict of interests between Zionism and Britain became increasingly apparent, Jabotinsky maintained his faith in the Zionist connection with Britain—at least up until the publication of McDonald’s White Paper on 17 May 1939. As he saw it, the obstacle to fulfil the British obligation was the political game that the Mandatory Administration in Palestine played. He put the blame on the local administration, rather than on His Majesty’s government in London. This article presents the interpretation of the Balfour Declaration—and, by extension, the British Mandate—through the eyes of the leader of Revisionist Zionism.
