Ra'ayon Betar — The Ideology of Betar, by Ze'ev Jabotinsky (English translation of Hebrew original; the founding doctrine Herut adopted)

2. THE JEWISH STATE
The basis of the Betarian viewpoint consists of one idea: the Jewish State. … For this purpose, every nation must possess its own "laboratory", a country wherein the nation alone is master and can freely suit the common life in accordance with its own conception of good and evil. A people's own state is such a laboratory. … However, the single way leading to this is the creation of the Jewish State.
3. THE JEWISH MAJORITY IN ERETZ YISRAEL
What then is, practically speaking, a Jewish "State"? When can it truly be said that our country has ceased to be "Palestine" and become Eretz Yisrael? Only then, when there will be more Jews that non-Jews; for the first condition of a national state is national majority. … Thus if we desire that Eretz Yisrael should become and remain a Jewish State, we must first of all create a Jewish majority. … The first step, that deed without which there can be no Zionism, or a Jewish state, or a real Jewish nation, is the creation of a Jewish majority in Eretz Yisrael on both sides of the Jordan.
5. HADNES
This is the basis upon which is founded the entire Betarian viewpoint of building a Jewish state. It means the creation of a state comprising a Jewish majority on both sides of the Jordan. The special pride of Betar, which differentiates it from all other youth movements, in Jewry, is Monism, Had Nes. Betar signifies a generation that dedicates its life to the sole idea of a Jewish State, without recognizing any other ideals. … One should remember that one may have many ideas and respect them highly, but one can only have one ideal. To this ideal all other ideas must bow, and near it there should not and cannot exist a second ideal, for two ideals are as absurd as two gods … to the command of the highest, the supreme ideal: to the Jewish State.
6. CLASS STRUGGLE
… in Palestine, higher and mightier than class interests, the common interest of rebuilding the Jewish State rules supreme. Consequently there should be no talk of class war, a system, the harmful tendency of which, is manifested when one side threatens the other by means of strikes or lockouts. In Palestine, such conflicts must always be settled in one manner only: through obligatory national arbitration.
