Betar's Ideology is made up of 3 Sections;
Betar, Hadar & Tagar

Betar -
The love of the entire land of Israel. Betar supports the concept of a Jewish state with a Jewish Majority in its biblical-homeland. The entire land of Israel as given to the Jewish people by G-d with it's eternal capital Jerusalem. We therefore wholeheartedly support the settlement of all of Israel including Judea, Samaria, Gaza and the Golan Heights, and support the rights of all Jews to live anywhere in Israel.

Hadar -
The nearest translation of the word Hadar is nobleness. Jabotinsky always pointed out that every Jew, no matter who he is, is a descendant of King David and Solomon, and should therefore act in a Nobel manner.

Tagar-
Tagar is the Betar principle of Activism as it says in the Betar Anthem 'Silence is despicable'. Therefore Betar has various campaigns and does whatever is possible to act for various Jewish causes depending on the time and place.
