Noam Federman's father, David Federman (1909-1980), a Betar activist turned Lehi fighter, was arrested by the British during the British Mandate for Palestine and interned in Africa for his Jewish nationalist activism, where he shared a cell with Yitzhak Shamir, a future prime minister. Federman was raised on stories of that period, and considers his own beliefs similar to those of Avraham Stern. When he was asked if the similarity between the wartime group's activities and those of his own group was violence against Arabs, he replied, "Hitting the enemy is not a bad thing.”
