The phrase "We won't forget. We won't forgive" expresses retribution and determination. It has been used by various groups and individuals throughout history.
Though not directly linked to the Irgun Zvai Leumi (Irgun or Etzel), the sentiment aligns with the Irgun's history. The Irgun was a militant Zionist organization. It engaged in violence against British authorities and Palestinian Arabs before Israel's establishment. Formed in 1931, the Irgun sought a Jewish state through armed struggle. It rejected the more moderate approaches of other Zionist groups like the Haganah. Noteworthy actions include the 1946 King David Hotel bombing in Jerusalem and the 1948 Deir Yassin massacre.
The Irgun was a political predecessor to Israel's right-wing Herut (or "Freedom") party, which led to today's Likud party.[15] Likud has led or been part of most Israeli governments since 1977.
