Operation Wrath of God, a secret plan by Israel and its intelligence agency, remains one of the toughest and most brutal operations in the country's history [29edba5d]. The operation was initiated in response to the killing of Israeli athletes at the 1972 Munich Olympics and lasted for over 20 years [29edba5d]. Its primary objective was to assassinate individuals suspected of being involved in the attack, specifically targeting members of the Palestinian terrorist group Black September [29edba5d]. Mossad, the Israeli intelligence agency, compiled a list of individuals and carried out targeted assassinations with the help of PLO agents and information from friendly European agencies [29edba5d]. The operation employed psychological warfare tactics, including publishing obituaries for living individuals and providing detailed personal information to lower-level Palestinian leaders as a warning [29edba5d]. Operation Wrath of God was highly effective, as Black September never carried out another operation on the same scale as the Munich massacre [29edba5d].
