The commando raid in Beirut, known as Operation Spring of Youth, also occurred. This attack included future Israeli Prime Minister Ehud Barak and Yom Kippur War and Operation Entebbe hero Yonatan Netanyahu, who are both portrayed by name in the film. The methods used to track down and assassinate the Black September members were much more complicated than the methods portrayed in the film; for example, the tracking of the Black September cell members was achieved by a network of Mossad agents, not an informant as depicted in the film.
