 On 15 October 1999 (almost a year before the Sydney 2000 Games), a memorial plaque was unveiled in one of the large light towers (Tower 14) outside the Sydney Olympic Stadium.Golda Meir and the Israeli Defense Committee secretly authorized the Mossad to track down and kill those allegedly responsible for the Munich massacre.The accusation that this was motivated by a desire for vengeance was disputed by Zvi Zamir, who described the mission as "putting an end to the type of terror that was perpetrated" in Europe.
