During his tenure at the Mossad, he helped carry out Operation Wrath of God, the Israeli response to the Munich Massacre, and dealt with the lead up and aftermath of the Yom Kippur War in 1973. After the German government refused to accept an Israeli team during the Munich hostage crisis, Zamir was sent to observe any activities. He was at the Fürstenfeldbruck airbase the night that the failed rescue attempt left all nine remaining Israeli hostages dead. Zamir was interviewed about the incident in 1999 when he spoke with the producer of One Day in September, a documentary on the massacre. In it he strongly criticized the German rescue effort for its complete lack of coordination. He had previously been interviewed on this subject for an NBC profile during their coverage of the 1992 Barcelona Olympics, and he has discussed the massacre several times since. Zamir currently resides in Zahala, a neighborhood in the north of Tel Aviv.
