Following the
capture of Adolf Eichmann,
Isser Harel became preoccupied by the Holocaust, which hardened his attitude towards the German scientists. He said when challenged about the operation, "There are people who are marked to die". The campaign ended when Israeli Prime Minister David Ben-Gurion demanded that Mossad halt the attacks. Then-Foreign Minister
Golda Meir and Israeli diplomats trying to build relations between West Germany and Israel were furious about the attacks. Harel was compelled to resign and
Meir Amit, his successor as chief of Mossad, claimed that Harel had overestimated the danger to Israel posed by Egypt's weapon programs.
Yitzhak Shamir and others resigned from the Mossad in protest at Harel's treatment.
David Ben-Gurion quit his post three months later. The combination of the death threats and diplomatic pressure drove the scientists away from Egypt by the end of 1963. By 1967, Egypt's rocket program had come to a standstill and Egypt turned to the Soviet Union, which supplied it with
Scud B rockets. ==References==
