The role of the Chief of the General Staff began with the
Haganah organization, where it was named after the head of the general staff of the Haganah. With the establishment of the IDF, the Chief of Defense and the Chief of Staff, headed by
Yaakov Dori, were converted to head the IDF. The chief of the general staff is officially appointed for a three-year term, which can be extended for another year. An exception was
Rafael Eitan, whose term was extended twice, and he served a total of five years. On the other hand, there were several chiefs of staff who did not complete their full term:
Yigal Yadin resigned amid disagreements over the IDF budget,
Mordechai Maklef served for only one year at his request,
David Elazar was forced to resign following the recommendations of the
Agranat Commission investigating the
Yom Kippur War, and
Dan Halutz resigned due to criticism of the
Second Lebanon War. Also, two chiefs of staff have given up part of their tenure extension:
Amnon Lipkin-Shahak wanted to end his term in the middle of the fourth year, due to his desire to move into politics and run for prime minister.
Haim Laskov asked not to serve a fourth year due to his disagreements with
Shimon Peres. In 2005,
Ariel Sharon and
Shaul Mofaz did not extend
Moshe Ya'alon's term to a fourth year, during which he was interpreted as a dismissal in light of Ya'alon's opposition to the
disengagement plan. In order to prevent such problems in the future, and as was done for other positions such as that of the President of the State, Defense Minister
Amir Peretz appointed Major General
Gabi Ashkenazi in 2007 for a period of four years, thus removing the uncertainty regarding the addition of the fourth year. Ashkenazi raised the issue of extending his term to a fifth year. At the end of his term, the Chief of the General Staff (like other senior members of the Israeli defense establishment) has a cooling-off period of three years before he can be elected a Member of the Knesset, be appointed a Minister in the Government or be elected Prime Minister. ==Legal position==
