IDF also mounted a successful bombing mission in Iraq to destroy its nuclear reactor. It was involved in the Lebanese Civil War, initiating Operation Litani and later the 1982 Lebanon War, where the IDF ousted Palestinian guerrilla organizations from Lebanon. For twenty-five years the IDF maintained a security zone inside South Lebanon with their allies the South Lebanon Army. Palestinian militancy has been the main focus of the IDF ever since, especially during the First and Second Intifadas, Operation Defensive Shield, the Gaza War, Operation Pillar of Defense, Operation Protective Edge, and Operation Guardian of the Walls, causing the IDF to change many of its values and publish the IDF Spirit. The Lebanese Shia organization Hezbollah has also been a growing threat, against which the IDF fought an asymmetric conflict between 1982 and 2000, as well as a full-scale war in 2006. Organization All branches of the IDF answer to a single General Staff. The Chief of the General Staff is the only serving officer having the rank of Lieutenant General (Rav Aluf). He reports directly to the Defense Minister and indirectly to the Prime Minister of Israel and the cabinet. Chiefs of Staff are formally appointed by the cabinet, based on the Defense Minister's recommendation, for three years, but the government can vote to extend their service to four (and on rare occasions even five) years. The current chief of staff is Herzi Halevi. He replaced Aviv Kochavi in 2023.
