Israel is facing a number of operational challenges threats and dangers, Maj.-Gen. Ido Nehushtan said Tuesday as he took up his new post as the 16th commander of the Israeli Air Force. Nehushtan took up his new post during a ceremony at the IAF's Ramat David Base in the North and during which he replaced Maj.-Gen. Elazar Shkedy, head of the air force for the past four years. "A dry analysis of the current reality shows a dynamic strategic environment that is filled with threats and dangers," Nehushtan said. "The regime in Iran combines poisonous rhetoric with real actionsâ€¦while rejecting Israel's right to exist." A pilot with thousands of hours on his flight log, Nehushtan, who previously served as head of the IDF Planning Division, holds degrees from the Hebrew University of Jerusalem, Northwestern University and Harvard University's Advanced Management Program.
