IDF Chief of Staff Lt.-Gen. Dan Halutz has acknowledged for the first time that there were shortcomings in the military's performance during the recent Lebanon war, media reported on Thursday. Criticism of the military's preparedness and tactics swelled as the monthlong fighting dragged on, then ended without a clearcut victory for Israel. Questions about the wisdom of 11th-hour battles and reports of food and water shortages have fueled demands for a state inquiry into the war's conduct and the resignation of Israel's wartime leaders. In a letter to Israeli fighters, Halutz wrote that "alongside the achievements, the fighting uncovered shortcomings in various areas _ logistical, operational and command. We are committed to a thorough, honest, rapid and complete investigation of all the shortcomings and successes."
