The occupation and holding of territory, which used to be a central component of the IDF's war concept at all levels, became almost irrelevant during Israel’s many years of fighting terrorism and guerrillas in Gaza and Lebanon. But there are three reasons why it is a big mistake to discount the value of conquered territory. First, the occupation by Israel of enemy territory (while evacuating the local population for its own protection) is considered by Israel’s enemies to be a painful loss, and the possession of territory can serve as a bargaining chip in political negotiations. Second, occupation offers the IDF an asymmetric advantage, as only it can occupy territory, clear it of the enemy, and protect it from counterattack. Third, after a long period of “wars of choice” in which Israel was the strong side, we have returned to the era of “wars of no choice” in which the occupation of territory has both internal and external legitimacy. These insights should be applied to any future war in Lebanon.
