David Ben-Gurion's classic security concept made these assumptions: first, that Israel would never be able to force an absolute end to the conflict on its enemies; and second, that Israel cannot maintain a large army for long, so its security requires a reserve army and sufficient warning before war breaks out. This has resulted in a restless reality of short, intense rounds of war. The October 7 disaster prompted a sense that this concept had failed, and that it is time for Israel to adopt a new concept in which the enemy is completely defeated and no longer poses a threat. To a certain extent, the Iron Swords War is an attempt to eliminate the Hamas threat from Gaza once and for all, and possibly after that, the elimination of the Hezbollah threat as well. But can Israel eliminate Hamas (and Hezbollah)? Would attempting to do so be worth the practical price of the long war it would require? Would Israel’s society, economy, and state survive the attempt? Does the failure of Israel’s security concept on October 7 mean a new concept is required, or did the concept fail to be implemented properly on that Sabbath (and even more so since then)? In other words: Should the existing security concept be replaced or strengthened?
