Israel's national security doctrine collapsed on October 7, and the way in which the Swords of Iron War is being conducted is fundamentally changing its components. After the war is over, an in-depth review of the doctrine will be required. Fundamental questions will need to be discussed, such as: Is Israel giving too much weight to the Iranian threat? What is the basis of the national approach to the Palestinian issue? What is the right balance between independence and dependence on the United States? And is Israel a country that manages risk or actively shapes its environment? The main issue may be a return to the concept of preventive war and creation of a clear ranking between the core components of the doctrine – deterrence and decisive outcome – and the other components. It might be helpful to make these discussions part of binding legislation in which, for example, any new government would have to approve its National Security Strategy in the Knesset.
