46 Summary 1. Developments within the region have led the IDF to deal with a wide range of threats that challenge its operating concept and force buildup processes ensuing from this concept. The change is embodied primarily in the development of sub-state enemies, such as Hezbollah and Hamas, and threats from countries with no common borders with Israel. 2. This document provides the fundamental concept for the use of force in shared contexts for all operational arenas against sub-state enemies and in the IDF's various functional situations: Routine, Emergency, and War. 3. From these use of force principles, this document derives force buildup guidelines, to be used by the force buildup planners to reinforce the power of the IDF within the coming years. 4. This document requires follow-up actions, mainly the development of specific operational concepts within the war arena, and the development of operational concepts for the principal commands. At the same time, the force buildup commands must formulate the specific force buildup concepts derived from this document. 5. The IDF has always based its power on the quality of its personnel and the deep understanding that the IDF guarantees Israel's national existence. Therefore, the IDF will act to provide security under any conditions, while utilizing the basic characteristics of its commanders and soldiers, which are: fighting spirit, initiative, quality of action, and the ability to carry out complete missions in an uncompromising manner.
