In 2008, in a background paper on Israel’s operations in Gaza, Israel’s Ministry of Foreign Affairs stated:
In practice, two key questions arise in relation to the legitimacy of the planning … of an operation: 1) Is the target itself a legitimate military objective? and 2) Even if the target is in itself legitimate, is there likely to be disproportionate injury and damage to the civilian population and civilian property.

In July 2010, in a second update of its July 2009 report on Israeli operations in Gaza between 27 December 2008 and 18 January 2009, Israel’s Ministry of Foreign Affairs stated:
150. The IDF [Israel Defense Forces] has adopted important new written procedures and doctrine designed to enhance the protection of civilians in urban warfare, including by further emphasizing that the protection of civilians is an integral part of a commander’s mission. In addition, the procedures require increased attention to civilian matters in operational planning. Although protection of civilians during military operations has long been part of IDF training and doctrine, the new procedures mandate additional comprehensive protection. These revised procedures stem from general understandings and lessons learned both in Gaza and other military operations conducted by Israel in recent years.
151. The new procedures and doctrine also specify steps to better insulate the civilian population from combat operations and to limit unnecessary damage to civilian property and infrastructure, and require integration of civilian interests into the planning of combat operations. This involves advance research into and the precise identification and marking of existing infrastructure, including that pertaining to water, food and power supplies, sewage, health services, educational institutions, religious sites, economic sites, factories, stores, communications and media, and other sensitive sites as well as cultural institutions.
152. Furthermore, the new written procedures mandate the planning for a number of additional provisions aimed at safeguarding the civilian population. This includes: safe havens for civilians to take refuge; evacuation routes for civilians to safely escape combat areas; medical treatment for civilians; methods for effectively communicating with and instructing the population; and provisions for humanitarian access during curfews, closures and limitations on movement. Finally, the new written procedures require the assignment of a Humanitarian Affairs Officer integrated in each combat unit beginning at the battalion level and up, with responsibilities for advising the commanding officer and educating the soldiers with regard to: the protection of civilians; civilian property and infrastructure; the planning of humanitarian assistance; the coordination of humanitarian movement; and the documentation of humanitarian safeguards employed by the IDF.
153. While the majority of these issues were already addressed in various operational orders and guidelines in existence prior to the Gaza Operation, the new revised procedures are important because they are comprehensive and applicable to all stages of military operations, including the crucial stage of planning.
