The article was meant as an "extension of the classical Just War Theory", and as a "[needed] third model" or missing paradigm besides which of "classical war (army) and law enforcement (police).", resulting in a "doctrine (...) on the background of the IDF fight against acts and activities of terror performed by Palestinian individuals and organizations." In this article, Kasher and Yadlin came to the conclusion that targeted killings of terrorists were justifiable, even at the cost of hitting nearby civilians. In a 2009 interview to Haaretz, Asa Kasher later confirmed, pointing to the fact that in an area in which the IDF does not have effective security control (e.g., Gaza, vs. East-Jerusalem), soldiers' lives protection takes priority over avoiding injury to enemy civilians. Some, along with Avishai Margalit and Michael Walzer, have recused this argument, advancing that such position was "contrary to centuries of theorizing about the morality of war as well as international humanitarian law", since drawing "a sharp line between combatants and noncombatants" would be "the only morally relevant distinction that all those involved in a war can agree on." As of today "The Spirit of the IDF" (cf. supra) is still considered the only binding moral code that formally applies to the IDF troops. In 2009, Amos Yadlin (then head of Military Intelligence) suggested that the article he co-authored with Asa Kasher be ratified as a formal binding code, arguing that "the current code ['The Spirit of the IDF'] does not sufficiently address one of the army's most pressing challenges: asymmetric warfare against terrorist organizations that operate amid a civilian population". Budget During 1950–66, Israel spent an average of 9% of its GDP on defense. Defense expenditures increased dramatically after both the 1967 and 1973 wars. They reached a high of about 30% of GDP in 1975, but have since come down significantly, following the signing
