A study in 2008 concluded that a contributing factor to the Israeli Defense Force's defeat in the Israeli-Hezbollah Conflict in the Summer of 2006 was due in large part to an over reliance on EBO concepts. However, contrary to this opinion, Dag Henriksen, PhD, Royal Norwegian Air Force Academy, highlights the reality that "the absence of a clearly identified military strategy for war or of one's objectives reduces the relevance of the concept of EBO—or, indeed, of any military concept. In other words, if you do not know where you are going, the means to get there is hardly the key problem. Thus, one risks cherry-picking the variable (in this case EBO) that actually played a subordinate role in the negative outcome for the Israel Defense Forces (IDF) during this conflict. Logically, these factors render this particular conflict largely unsuitable as an empirical foundation for harshly criticizing EBO." Henriksen's study finds that the Israeli campaign in 2006 does not provide sufficient empirical evidence of flaws in EBO.
