The Outbreak of War during Conceptual or Doctrinal Change

While conceptual and doctrinal debates are the "bread and butter" of military organizations in peacetime, what happens when war begins before the debate is settled? The chapter explores two cases – the debate over the defensive concept on the Suez Canal line prior to the Yom Kippur War and the IDF's 2006 concept of operations and operational concept for fighting Hezbollah in Lebanon prior to the Second Lebanon War. The aim of the chapter is to illuminate the fact that conceptual debates should be monitored and managed in a way that minimizes the likelihood of conceptual incoherency when war suddenly breaks out.
