It is interesting and even surprising that the two main strategies regarding warfare were developed by European contemporaries of the late 18th and 19th centuries. Antoine Henri de Jomini (1779-1869) approached his philosophy of war in a structured and scientific way. Carl von Clausewitz (1780-1831) took a more fluid and open approach to his philosophy of war. The fact that they lived at the same time in Europe is also fascinating as they probably knew each other's writings and were potentially influenced by and were influenced by each other's philosophy. Jomini's scientific approach is more applicable to the tactical and operational levels of war, while Clausewitz approaches war more as an art or as an interaction between people which is more appropriate to the strategic and political levels of war. Although their two warfare strategies are presented as opposing strategies, comparing each of the theorists' concepts with the other theorist's work shows that they are in fact more complementary than competing as they address different levels of warfare. The concepts to be evaluated are Clausewitz's "Trinity of War", "war as a continuation of politics" and the "unpredictability of war", as well as Jomini's definition of strategy and his "Fundamental Principle of War". The first concept is Clausewitz's Trinity of War which includes “…three categories of forces: irrational forces…; non-rational forces…; and reason or rational calculation…” [Bassford, page 205]. Irrational forces are hostility and violence that originate primarily from the people and are the impetus for a political solution that may result in war. Non-rational forces refer to chance and probability which are mainly... half of the paper... repeating themselves in Afghanistan." [Sobchak, pg 239]The War Strategies of Carl von Clausewitz and Antoine Henri de Jomini do not are mutually exclusive philosophies. Clausewitz's “Trinity of war,” “war as an extension of politics,” and the “unpredictability of war” relate more to the higher, strategic, and political levels of war operational and tactical levels in the lower levels of warfare with its definition of strategy and its "Fundamental Principle of Warfare". So, if you consider their work collectively rather than as competitors, the two philosophies complement each other by addressing different segments of the specter of war.
