Carl von Clausewitz, in his influential work published in 1832, presented a foundational perspective on the nature of war. He asserted that war should not be viewed solely as a series of battles, but rather as an extension of policy, serving as a strategic tool for political objectives. His famous declaration underscores that military action is a method to realize the goals set forth in a political context, emphasizing the inseparable relationship between war and statecraft.

Niall Ferguson's book "Colossus" explores this concept further, analyzing how warfare acts as a vehicle for political ambitions. Ferguson elaborates on Clausewitz's idea, highlighting the historical implications of viewing war as a continuation of policy by other means, suggesting that understanding this notion can provide insight into past and present conflicts and the role of power in international relations.
