"Vom Kriege," or "On War," is a seminal work by the Prussian military theorist Carl von Clausewitz. Written in the early 19th century, it explores the nature, theory, and philosophy of war. Clausewitz emphasizes that war is not just a series of battles but a complex interplay of political, social, and military factors. The book introduces key concepts such as the "fog of war," which refers to the uncertainty in situational awareness experienced by participants in military operations. Clausewitz also discusses the relationship between war and politics, famously stating that "war is merely the continuation of politics by other means."
