In this book, military analyst Anders Puck Nielsen examines some of the most important conflicts of our time. Drawing on research from defence academies across the globe, he offers a clear and accessible overview of the key principles of modern warfare, presented in eleven concise chapters.

Along the way, readers learn, for example, how Finland can mobilise far more soldiers than Denmark, why North Korea’s leader is often photographed alongside massive missiles, how the F-35 could become the Danish Air Force’s final manned fighter jet, and why nuclear weapons may serve as the ultimate safeguard against global war.

The Logic of War is an insightful guide aimed at a broad audience—from military professionals to curious civilians and anyone rethinking their understanding of war and peace. Through concrete examples, the book explores conflict across land, sea, air—and increasingly in space and cyberspace. It also sheds light on the dynamics behind the war in Ukraine and explains how emerging technologies, such as drones, are reshaping warfare for both soldiers and civilians.
