Jonas Merakai writes about how wars are shaped long before the shooting starts, in factories, ministries and back rooms. His work follows the intersections of military history, economic policy and technology, tracing how ideas on paper become steel, concrete and doctrine. He has spent years studying the interwar period, where treaties promised peace while rearmament quietly gathered speed. Growing up near former industrial sites that once supplied twentieth century conflicts, he became fascinated by the ordinary landscapes that still carry the imprint of those choices. His writing aims to make complex systems legible without losing sight of human responsibility. By weaving together case studies, archival material in translation and accessible narrative, he invites readers to see arms races as the product of decisions that could have gone differently. His broader project is to help readers recognise early warning signs when technology, money and security fears begin to pull societies towards confrontation.
