Unified Libertarian Theory and the Russo-Japanese War

This article applies unified libertarian theory (ULT) to the Russo-Japanese War of 1904–5, a conflict often dismissed or overlooked in modern scholarship. In reexamining the war, this study argues that Japan’s initiation of hostilities met the threshold of justified coercion under ULT’s standards. Justified coercion does not mean morally correct but rather that the casus belli falls within the descriptive framework of state behavior outlined in “Unified Libertarian Theory: Genesis” (duHoffmann 2025) and will likely not incur the costs associated with unjustified coercion. During the lead-up to the war, Japan was surrounded by hostile empires, vulnerable to economic strangulation, underestimated, and facing a deteriorating security environment. Its interest in securing Korea as a defensive buffer and deterring Russian encroachment was grounded not in an ideology of expansionism but in the preservation of national autonomy. The failure of diplomacy and the demonstrated bad faith of the Russian Empire created a condition of necessity through Russia’s eastward expansion in which preemptive action became the only viable path to survival. Finally, the war’s execution was restrained, targeted, and concluded with a negotiated peace, satisfying the requirement of proportionality. Under ULT, the Russo-Japanese War emerges as a case in which offensive war functioned as a defense of liberty. When evaluating Japan’s strategy and situation holistically and as a response to structural vulnerability rather than simply as a bid for domination, the result is a picture of disciplined statecraft. In doing so, this article affirms ULT’s central claim that force, when bound by ethical clarity and strategic restraint, can serve the cause of liberty without corrupting it.
