Thucydides's Trap, String Theory, Modelski's Table

An Analysis of Great Power Competition in the Modern Age

Editor's Note. Theories I is Arctic Ledger's first publication devoted to the ideas underlying geopolitical analysis rather than to a specific supply chain, vulnerability, or region. Unlike the case-driven essays of Volume I, these three pieces (on weaponized interdependence and leverage, on the interaction of economic coercion and the probability of war, and on the gaps opening up in Modelski's long-cycle model) are offered as theory: frameworks meant for testing, argument, and revision rather than as calls to action. They are not published elsewhere at this time. — Jack M. Lindstrom, Founder & Publisher, Arctic Ledger

Long Cycles and Critical Minerals: An Analysis of Modelski's Table in the 21st Century

Modelski's long-cycle table has an unfinished row for the 2000s. This essay argues the blank is not a data gap but evidence of three broken assumptions (the embedded challenger, the fractured K-wave, and legitimacy as a variable rather than a constant) and proposes a revised chokepoint cycle model.
