Indeed, information is—to adapt Thucydides’ wisdom—the modern money that fuels war. Those who have the fastest Observe-Orient-Decide-Act (OODA) data loop will be able to dominate the cyber battlespace. Better information means more comprehensive threat intelligence, faster response times, and more robust offensive capabilities. Thucydides is a relevant lens through which to understand modern data and information warfare, but he is just one such example. Cyber raises many new questions that strategists never could have exactly foreseen. That does not mean, however, that old theories are irrelevant. From Sun Tzu’s Art of War to Thomas Schelling’s Strategy of Conflict, we should look to the breadth of complex, thought-out strategies that others have laid before us to answer the complex questions of our digital age.
