Recent years have seen growing concern over the use of cyber attacks in wartime, but little evidence that these new tools of coercion can change battlefield events. We present the first quantitative analysis of the relationship between cyber activities and physical violence during war. Using new event data from the armed conflict in Ukraine—and additional data from Syria’s civil war—we analyze the dynamics of cyber attacks and find that such activities have had little or no impact on fighting.

"...[A]ctors that employ gray tactics in cyber operations need not be successful in actually infiltrating a system to further their revisionist ambitions. Rather, the sheer ramifications from the cyber action itself, has the power to disturb a nation's psyche and challenge the geopolitical status quo."

The defining question about global order for this generation is whether China and the United States can escape Thucydides’s Trap. The Greek historian’s metaphor reminds us of the attendant dangers when a rising power rivals a ruling power—as Athens challenged Sparta in ancient Greece, or as Germany did Britain a century ago. Most such contests have ended badly, often for both nations, a team of mine at the Harvard Belfer Center for Science and International Affairs has concluded after analyzing the historical record. In 12 of 16 cases over the past 500 years, the result was war. When the parties avoided war, it required huge, painful adjustments in attitudes and actions on the part not just of the challenger but also the challenged.
