Code War: How Nations Hack, Spy, and Shape the Digital Battlefield

Allie Mellen’s Code War analyzes how major powers employ cyber operations alongside traditional military tools to pursue geopolitical objectives.

Drawing on historical examples and recent cyber campaigns, she explains differences in doctrine, organization, and strategy among the United States, China, and Russia.

The book covers espionage, wipers, coordinated attacks, and information operations, showing how cyber fits into multi-domain warfare.

Mellen emphasizes the importance of coordination, attribution challenges, and the choices nations make about escalation and proportionality.

The work aims to make cyber geopolitics accessible to non-technical readers while offering insights valuable to security professionals.
