The Real U.S.-Chinese Cyber Problem

There aren't yet clear rules of engagement or escalation in cyberspace, creating risks of unintended conflicts. 

Recent waves of cyber attacks emanated from China despite their vehement denial that they possess “cyber warfare troops.” Meanwhile, the United States, sensing its own security vulnerabilities, stood up its newest military Combatant Command, USCYBERCOM, in 2009. This enabled a coordinated defensive and offensive capability in an increasingly digitized world as evident in the U.S.-led Stuxnet and Flame malware operations against Iran in 2010. As a result, both of the prominent digital players in the international community can bring forth debilitating and warlike capabilities. Washington and Beijing even agreed to a spontaneous two-day summit in June to stem the increasingly dangerous game of digital cat and mouse. Unfortunately, the norms guiding the use of cyber forces have yet to be established.

One crucial point lost amid the backdrop of the new digitized battlefield is the lack of Chinese leadership experience both military and political in utilizing key principles of the laws of armed conflict (LOAC). LOAC principles are becoming the foundation and framework for the emerging rules on cyber warfare. Some in China are slowly recognizing this shift. Given the increasingly interconnected, globalized and legally ill-defined nature of cyber technologies, one false move by either the United States or China could steer them into a cyber collision with horrendous conventional consequences.

General Escalation of Force, Proportionality and Rules of Engagement Concepts in War

Jus in bello (just conduct in war) is the set of general laws and principles that govern the way war is fought. It also incorporates the principles of escalation of force (EOF), proportionality, and the rules of engagement (ROE). This was created to promote humane standards in warfare despite the overreaching, destructive nature inherent in war. With the end of WWII, these principles now have been codified with international and customary laws into the Geneva Convention. These embody the modern concept of the law of armed conflict.

U.S. Experience with the LOAC

The U.S. Department of Defense leadership has a vast experience with these principles as they apply to the doctrine of jus in bello. They presently use various rules, approaches, and protocols to abide by the LOAC. Prior to the start of hostilities, military planners will delineate three key principles taken from the LOAC noted earlier: escalation of force (EOF), proportionality, and rules of engagement (ROE). This is to avoid confusion and miscalculation before, during and after hostilities.

The Army’s Escalation of Force Handbook defines EOF as “sequential actions that begin with nonlethal force measures (visual signals to include flags, spotlights, lasers and pyrotechnics) and may graduate to lethal measures (direct action) to include warning, disabling or deadly shots to defeat a threat and protect the force.” Meanwhile, proportionality is military action that is not excessive in relation to the concrete and direct military advantage anticipated. The Army has a uniform Standard Rules of Engagement dictating engagement of force.

Since September 11, U.S. policy makers and military strategists have been provided a tremendous opportunity to finesse those LOAC concepts based on first-hand experience gained in Iraq, Afghanistan, Libya, Guantanamo Bay, on the Korean peninsula and off the Horn of Africa. Each of these situations has spanned a wide range of possibilities in utilizing both cyber and conventional forces. U.S. commanders were required to tailor and adjust these forces to the realities on the ground. This resulted in the integral inclusion of cyber and information warfare training across all military services and senior leaderships. The significance of these experiences has pushed U.S. policy makers to shape frameworks to govern the nebulous and proliferating world of cyber warfare.

The Tallinn Manual and Emerging Cyber Norms

The law-of-armed-conflict principles already established are guiding the discussion and implementation of the emerging rules, doctrines and frameworks that may one day govern the future of cyber warfare. Realizing the need for a LOAC as it applied to the cyber domain, various states, NGOs and individuals have begun to provide their own precepts. Last year, tremendous work and energy by scholars, policymakers and digital leaders from around the world was poured into the Tallinn Manual on the International Law Applicable to Cyber Warfare. This collaborative document provides a starting point to cover the use of force in cyber warfare by state and nonstate actors. However, this document is merely a guiding post and lacks enforcement mechanisms. There is still no globally recognized norm. China has not provided transparency or information regarding their cyber intentions. Despite this, China’s previous views on conventional use of force may offer some clues on future cyber warfare strategies.
