In This Cyber Era, Machines Wage War but Human’s Still Pull the Trigger

IMPORTANT READS

FEAR, HONOR AND INTEREST-Over the past quarter century, the information technology revolution has transformed relations between people and between states, including in the conduct of warfare. For the U.S. military, the manifestations of this revolution have covered the full spectrum from the dramatic to the prosaic. Unmanned aerial vehicles, ships, and ground systems now carry increasingly sophisticated surveillance capabilities and precision guided weapons. (General Petraeus with President Obama-photo above.) 

Less visible, but also hugely important, has been development of the ability to integrate and analyze vast quantities of intelligence from all sources and determine precise locations of friendly and enemy elements. Finally, we cannot overlook growth of the seemingly matter-of-fact but nonetheless essential reliance on email, video teleconferences, and applications like PowerPoint to communicate, share information, plan, and perform the tasks of command and control. 

Information technologies that did not exist at the time of the first Gulf War are now so fundamental to the conduct of military operations that it is difficult to imagine functioning without them. And the growth of the internet, social media, and now the “Internet of Things” represents a further stage in the information technology revolution whose full consequences are still unfolding. Nonetheless, some preliminary implications of such cyber capabilities for warfare are already clear. 

First, cyberspace is itself now an entire new battlefield domain, adding to the existing domains of land, sea, air, subsea, and space. This reality has enormous ramifications for military doctrine, operations, organizational structures, training, materiel, leadership development, personnel requirements, and military facilities. Most significantly, it adds a powerful new element to the challenges of the simultaneous “multi-domain warfare” in which we are now already engaged and for which we need to do more to prepare in the future. 

Second, cyber technology is adding another element to the already ongoing dispersion and fragmentation of global power. While no nation has contributed more to the growth of the internet and the digitized world than the United States (and no nation has developed more sophisticated cyber military capabilities), the nature of these technologies ultimately presents one more disruptive challenge to the preeminence that the U.S. has enjoyed since the end of the Cold War, as others exploit the potential of offensive cyber capabilities in new and increasingly sophisticated and diabolical ways. 

Examples of this include the use of cyberspace by extremist networks like ISIS and Al-Qaeda to inspire far-flung terrorist strikes; by Russia to wage ideological and political warfare that seeks to undermine the cohesion and self-confidence of the Western democracies; and by China to collect the technological know-how that is speeding its already rapid rise and undercutting America’s conventional military edge and industrial advantages. 

Security in the century ahead will depend more on our moral imagination -- and with it, the ability to develop concepts of restraint -- than it will on amazing technological breakthroughs. 

Third, cyber capabilities are further blurring the boundaries between wartime and peacetime, and between civilian and military spaces. These are distinctions that have, for various reasons, been eroding in recent decades and which technological developments are now accelerating. At present, it is likewise clear that offensive capabilities are outstripping defensive and retaliatory options. And as long as difficulties in identifying and attributing responsibility for cyberattacks persist, that reality is likely to undercut deterrence and encourage aggression in cyberspace. 

Yet even as technological changes inspire us to speculate on the future of warfare, perhaps the most important insights about the implications of the cyber age can be gleaned from the past.

While technology promises to disrupt the conduct of war, it is equally important to recognize what it will not alter -- namely, the causes of war, which continue to lie in the character of humanity. As Thucydides documented more than two millennia ago, it is the elemental forces of fear, honor, and interest that are the wellsprings of conflict, and it is often the choices of individual leaders that determine how conflicts develop. 

It was for this reason, in fact, that, when I was in uniform, I argued against the concept of “network-centric warfare” -- put forward in the late 1990s -- and instead contended that a better formulation would be “network-enabled, leadership-centric warfare.” It is, after all, still leaders who determine strategies and make the key decisions. And even as development of autonomous weapons systems and other such capabilities proceeds, parameters for actions by such systems will continue to be established by human beings. 

Furthermore, history suggests that humanity’s capacity for technical innovation often outpaces our strategic thinking and development of ethical norms. Indeed, the methodical development of doctrine around nuclear weapons by the “Wizards of Armageddon” in the 1950s and 1960s, which did much to help prevent a nuclear apocalypse, appears to have been the exception rather than the norm. More typical is the experience of the European powers of the early 20th century, which failed to recognize that the mass industrialized armies they were constructing were the components of a doomsday machine that would unleash a civilizational slaughter that none of the combatants had previously considered possible. 

As we and other major powers race to develop cutting-edge cyber capabilities -- expanding swiftly into realms such as robotics, bioengineering, and artificial intelligence -- we would be wise to devote equal energy and attention to considering the full implications of our ingenuity. Security in the century ahead will depend more on our moral imagination -- and with it, the ability to develop concepts of restraint -- than it will on amazing technological breakthroughs. 

This in turn suggests a final reality about warfare in the age of cyber. Regardless of the innovations that lie ahead, technology by itself will neither doom nor rescue the world. Responsibility for our fate, for better or worse, will remain stubbornly human.
