How the Terrorist Attacks of 2001 Have Signalled a Fundamental Change in the Nature of Conflict (ARI)

Sebastian L. v. Gorka. ARI 135/2010 - 14/9/2010

Theme: There are still fundamental questions to be answered on the nature of conflict post-9/11 and our existing understanding of war must be reassessed.

Summary: In this ninth year of the epoch-defining conflict which for most Americans began on 11 September 2001, fundamental strategic questions remain unanswered. What is the nature of the enemy? Is it an organisation, network, movement or ideology? What are the long-term objectives of this enemy? Does it have a Clausewitzian centre of gravity? Should we even use the term enemy, or should the vast resources that Washington dedicates to national security be spent instead on ameliorating the ‘upstream factors’ underlying violent extremism (to quote a phrase used by a close advisor to President Barack Obama)?[1] This paper attempts to answer some of these questions and explain why our existing understanding of war’s nature must be reassessed.

Analysis: If we turn to Sun Tzu to answer such fundamental questions, we must start with ourselves. We must understand who we are and what we represent before we can hope to identify what threatens us and our value system. The gross if superficial outline is clear. America is today the world’s sole superpower. Yet despite its immense power advantage over other states, nine years ago it suffered the deadliest nonconventional or irregular attack in modern history. As a result, it is now involved in two non-traditional conflicts, one in the Middle East and one in Central Asia (neither area having dominated the work of military planners during the decades of the Cold War). At the same time, America is focusing much of its remaining national security capacity on neutralising the threat of terrorist attacks against its homeland.

But who we are and, therefore, where we need to go are not such simple questions to answer. Just as the Human Terrain Teams deployed in Iraq and Afghanistan are meant to set the stage for military operations and explain the human context in which our forces are to function, we must understand our own context –our own human terrain– beyond the most recent crisis and at a level of analysis that is deeper than that supplied by the mass media or talking heads.

Some would call this an exercise in having an appreciation for the strategic culture of the US. That may be a useful approach, but given the events of the last 70 years, it would be more accurate to talk of having an appreciation of the evolution of US strategic culture rather than depicting it as a static reality fixed in the post-9/11 environment.

As a result, in order to appreciate fully the difficulties we face in today’s irregular context and to have a hope of overcoming them, we must see the larger picture and the trend lines that have shaped it, for how we think strategically is an aspect of who we are. After all, strategic culture influences how we approach threats, and it challenges and shapes our responses. World War II and the Cold War left us emphasising firepower, technology and nuclear deterrence. Then came the strategic reality of the 1990s, which lacked any similarity to the preceding 40-plus years and thus had a distinctly negative impact on our ability to think about what national security really meant in a post-Cold War world. Now we must honestly assess how the intelligence gathering and forecasting habits of World War II and the Cold War have created systemic obstacles to providing basic informational support to the types of missions we are now expected to execute.[2] While we have invented new capabilities, such as offensive unmanned aircraft system platforms and stealth technology, and while we have written new doctrine for current missions (for example, Field Manual 3-24, the latest counterinsurgency manual), neither of these facts proves that we have fundamentally reworked the entrenched culture and architecture of a US national security establishment predicated on neutralising nation-state threats.

The Global Context
In addition to delving into the premises underpinning our strategic culture, we must ask similar fundamental questions about the context in which the rest of the world finds itself at the beginning of the third millennium. Without getting into the lucrative but unscientific black art of long-range projection, we must ask questions related to relative power, the role of ideology and the influence of demographics on actors who in the past were not of concern to us, or who simply did not exist in an age of bipolar conventional standoff. Nation-state actors and non-nation-state actors alike are affected by new drivers of change.[3] Power can no longer be measured simply in terms of gross domestic product or tank regiments. As Ralph Peters eloquently pointed out over a decade ago, survival may have far more to do with a given community’s desire and capacity to absorb and manipulate large amounts of information than with the classic metrics of power.[4] Similarly, the vulnerability of a given state may be measured more in terms of its access to clean drinking water or the size of its male population under the age of 20 than by its proximity to malevolent neighbours.

The Conceptual Context
Lastly, and perhaps most difficult of all, it is the duty of all senior officials involved in providing national security to seriously and most candidly reassess core assumptions upon which our existing systems of analysis and planning are based. We must evaluate how apt these central concepts still are and formulate new principles should they be found wanting. Beyond the foundational core values of the Nation, such as those enshrined in the Declaration of Independence and the Constitution, we must recognise that no concepts are immune to critique and reappraisal when it comes to securing the homeland. America’s founding values are sacrosanct and immutable, yet we must be ever imaginative and flexible in how we realise and protect them. For example, should the ‘Wondrous Trinity’ of Clausewitz be found wanting in an age of globally dispersed non-state actors and cyberwarriors, it must be discarded –or at least significantly reworked– if it is to have utility in an age of proliferating non-state actors, the likes of which the Prussian theorist could never have imagined.

The Context of Classical War Theory
With regard to this last point, we would be well served by engaging in an even more sweeping survey of our current context to include century-long trends. The blogosphere, professional military education journals and civilian publications provide ample reading on the core issues of how irregular war differs from conventional warfare. Nevertheless, we should take our quest seriously and in a way that steps beyond the theoretical navel-gazing of purely semantic debates. When Clausewitz gave us his immortal dictum on war as the continuation of politics, he was writing in a specific historical and socioeconomic context. No matter how useful his analysis may seem, it cannot be divorced from the age in which it was born, an age when conventional war dominated strategic thought.

Clausewitz’s On War must be understood as one man’s forceful attempt to impose meaning on the clash of national arms. More specifically, it must be appreciated as an act of intellectual pilgrimage by an officer seeking to explain the destruction of his military culture by an upstart foe successfully using the radical approach of levée en masse to decimate its professional enemy. That is why in his Wondrous Trinity, Clausewitz makes rational government ends the drivers behind the actions of his skilful commander, who harnesses the passion and hatred of his troops (the population).

Clearly, the (Westphalian) nation-state construct informs everything Clausewitz wishes to achieve. We are therefore fully justified in reassessing his model in an age that sees violence applied most often in non-Westphalian ways –by non-state actors–. Similarly, context also applies to the other great strategist, Sun Tzu, who is also a victim of his age. Why else the emphasis on victory without combat being the ultimate goal? Unless we see Sun Tzu as a product of the Warring States Period before China was united, we cannot understand that his writings were driven not by the desire to destroy the enemy but to co-opt the political entities that would become the building blocks of a new empire.

Sun Tzu’s context was the drive for unity in the China of the Warring States. Clausewitz’s was the Napoleonic revolution in warfare and a young Westphalian system. As such, On War was crucial to understanding the Westphalian period. However, although much can be said of the post-9/11 age, Westphalian is not what springs to mind. As Martin van Creveld noted in a recent speech at the National Defense University, ‘What [Clausewitz] never imagined was a world in which many, perhaps even most, belligerents consist of nonsovereign, nonterritorial organizations’.[5]

Hence, we can ask some obvious but new questions and ascertain whether the old models apply. When discussing actors who engage in irregular warfare against us, how Clausewitzian is the enemy’s understanding of the purpose of war? For example, is al-Qaeda, or even Iran, driven by the same functional approaches to the use of violence as we are?[6] On War may remain the key text about nation-on-nation conflict between actors operating on logical cost benefit lines directly connected to obvious political gains. But how is such a calculation factored into an understanding of the utility of violence when we are facing a religiously motivated foreign-fighter brigade in Iraq, a unit of the Quetta Shura in Afghanistan or a suicide bomber on a commercial flight crossing the Atlantic?

Clausewitz was right about the immutable nature of war,[7] but his Westphalian context drove his understanding of the role of raison d’état and the trinity of forces that the state both embodied and leveraged. Those forces still exist, but the new actors we face – whether they be the Taliban in Afghanistan or al-Qaeda in Yemen– have mixed these ingredients in new ratios and combinations, wherein rational, policy-oriented cost-benefit analysis and justifications have been trumped or qualified by less dispassionate and more otherworldly influences.

The triangle of Government, People and Army (or Commander), which respectively represent reason (or policy), passion and skill, is less than useful for many of the irregular threat groups we are fighting today because they are not nation-states. Take, for example, al-Qaeda. Since the loss of its Afghan base of operations, there is no specific government or nation that is associated primarily with this foe. The violence of al-Qaeda is not instrumental to an end-state akin to the policy goals of a ‘normal’ government. Its ends are driven by the religiously fuelled visions of ideologues, some alive today, but many, such as Sayyed Q’utb and Abdullah Azzam, deceased. None of these ideologues or irregular elites politically represented a nation in the Westphalian sense, making the triangle/trinity out of date.[8]

Simultaneously, the role of the military commander is not filled by a professional warrior subordinated to a political elite in the case of the irregular enemy. Osama bin Laden is a self-taught warrior, a mujahideen who never spent time at a war college or wore the uniform of a national army. Furthermore, his skill is not measured solely in the way that concerned Clausewitz, prowess on the battlefield. Rather, he must be understood in non-military terms as an ideologue in his own right, an information warrior who inspires by personal example. The commander of the Clausewitzian Trinity was judged by his ability to prevail despite the friction and fog of war. Bin Laden is measured less by his success on the battlefield –which has been minimal since 9/11– than by his authenticity as a ‘true believer’. He is an example of a holy warrior, prepared to die not for a political end-state but for a transcendental truth, judged by his capacity to inspire other violent non-state actors.[9]

Finally, the passion- and hatred-driven third part of Clausewitz’s Trinity must be redefined. No longer is the enemy limited by the resource his national population represents. Bin Laden, like the Muslim Brotherhood, is not constrained by whether he can rally the citizens of one particular nation behind the cause of war or by their willingness to be drafted into a national army. Potential irregular warriors can be recruited from Algeria, Somalia or Michigan, for al-Qaeda’s definition of population is not territorially bound but religiously defined by the idea of the ummah, or global Islamic community. And in this he is not alone. The anticapitalist extremists who so often violently trouble the representatives of the old Westphalian order, such as the Group of Eight, are also unrestricted in their mobilisation by national borders.

Consequently, although reports of the death of the nation-state may have been greatly exaggerated, a definition of war that pertains only to nations is indeed dead. Clausewitz’s Trinity still applies to state-on-state conventional war (‘ideal war’), but it must be supplemented with another trinity that can depict the types of actors our troops are already fighting (see Figure 1).

A Wondrous Trinity for Today
Clausewitz’s Trinity divided the world into three parts: the government, the governed and the defenders of the state. Each reflected a different characteristic: rationale, passion or skill. Although the triangular representation of the three implies equality, just as with the Christian Trinity, there is favouritism. As the Son sits on the right hand of the Father, and the Spirit serves them both, it is clear from On War that the party Clausewitz privileges is the military, or more specifically, the artful commander who harnesses the population’s passion and might so the nation may realise its goals.

Today’s irregular enemy should be understood in a more egalitarian fashion. Just as the information and media worlds have been democratised, with Web sites and blogs turning consumers into producers and vice versa,[10] the trinity of the irregular enemy affords and invites an interchangeability of roles and functions. Leaders can be fighters, followers can become leaders and both can interpret and feed into the enemy’s understanding of why force is necessary and what ultimate purpose it serves. In other words, the components of the Clausewitzian Trinity have become utterly fluid and interchangeable.

As we have noted, this has profound implications for the resources the enemy can mobilise and with which he fights us. In Westphalian war, the enemy only has the people of his nation-state. For today’s enemies, the limitations of borders and citizenship have vanished. We are faced by a Saudi master-terrorist as the leader of al-Qaeda, but violence carried out in the name of the ‘truth’ that he serves can be executed by Nigerian students on commercial airliners or US Army majors of Palestinian descent. There are no limits as to who can be recruited and deployed against us. The only requirement is that they subscribe to the religious ideology that is global jihad.[11]

A second deep ramification is that in the wars America fights today, national interest no longer defines the enemy’s use of force. Rather, it is truth as defined not by the elite of a government, but by ancient religious texts or their interpretations by politically and transcendentally motivated ideologues. Clausewitzian raison d'état, the objective of violence, is no longer bound by cold or technical definitions of national interest. If ultimate approval can be gained by being a suicide bomber or killing non-combatants in the name of religious glory, then the rationale for violence must not be interpreted by US national security elites as being subject to the limitations of a Westphalian framework of analysis. As a result, in today’s irregular context, we can replace the rationale of the trinity with the transcendental end that the true believers see themselves as serving.

Finally, in the new threat environment, the third actor of the Clausewitzian Trinity –the commander and his forces– is radically redefined. During the early 20th century, and then the Cold War, irregular warfare’s practitioners could be easily understood as all having one very Westphalian goal for their violence. Although they were not representatives of nation-states, they sought to seize state power. This is how the master of this kind of warfare, Mao Tse-tung, revolutionised our understanding of the utility of force. No longer was it strategically used to serve an established government. Instead, by skilfully employing multifaceted campaigns on diverse lines of effort, unfolding in both tangible and intangible space, the insurgent could systematically build a counter-state that, when powerful enough, could challenge the incumbent in a conventional campaign, destroy it, and then fill the void by becoming the new state.[12] With People’s War, Mao broadened our understanding of warfare, taking it beyond that which served the status quo elites. But he also reinforced the Westphalian context, since the goal of the insurgent was always to become the nation-state.

Today, in contrast, we face a foe who rejects the (Western) Westphalian model, an enemy who is not interested in a war of self-determination in the classic sense of postcolonial independence. Instead, he fights for worldwide religious supremacy, and this is why there is so much talk of al-Qaeda and Associated Movements (AQAM) as representing the first global insurgency, and one we must counter with a global counterinsurgency.[13] His idea of self-determination is not tied to the nation-state, but to a global theocracy, the Caliphate, within which all shall be subject to the will of Allah, and not the will of the people.

It is likewise clear that the last element of Clausewitz’s Trinity must be reassessed in the case of an irregular threat group that is even more ambitious than Maoist People’s War would have us expect. We cannot represent AQAM as a nation-state military led by a commander serving the national interests of his government. This third part of the trinity is now populated by various types of actors. It consists of leaders such as bin Laden who say they serve no government, only God. It also consists of actors such as Abu Musab al-Zarqawi, a terrorist and insurgent leader who said he served God but also swore fealty (bay'at) to bin Laden. It also refers to domestic enemies such as Mohammad Sidique Khan, the British terrorist who masterminded the 7/7 attacks. And lastly, it can also refer to the likes of Anwar al-Awlaki, the Yemen-based, American Muslim cleric who may not have had classic command and control of the Fort Hood shooter and Nigerian Christmas Day bomber, but far more importantly acted as inspiration and sanctioning authority for both Major Nidal Malik Hassan and failed suicide bomber Umar Farouk Abdulmutallab.

Conclusion: Clausewitz is still valuable. His understanding of what war between states should look like has not changed with the arrival of a globally motivated and capable non-state actor using irregular tactics and strategies. Nevertheless, his trinity cannot be applied directly to such enemies. The context has changed. The world can no longer be described as consisting of solely the governed, the governing, and the regular militaries that serve them. It has become more complex.

Fortunately, Clausewitz’s other non-trinitarian insights into conflict still hold true. His image of war as two wrestlers is just as apt in describing Kennedy versus Khrushchev in 1962 as it is in representing General McChrystal versus the Quetta Shura today. This is the part of On War that we must re-emphasise, while de-emphasising and reframing his Wondrous Trinity. With an enemy who sees himself as divinely justified, the expression of war as a competition of wills is more important than ever before.

In this regard, Clausewitz emphasised will over capabilities. This emphasis is doubly applicable today; it is the only way we can explain how untrained and pathetically equipped irregulars can still challenge the best fighting force in the world despite all its Predators and real-time intelligence. Understanding this element of Clausewitz’s writings, Martin van Creveld warns that a ‘theory of war that only recognizes physical factors while ignoring moral and psychological ones is not worth the paper on which it is written’.

If we have the audacity to update the Prussian master’s trinity, we should perhaps renew our faith in his famous dictum, even while recognising how much we have misinterpreted it as of late. War may in fact serve politics as its extension in the Westphalian way of doing business, but we should also understand that war is politics, and politics is war. For too many years it is the violence –the kinetic effect– that has been our focus. Today, we face a foe who knows that war starts with ideas and depends on them, far more than it depends on weapons.
