Grand strategy

Grand strategy or high strategy is a state's strategy of how means (military and nonmilitary) can be used to advance and achieve national interests in the long-term. Issues of grand strategy typically include the choice of military doctrine, force structure and alliances, as well as economic relations, diplomatic behavior, and methods to extract or mobilize resources.

In contrast to strategy, grand strategy encompasses more than military means (such as diplomatic and economic means); does not equate success with purely military victory but also the pursuit of peacetime goals and prosperity; and considers goals and interests in the long-term rather than short-term.

In contrast to foreign policy, grand strategy emphasizes the military implications of policy; considers costs benefits of policies, as well as limits on capabilities; establishes priorities; and sets out a practical plan rather than a set of ambitions and wishes. A country's political leadership typically directs grand strategy with input from the most senior military officials. Development of a nation's grand strategy may extend across many years or even multiple generations.

Much scholarship on grand strategy focuses on the United States, which has since the end of World War II had a grand strategy oriented around primacy, "deep engagement", and/or liberal hegemony, which entail that the United States maintains military predominance; maintains an extensive network of allies (exemplified by NATO, bilateral alliances and foreign US military bases); and integrates other states into US-designed international institutions (such as the IMF, WTO/GATT, and World Bank). Critics of this grand strategy, which includes proponents for offshore balancing, selective engagement, restraint, and isolationism, argue for pulling back.

Definition

There is no universally accepted definition of grand strategy. One common definition is that grand strategy is a state's strategy of how means (military and nonmilitary) can be used to advance and achieve national interests in the long-term.

Grand strategy expands on the traditional idea of strategy in three ways:

expanding strategy beyond military means to include diplomatic, financial, economic, informational, etc. means
examining internal in addition to external forces – taking into account both the various instruments of power and the internal policies necessary for their implementation (conscription, for example)
including consideration of periods of peacetime in addition to wartime

Thinkers differ as to whether grand strategy should serve to promote peace (as emphasized by B. H. Liddell Hart) or advance the security of a state (as emphasized by Barry Posen).

History

In antiquity, the Greek word "strategy" referred to the skills of a general. By the sixth century, Byzantines distinguished between "strategy" (the means by which a general defends the homeland and defeats the enemy) and "tactics" (the science of organizing armies). Byzantine Emperor Leo VI distinguished between the two terms in his work Taktika.

Prior to the French Revolution, most thinkers wrote on military science rather than grand strategy. The term grand strategy first emerged in France in the 19th century. -->

Roman Empire

From the era of Hadrian, Roman emperors employed a military strategy of "preclusive security—the establishment of a linear barrier of perimeter defence around the Empire. The Legions were stationed in great fortresses". These "fortresses" existed along the perimeter of the Empire, often accompanied by actual walls (for example, Hadrian's Wall). Due to the perceived impenetrability of these perimeter defenses, the Emperors kept no central reserve army. The Roman system of roads allowed for soldiers to move from one frontier to another (for the purpose of reinforcements during a siege) with relative ease. These roads also allowed for a logistical advantage for Rome over her enemies, as supplies could be moved just as easily across the Roman road system as soldiers. This way, if the legions could not win a battle through military combat skill or superior numbers, they could simply outlast the invaders, who, as historian E.A. Thompson wrote, "Did not think in terms of millions of bushels of wheat."

The emperor Constantine moved the legions from the frontiers to one consolidated roving army as a way to save money and to protect wealthier citizens within the cities. However, this grand strategy, according to some ancient sources, had costly effects on the Roman empire by weakening its frontier defenses and allowing it to be susceptible to outside armies coming in. Also, people who lived near the Roman frontiers would begin to look to the barbarians for protection after the Roman armies departed. This argument is considered to have originated in the writings of Eunapius. As stated by the 5th century AD historian Zosimus:

This charge by Zosimus is considered to be a gross exaggeration and inaccurate assessment of the situations in the fourth century under Constantine by many modern historians. B.H. Warmington, for instance, argues that the statement by Zosimus is "[an] oversimplification," reminding us that "the charge of exposure of the frontier regions is at best anachronistic and probably reflects Zosimus' prejudices against Constantine; the corruption of the soldiers who lived in the cities was a literary commonplace."

World War II

An example of modern grand strategy is the decision of the Allies in World War II to concentrate on the defeat of Germany first. The decision, a joint agreement made after the attack on Pearl Harbor (1941) had drawn the US into the war, was a sensible one in that Germany was the most powerful member of the Axis, and directly threatened the existence of the United Kingdom and the Soviet Union. Conversely, while Japan's conquests garnered considerable public attention, they were mostly in colonial areas deemed less essential by planners and policy-makers. The specifics of Allied military strategy in the Pacific War were therefore shaped by the lesser resources made available to the theatre commanders.

Cold War

The US and the UK used a policy of containment as part of their grand strategy during the Cold War.

In the United States

The conversation around grand strategy in the United States has evolved significantly since the country's founding, with the nation shifting from a strategy of continental expansion, isolation from European conflicts, and opposition to European empires in the Western hemisphere in its first century, to a major debate about the acquisition of an empire in the 1890s (culminating in the conquest of the Philippines and Cuba during the Spanish–American War), followed by rapid shifts between offshore balancing, liberal internationalism, and isolationism around the world wars. The Cold War saw increasing use of deep, onshore engagement strategies (including the creation of a number of permanent alliances, significant involvement in other states' internal politics, and a major counterinsurgency war in Vietnam.) With the end of the Cold War, an early strategic debate eventually coalesced into a strategy of primacy, culminating in the invasion of Iraq in 2003. The aftershocks of this war, along with an economic downturn, rising national debt, and deepening political gridlock, have led to a renewed strategic debate, centered on two major schools of thought: primacy and restraint. A return to offshore balancing has also been proposed by prominent political scientists Stephen Walt and John Mearsheimer.

In the 1990s

The end of the Cold War and the collapse of the Soviet Union removed the focal point of U.S. strategy: containing the Soviet Union. A major debate emerged about the future direction of U.S. foreign policy. In a 1997 article, Barry R. Posen and Andrew L. Ross identified four major grand strategic alternatives in the debate:

neo-isolationism
selective engagement
cooperative security
primacy

Neo-isolationism

Stemming from a defensive realist understanding of international politics, what the authors call "neo-isolationism" advocates the United States remove itself from active participation in international politics in order to maintain its national security. It holds that because there are no threats to the American homeland, the United States does not need to intervene abroad. Stressing a particular understanding of nuclear weapons, the authors describe how proponents believe the destructive power of nuclear weapons and retaliatory potential of the United States assure the political sovereignty and territorial integrity of the United States, while the proliferation of such weapons to countries like Britain, France, China and Russia prevents the emergence of any competing hegemon on the Eurasian landmass. "It steers the middle course between an isolationist, unilateralist course, on the one hand, and world policeman, highly interventionist role, on the other." Stressing the importance of world peace and international cooperation, the view supposes the growth in democratic governance and the use of international institutions will hopefully overcome the security dilemma and deter interstate conflict. Posen and Ross "One argument, which I label 'geoeconomic favoritism,' hypothesizes that the military hegemon will attract private capital because it provides the greatest security and safety to investors. A second argument posits that the benefits from military primacy flow from geopolitical favoritism: that sovereign states, in return for living under the security umbrella of the military superpower, voluntarily transfer resources to help subsidize the cost of the economy. The third argument postulates that states are most likely to enjoy global public goods under a unipolar distribution of military power, accelerating global economic growth and reducing security tensions. These public goods benefit the hegemon as much, if not more, than they do other actors." "It makes enemies almost as fast as it slays them, discourages allies from paying for their own defense, and convinces powerful states to band together and oppose Washington's plans, further raising the costs of carrying out its foreign policy."

Ikenberry, Brooks, and Wohlforth are not convinced that the current U.S. grand strategy generates subsequent counterbalancing. Unlike the prior hegemons, the United States is geographically isolated and faces no contiguous great power rivals interested in balancing it. This means the United States is far less threatening to great powers that are situated oceans away, the authors claim. Moreover, any competitor would have a hard time matching U.S. military might. "Not only is the United States so far ahead militarily in both quantitative and qualitative terms, but its security guarantees also give it the leverage to prevent allies from giving military technology to potential U.S. rivals. Because the United States dominates the high-end defense industry, it can trade access to its defense market for allies' agreement not to transfer key military technologies to its competitors." Adherence to the light switch model, Carpenter argues, reflects intellectual rigidity or an effort to stifle discussion about a range of alternatives to the status quo. Selective engagement is a strategy that sits in between primacy and isolationism and, given growing multipolarity and American fiscal precariousness, should be taken seriously. "Selectivity is not merely an option when it comes to embarking on military interventions. It is imperative for a major power that wishes to preserve its strategic insolvency. Otherwise, overextension and national exhaustion become increasing dangers." America would take advantage of what Posen calls a "remarkably good" strategic position: "[The United States] is rich, distant from other great powers, and defended by a powerful nuclear deterrent. Other great powers are at present weaker than the United States, close to one another, and face the same pressures to defend themselves as does the United States." Proponents of strategic restraint argue, consistent with the realist tradition, that states are self-interested and accordingly will look out for their own interests and balance against aggressors; however, when possible, states prefer to "free ride" or "cheap ride," passing the buck to other states to bear the cost of balancing. Restraint proponents also emphasize the deterrent power of nuclear weapons, which tremendously raise the stakes of confrontations between great powers, breeding caution, rather than rewarding aggression. Restraint advocates see nationalism as a powerful force, one that makes states even more resistant to outside conquest and thus makes the international system more stable. Restraint proponents also argue, drawing on thinkers like the Prussian strategist Carl von Clausewitz, that military force is a blunt, expensive, and unpredictable instrument, and that it accordingly should only be used rarely, for clear goals.

Restraint is distinct from isolationism: isolationists favor restricting trade and immigration and tend to believe that events in the outside world have little impact within the United States. As already noted, it is sometimes confused with non-interventionism. Restraint, however, sees economic dynamism as a key source of national power and accordingly tends to argue for a relatively open trade system. Some restrainers call for supporting this trade system via significant naval patrols; others suggest that the international economy is resilient against disruptions and, with rare exceptions, does not require a powerful state to guarantee the security of global trade.

Offshore balancing

In offshore balancing, the United States would refrain from significant involvement in security affairs overseas except to prevent a state from establishing hegemony in what offshore balancers identify as the world's three key strategic regions: Europe, Northeast Asia, and the Persian Gulf. This strategy advocates a significantly reduced overseas presence compared to liberal hegemony, but argues that intervention is necessary in more circumstances than restraint. Offshore balancing is associated with offensive realist theories of state behavior: it believes that conquest can often enable states to gain power, and thus that a hegemon in regions with large economies, high populations, or critical resources could quickly become a global menace to U.S. national interests.
