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. ==See also==
