The hallmark of the Donald Trump administration's National Security Strategy (NSS), which was released in December, is the idea of "principled realism." This marks a decided shift from the policies of Trump's two immediate predecessors. President Bush, with his expansive freedom agenda, set a high priority on the use of U.S. power to promote liberty and democracy. President Obama, less committed to the idea of American exceptionalism and more doubtful of the value of the American role in the world, sought to disengage and "lead from behind." The Trump NSS, by contrast, represents a return to realism.
In his valuable book Realpolitik: A History, the British historian John Bew explains that realpolitik, or realism, was not, as often characterized today, an amoral approach to foreign policy. Instead, it arose in the nineteenth century in Germany, where figures such as Ludwig von Rochau, who believed in classical liberalism and who participated in the 1848 revolution, struggled to define a foreign policy that was true to their ideals but also cognizant of the limits of their power vis-a-vis states and empires ruled by authoritarians. As Bew puts it, realists focused on the question of "how to achieve liberal enlightened goals--which included balance and equilibrium--in a world that did not follow liberal enlightened rules."
How has the Trump administration sought to resolve this dilemma? First, it has avoided the trap of equating strategy with a wish list of goals, disconnected from the realities and limits of power.
In the past, the NSS document has often consisted of bottom-up aggregations of policies, which were essentially just stapled together and labeled a strategy, but did not comprise actual conceptual frameworks or orderings of priorities. The administration deserves credit for undertaking this strategy process early on.
In fact, the new NSS is the first serious top-down, government-wide strategy produced since the well-known Defense Policy Guidance (DPG) produced by the Pentagon in 1992, after the end of the Cold War. While the DPG--which I played a key role in formulating--was not embraced as a national-security strategy by the George H. W. Bush administration, many of its concepts shaped subsequent strategy documents and policies.
Second, the Trump administration took a clear-eyed look at world politics and at how we are currently positioned. In 1992, we had arrived at a unipolar moment at the end of the Cold War. The United States was preeminent, and the issue was how to consolidate that preeminence, preclude the rise of a global rival and prevent the domination of critical regions by hostile powers. That brief unipolar era is over.
Today, in critical regions, the mission of interstate competition has returned. China, Russia and Iran now present competitive challenges to the United States and its allies and partners. Beijing, by virtue of its dynamic economy, military buildup and assertive maritime claims, is the primary strategic competitor. Russia seeks to dominate its periphery. North Korea not only seeks coercive leverage over South Korea and Japan, but also is on the verge of being able to threaten American population centers with nuclear weapons. Also, regional and global trends have made many regions unstable, producing streams of refugees that in turn have had major political impacts. Threats from nonstate actors such as international terrorists, at times sponsored by hostile states, have grown.
Third, implicitly and sometimes explicitly, the new NSS identifies strategic errors by which the United States has contributed to today's challenges. At times the United States has recklessly disengaged, while at other times it has rushed forward with inadequately thought-through plans, or failed to take advantage of the golden hour presented by its actions. In still other instances, the United States has failed to preclude emerging threats in a timely manner. Often, it naively believed that the political systems of adversaries would converge with American values, or that generous arms-control or trade deals would induce other countries to follow the U.S.-led international order. These mistakes crossed party lines and involved both the executive and legislative branches. As a result, the balance of power in key regions shifted toward adversarial powers.
Fourth, the Trump administration has struck a new, cogent position in the perpetual debate about whether the United States' foreign policy should be guided by the national interest or the country's values and ideals. The Trump doctrine, reflective of a nation that is questioning the wisdom of some recent international ventures, suggests that the balance has shifted in favor of interests.
