In my view, the debate between realism and idealism fundamentally misstates the problem, and this misstatement will play a critical role in the next decade. Either it will be resolved or the imbalance within U.S. foreign policy will become ever more evident. The idealist argument constantly founders on a prior debate between the right of national self-determination and human rights. The American Revolution was built on both principles, but now, more than two centuries later, what do you do when a country such as Germany determines through constitutional processes to abrogate human rights? Which takes precedence, the right to national self-determination or human rights? What do you do with regimes that do not hold elections like those in the United States but that clearly embody the will of the people based on long-standing cultural practice? Saudi Arabia is a prime example. How can the United States espouse multiculturalism and then demand that other people select their leaders the way people do in Iowa?
The realist position is equally contradictory. It assumes that the national interest of a twenty-first-century empire is as obvious as that of a small eighteenth-century republic clinging to the eastern seaboard of North America. Small, weak nations have clear-cut definitions of the national interest—which is primarily to survive with as much safety and prosperity as possible. But for a country as safe and prosperous as the United States—and with an unprecedented imperial reach—the definition of the national interest is much more complicated. The realist theory assumes that there is less room for choice in the near term than there is, and that the danger is always equally great. The concept of realism cannot be argued with as an abstract proposition—who wants to be unrealistic? Coming up with a precise definition of what reality consists of is a much more complex matter. In the sixteenth century, Machiavelli wrote, “The main foundations of every state, new states as well as ancient or composite ones, are good laws and good arms. You cannot have good laws without good arms, and where there are good arms, good laws inevitably follow.” This is a better definition of realism than the realists have given us.
I believe that the debate between realists and idealists is in fact a naive reading of the world that has held too much sway in recent decades. Ideals and reality are different sides of the same thing: power. Power as an end in itself is a monstrosity that does not achieve anything lasting and will inevitably deform the American regime. Ideals without power are simply words—they can come alive only when reinforced by the capacity to act. Reality is understanding how to wield power, but by itself it doesn’t guide you toward the ends to which your power should be put. Realism devoid of an understanding of the ends of power is frequently another word for thugishness, which is ultimately unrealistic. Similarly, idealism is frequently another word for self-righteousness, a disease that can be corrected only by a profound understanding of power in its complete sense, while realism uncoupled from principle is frequently incompetence masquerading as tough-mindedness. Realism and idealism are not alternatives but necessary complements. Neither can serve as a principle for foreign policy by itself.
Idealism and realism resolve themselves into contests of power, and contests of power turn into war. To turn once again to Machiavelli: “War should be the only study of a prince. He should consider peace only as a breathing-time, which gives him leisure to contrive, and furnishes an ability to execute, military plans.”
In the twentieth century, the United States was engaged in war 17 percent of the time—and these were not minor interventions but major wars, involving hundreds of thousands of men. In the twenty-first century, we have been engaged in war almost 100 percent of the time. The founders made the president commander in chief for a reason: they had read Machiavelli carefully and they knew that, as he wrote, “there is no avoiding war; it can only be postponed to the advantage of others.”
The greatest virtue a president can have is to understand power. Presidents are not philosophers, and the exercise of power is an applied, not an abstract, art. Trying to be virtuous will bring not only the president to grief but the country as well. During war, understanding power means that crushing the enemy quickly and thoroughly is kinder than either extending the war through scruples or losing the war through sentimentality. This is why conventional virtue, the virtue of what we might call the good person, is unacceptable in a president. Again as Machiavelli put it, “The fact is that a man who wants to act virtuously in every way necessarily comes to grief among so many who are not virtuous.”
Machiavelli introduces a new definition of virtue, which instead of personal goodness consists of being cunning. For princes, virtue is the ability to overcome fortune. The world is what it is, and as such, it is unpredictable and fickle, and the prince must use his powers to overcome the surprises the world will present. His task is to protect the republic from a world full of people who are not virtuous in any conventional sense.
Presidents may run for office on ideological platforms and promised policies, but their presidency is actually defined by the encounter between fortune and virtue, between the improbable and the unexpected—the thing that neither their ideology nor their proposals prepared them for—and their response. The president’s job is to anticipate what will happen, minimize the unpredictability, then respond to the unexpected with cunning and power.
From Machiavelli’s point of view, ideology is trivial and character is everything. The president’s virtue, his insight, his quickness of mind, his cunning, his ruthlessness, and his understanding of the consequences are what matters. Ultimately, his legacy will be determined by his instincts, which in turn reflect his character.
The great presidents never forget the principles of the republic and seek to preserve and enhance them—in the long run—without undermining the needs of the moment. Bad presidents simply do what is expedient, heedless of principles. But the worst presidents are those who adhere to principles regardless of what the fortunes of the moment demand.
The United States cannot make its way in the world by shunning nations with different values and regimes that are brutal, all the while carrying out exclusively noble actions. The pursuit of moral ends requires a willingness to sup with the devil.
I began this chapter by speaking of the tension between the American republic and empire in the decade ahead. Whatever moral scruples we might have about being an empire, this is the role history has cast us in. If the danger in becoming an empire is that we lose the republic, certainly the realist view of foreign policy would take us there, if not intentionally, then simply through indifference to moral issues. At the same time, idealists would bring down the republic by endangering the nation, not through intent but through hostility or indifference to power. Of course, the fall of the republic won’t occur in the next decade. But the decisions made during the next decade will profoundly affect the long-term outcome.
Over the next decade, the president won’t have the luxury of ignoring either ideals or reality. Instead he must choose the uncomfortable synthesis of the two that Machiavelli recommended. The president must focus not only on the accumulation and use of power but on its limits. A good regime backed by power and leaders who understand the virtue both of the regime and of power is what is required. This is not a neat ideological package that explains and reduces everything to simplistic formulas. Rather, it is an existential stance toward politics that affirms moral truths in politics without becoming their simpleminded prisoner, and that uses power without worshipping it.
