The United States, the Nuremberg Trials, and the Irony of Refusing the ICC
The Nuremberg Trials stand as one of the most consequential legal undertakings of the 20th century. Conducted in the aftermath of the Second World War, they created a new architecture for international criminal justice—naming, defining, and prosecuting crimes such as aggressive war, crimes against humanity, and genocide in ways the world had never formally attempted. At the center of this legal revolution was the United States. American prosecutors, judges, legal theorists, and political leaders played indispensable roles in designing, organizing, and administering the trials. Yet, in a historical twist rich with irony, the same nation that led the international community in its first effort to hold individuals accountable for mass atrocities never joined the permanent court inspired by those principles: the International Criminal Court (ICC), established in The Hague in 2002.
Understanding why the irony of refusing the ICC exists requires examining both the origins of modern international criminal law at Nuremberg and the political calculations that shaped American attitudes toward global legal institutions in the decades that followed.

America’s outsized role at Nuremberg
Although the Nuremberg Tribunal was technically an Allied institution—run jointly by the United States, United Kingdom, Soviet Union, and France—it was the United States that provided the bulk of the initiative and the institutional structure.
As early as 1942, American legal thinkers and government officials began planning how to address Axis atrocities. The U.S. War Department and Treasury Department advocated strongly for a trial-based approach, resisting British suggestions of summary executions. As a result, what emerged was a judicial model with transparent proceedings, rules of evidence, and a written charter outlining precise crimes and standards of guilt. American Supreme Court Justice Robert H. Jackson, appointed by President Harry Truman as Chief U.S. Prosecutor, became the intellectual architect of the trials. His vision was that the proceedings should not be a “victor’s vengeance,” but a demonstration that even the defeated deserved a fair process.
The trials themselves were heavily shaped by American prosecutorial practices. The emphasis on documentary evidence, the structure of cross-examinations, and the concept of conspiracy—especially as applied to the Nazi leadership—reflected U.S. legal traditions. Even the decision to hold the trials in Nuremberg, though symbolically linked to Germany’s Nazi rallies, was made feasible largely because the United States controlled the city after the war.
Beyond logistics and legal frameworks, the United States also saw Nuremberg as a crucial experiment. The U.S. was emerging from the war as a global superpower and saw itself as responsible for shaping a rules-based international order. Nuremberg allowed it to demonstrate moral leadership and create a legal precedent that states—and individuals—could be held accountable to standards higher than national sovereignty.
The birth of modern international criminal law
Nuremberg contributed the foundational ideas that later shaped international criminal justice. It established that:
Individuals, not only states, can be held liable for international crimes.
“Following orders” is not a defense for atrocities.
Crimes against humanity are violations against all humankind, not just the victims.
These principles inspired later ad hoc tribunals—including those for Yugoslavia and Rwanda—and eventually informed the creation of the International Criminal Court.
In many ways, the ICC is the institutional descendant of Nuremberg. It embodies the idea that mass atrocities should not go unpunished and that a permanent mechanism should exist to prevent the need to build special tribunals after each crisis. Given that legacy, one might assume that the United States would enthusiastically join such a court. But it did not.
America and the irony of refusing the ICC: a relationship defined by caution and contradiction
The Rome Statute, the treaty that established the ICC, was adopted in 1998 and entered into force in 2002. The Clinton administration signed the treaty in its final days but never submitted it to the Senate for ratification. Two years later, the Bush administration took the unusual step of “unsigning” the treaty—formally withdrawing the United States’ intention to join.
The reasons stem from a mix of geopolitical concerns and domestic political dynamics:
1. Fear of politically motivated prosecutions
Successive U.S. administrations worried that the ICC might prosecute American military personnel or officials for actions taken abroad. As a global military power with extensive deployments, the United States was uniquely exposed to potential investigations. While supporters argued that the ICC’s safeguards make this unlikely, U.S. policymakers feared scenarios where adversaries could use the court to challenge U.S. foreign policy.
2. Commitment to constitutional sovereignty
American political culture contains a strong tradition of skepticism toward external constraints on U.S. decision-making. From the rejection of the League of Nations to hesitancy regarding UN obligations, this sovereignty-based caution has long shaped U.S. attitudes toward international law.
3. Domestic politics and ideological divides
Support for the ICC tends to align with liberal internationalism, while opposition is typically rooted in conservative nationalism. As administrations changed, the U.S. position shifted—but never enough to secure ratification.
4. The U.S. preference for ad hoc or hybrid tribunals
Despite refusing to join the ICC, the United States has supported many international criminal justice efforts—from Rwanda and Yugoslavia to Sierra Leone and Cambodia—when these aligned with U.S. strategic interests. This approach allows Washington to participate selectively without committing to a permanent supranational authority.
The irony of leadership without membership
The result is an irony many scholars have noted: the nation that pioneered the very idea of prosecuting individuals for international crimes has chosen not to join the institution built in Nuremberg’s image.
At Nuremberg, the United States championed the principle that no one, not even state leaders, should be above the law. America’s prosecutors insisted that civilization must reject “lawlessness in the name of state necessity.” And yet today, the U.S. remains outside the only permanent court dedicated to enforcing those principles globally.
But that irony also reflects the tensions inherent in the U.S. role as both a superpower and a promoter of global norms. The United States helped create international criminal law when the circumstances fit its vision of postwar order. The ICC, designed to be independent and universally applicable, represents a system the U.S. fears may one day judge its own actions.
Conclusion
The story of Nuremberg and the ICC illustrates the complexities of global governance and the contradictions of American foreign policy. The United States was the driving force behind the most important criminal tribunal in history—one that set the foundation for the ICC. Yet when the time came to commit to a permanent system of international justice, the U.S. stepped back.
The irony of refusing the ICC is undeniable: the country that helped define the principles of international accountability remains outside the court established to uphold them. Whether that stance will endure is uncertain, but the tension between America’s ideals and its strategic anxieties continues to shape the future of international criminal law.
