It is now 70 years after what was perhaps the most important trial in the history of mankind. What makes this circumstance particularly significant is that it was the first time in history that a murderous regime of a defeated state was put to trial by the victorious powers after a particularly cruel and vicious war. The defendants were tried for acts that confounded human understanding or were not considered criminal before 1945. The exception were those few cases that were prosecuted for war crimes after World War I.
Perhaps it would be easy to disparage Nuremberg saying that the defeated had been tried by the “victors’ justice.” What is certain, however, is that in international law nothing was the same after Nuremberg. The most important members of the Nazi government were charged with three offenses: crimes against peace, war crimes and crimes against humanity. Not included in the trials were Adolf Hitler, Heinrich Himmler and Joseph Goebbels, who had committed suicide before the trial’s commencement.
The first category — crimes against peace — was imposed at the insistence of the United States. This offense is perhaps the most critical since, until 1945, war was the common way of settling international disputes. Therefore, to charge as a crime something that had not been a crime before that date made the trial tainted by a layer of suspicion. As Joachim von Ribbentrop, former foreign minister of Nazi Germany (1938-1945), stated in 1945: “You’ll see. A few years from now the lawyers of the world will condemn this trial. You can’t have a trial without law.”
War crimes were violations of the war laws existing at the time of conflict. Nuremberg was going to be the last time — until the creation in 2000 of the International Criminal Court — that violations of the conventions establishing rights and obligations of combatants were the reason for a trial.
The last category, crimes against humanity, was the most original contribution of Nuremberg. It gave character to the trial and insured that, despite its flaws, it would retain a privileged place in world history. In this category were included the atrocious persecution and murder of millions of people by a fanatical and cruel regime. Even today, 70 years later, the atrocities committed by the Nazis move whoever analyzes them.
This category, however, affects a basic guarantee that supports the defendants during the trial: that of not being prosecuted for acts that were not considered crimes at the time of commission. However, both the International Military Tribunal and the 12 subsequent courts carried forward by the U.S. against all levels of the Nazi government demolished this argument with irrefutable proof that laid the foundations of the science of international criminal law.
The ones who ordered or participated in the pogroms, evacuations, mass murders, concentration camp internments and systematic elimination of millions of human beings on grounds of religion, race, sexual orientation or political views knew that what they were doing was contrary to the most essential notions of humanity.
The idea of a broader and comprehensive international law wore away the hitherto monolithic approach of state sovereignty and imposed on states a universal obligation. This was a fundamental pivot that changed the course of law. A few years later, the International Court of Justice, in a landmark ruling, acknowledged the existence of such obligations for all mankind. Petty dictators could no longer rely on the sovereignty and independence of their state to do whatever they wanted in their internal sphere. Some crimes breached national borders and became grievances against the whole of humanity.
Nuremberg undoubtedly had many flaws that were multiplied by the equivalent tribunal held in Tokyo the following year. It has left a crucial legacy, however, of the exaltation of human values as recognized for the first time by an international court that, although composed by the victors, stated an undeniable truth. Approximately 200 German war crime defendants were tried at Nuremberg, and 1,600 more were tried under the traditional channels of military justice.
Seventy years since the trial that pitted humanity against unleashed evil, we have witnessed hundreds of wars. Although those conflicts never had the number of victims of World War II, they are equal to it in their horror, as has happened in Rwanda, in the former Yugoslavia, and now in Syria and Yemen, to name just a few.
International tribunals were created specifically to punish those atrocities and stop conflicts. They were the necessary prelude to a larger and more ambitious project: the permanent installation of the International Criminal Court, which would prosecute and punish the most serious crimes committed since its inception.
Unfortunately, more than a decade after its creation the new court shows very poor results. It has proven to be subject to the vagaries of international politics and has only judged some individuals who have committed crimes in African national struggles. Forced migrations, wars against civilian targets and mass murders demand a proper response.
It is up to today’s leaders to keep “the spirit of Nuremberg” alive. For reviving its true sense of justice, however, active participation by the U.S. at the International Criminal Court will be necessary. However, Guantanamo, Abu Ghraib and other human rights abuses hinder the possibility that the U.S. will resume the leadership once shown in Nuremberg.
