The Olympics are about unity and diversity, not politics and profit. Boycotts don't work | Thomas Bach

Participating in the Olympic Games is an incredible experience for every athlete. But it is also humbling when you realise that you are part of something bigger. You are part of an event that unites the world. In the Olympic Games, we are all equal. Everyone respects the same rules, irrespective of social background, gender, race, sexual orientation or political belief.

The first time I experienced this magic was at the Olympic Games in Montreal in 1976. From the moment I moved into the Olympic Village, I could feel the Olympic spirit come alive. Living together with my fellow athletes from all over the world opened my eyes to the unifying power of sport. As athletes, we are competitors in sport, but in the Olympic Village, we all live peacefully together under one roof. Whenever Olympians meet, no matter where we are from or when we competed in the Games, this shared experience immediately becomes the topic of our conversations.

One incident clouded my first Olympic experience, however. Shortly before the opening ceremony, I looked outside the window of our room in the Olympic Village to see a large group of African athletes with packed bags. Many were in tears, others hung their heads in despair. After asking what was happening, I learned they had to leave because of a last-minute decision by their governments to boycott the Games. Their devastation at having their Olympic dream shattered at the last possible moment after so many years of hard work and anticipation still haunts me today.

This foreshadowed another defining moment four years later, when I experienced the political impotence of sport at the time of the boycott of the 1980 Moscow Olympics. As the chair of the West German athletes’ commission, I strongly opposed this boycott because it punished us for something that we had nothing to do with – the invasion of Afghanistan by the Soviet army. I had to realise that the sports organisations had very little, if any, political influence, while on the athlete side we had very little say. Our voices were heard neither by the politicians nor by our sports leaders. This was a very humiliating experience.

In the end, the National Olympic Committee of West Germany was one of many to boycott the Games. It is no consolation that we were ultimately proven right that this boycott not only punished the wrong ones, but that it also had no political effect whatsoever: the Soviet army stayed nine more years in Afghanistan. In fact, the 1980 boycott only triggered the revenge boycott of the following Olympic Games, Los Angeles 1984.

These two experiences still shape my thinking today. They made it clear to me that the central mission of the Olympic Games is to bring together the world’s best athletes from 206 NOCs in a peaceful sporting competition.

The Olympic Games are not about politics. The International Olympic Committee, as a civil non-governmental organisation, is strictly politically neutral at all times. Neither awarding the Games, nor participating, are a political judgment regarding the host country. The Olympic Games are governed by the IOC not governments. The IOC issues the invitation to national olympic committees to participate; the invitations do not come from the government of the host country. It is the NOC that then invites its political authorities to accompany their athletes to the Games. The host country’s head of state is only allowed to say one sentence, scripted by the IOC, to officially open the Games. No other politician is allowed to play any role whatsoever, not even during medal ceremonies.

The Olympic Games are not about making a profit. The IOC reinvests 90% of all its revenues in athletes around the world, particularly in developing countries. The money goes to the organisers of Olympic Games who give the athletes the stage to shine. The Olympics can only unite the entire world through sport if everyone can participate. This is why solidarity benefits all athletes in the world. Not just a few countries, or a few sports. Our money benefits all athletes from all 206 NOCs, from the IOC Refugee Olympic Team and from all Olympic sports, ensuring true universality and diversity.

The Olympic Games are firstly about sport. The athletes personify the values of excellence, solidarity and peace. They express this inclusiveness and mutual respect also by being politically neutral on the field of play and during the ceremonies. At times, this focus on sport needs to be reconciled with the freedom of speech that all athletes also enjoy at the Olympic Games. This is the reason there are rules for the field of play and the ceremonies protecting this spirit of sport. The unifying power of the Games can only unfold if everyone shows respect for and solidarity to one another. Otherwise, the Games will descend into a marketplace of demonstrations of all kinds, dividing and not uniting the world.

The Olympic Games cannot prevent wars and conflicts. Nor can they address all the political and social challenges in our world. But they can set an example for a world where everyone respects the same rules and one another. They can inspire us to solve problems in friendshipand solidarity. They can build bridges leading to better understanding among people. In this way, they can open the door to peace.

The Olympics are a reaffirmation of our shared humanity and contribute to unity in all our diversity. As I learned through personal experience, ensuring that the Olympic Games can unfold this magic and unite the entire world in peace is something worth fighting for every day.
