I take no sides in this. I try to find the stories explaining things that happened and were reported at the time in one way or another and sometimes documents which are released decades later put certain things in certain perspectives.
I grew up in Switzerland and we had many migrants from Yugoslavia. I played football with them. They were my teammates. Ethnicity was no topic, a bit mocking here and there between all of us. Then the war broke out and it arrived in our team. We outsiders had no idea what was going on, but the sudden hate was unbelievable and each side tried to convince us that they were right. Many of them left the team and the rest of us speechless. It was all so sad.
