Rolf Nikel had largely finished his book when Russia invaded Ukraine. The former German ambassador to Poland had to start all over. Now he has published "Feinde, Fremde, Freunde" (Enemies, Strangers, Friends), a book about German-Polish relations. In conversation with Till Hoppe and Viktor Funk, Nikel stresses that Germany currently has a duty to build trust. But Poland also has to start working.
