These are the issues of our time: climate change, migration, terrorism, nuclear weapons, racist violence. These are the topics that Barack Obama pursued like no other statesman during his eight years as US President. In his speeches, he calmly and thoughtfully draws lessons from a misguided past policy and looks towards the future. Barack Obama is not only a sharp-minded politician; he is also one of those people who do not shy away from showing compassion, despair, and sorrow. His speech at Nelson Mandela's funeral and his spontaneous remarks on the Orlando shooting are unforgettable. His legacy is built on his speeches, which emphasize the importance of not betraying ideals even in the face of a difficult reality.
