oday, we know US President Barack Obama and German Chancellor Angela Merkel as two of the world’s most influential leaders, together at the center of some of the biggest controversies and most impressive advancements of our time. But while their friendship has been the subject of both scrutiny and admiration, few know the full story. Taking office at the height of the 2008 global recession, Obama was keenly aware of the fractured relationship between the US and Europe. And for her part, Merkel was suspicious of the charismatic newcomer who had captivated her country. Faced with the challenges of globalization, the two often clashed over policy, but—as the first Black president and first female chancellor—they shared a belief that democracy could uplift the world.
