GZERO World examines the current state of transatlantic partnerships between the US and Europe following four years of Trump's presidency, and whether or not the incoming Biden Administration can restore trust that the US is a willing and reliable ally. Ian Bremmer's guest is one of Germany's most accomplished diplomats, Wolfgang Ischinger, who has served as ambassador to both the US and the UK. His new book, World in Danger: Germany and Europe in an Uncertain Time, explores the current state of the EU and its place in global affairs as the UK prepares for its "BREXIT" and China looms large in the geopolitical landscape.
