The US withdrawing from the Paris Agreement, the Trans-Pacific Partnership, the ''Iran deal'', UNESCO, as well as the UN Human Rights Council: issues like these convey the impression that the world order has changed. Without US leadership, it may seem that we have entered into what Ian Bremmer, an oft-quoted political pundit, calls a G0 world, a world without any leadership. Clement Guitton argues against this world view, as it disregards evidence of global leadership around the world on matters ranging from climate change, to trade, to security. Going a step further, Guitton claims that there is even evidence of a new form of leadership in international affairs: group leadership.
