The world is in crisis. The risks from climate change, a renewed threat of nuclear weapons, the Long War on Terror, a refugee catastrophe and the possibility of ecological collapse have fed widespread anxieties about economic security and personal safety. Everywhere there is clamour for solutions, yet never have the options felt more restricted. On the one hand, there is the liberal order, which has brought us austerity, global corporatism and soaring inequality. On the other lies a return to majoritarian nationalism, which, unfettered by international institutions, helped lead humanity to two world wars.
