The victory for Donald Trump followed the success of Rodrigo Duterte in the Philippines in a year that also saw Putin and Erdogan continue their authoritarian hold in Russia and Turkey respectively, and far-right movements make further advances across Europe. Yet, in terms of the wider effects on the nature of world order, the Brexit vote was even more significant. Whatever the long-term consequences are of British withdrawal from the EU, the form and content of the campaign itself saw populist and nationalist sentiment challenge the legitimacy of regionalism and globalism¿two cornerstones of governance in the contemporary era. This article will look at the significance of these moves in relation to world order and suggest that while the current turn towards nationalism and against globalism is significant, it will not necessarily lead to a significant change.
