Populism and cosmopolitanism, which one is invidious?

 In the last two decades, migration crisis and the populist reactions to migration and domestic economic issues have been the defining traits of a new political constellation. The traditional issue of the contrast between nationalism and cosmopolitanism has changed its profile: the current drastic contrast is between populist aversion to the foreigners-migrants and a more generous, or simply just, attitude of acceptance and Samaritan help. The populist aversion inherits some features traditionally associated with patriotism and nationalism, and the opposite attitude the main features of traditional cosmopolitanism. One could expect that the work on nationalism will be moving further on this new and challenging playground, addressing the new contrast and trying to locate nationalism in relation to it.
