In this chapter we look at the transnational and domestic conflict configurations among the citizen publics of sixteen member states. In terms of transnational conflicts, we find the expected opposition between the frontline states (Greece, Italy) and the V4 countries (augmented by eastern European bystander states). The contrasting stance of the policymakers from these countries during the refugee crisis is reflected in their voters’ positions. By contrast, citizens from western European destination, transit, and bystander states generally take more moderate positions. At the domestic level, we find the expected opposition between nationalists and cosmopolitans politically articulated by the radical right on the one side and by the left on the other side. Furthermore, as transnational conflicts are ultimately rooted in domestic conflict structures, the domestic polarization appears to be more intense than the transnational one. These results underscore that the conflict potentials of immigration policies have not yet been fully mobilized and, given the large opposition to immigration in some member states, may prove to become major obstacles to joint solutions.
