This article zooms in on the pre-conditions on the citizens level for deeper Nordic cooperation on civil defence matters. Historical ties, Nordic security cooperation, high-trusting citizens, and the fact that all five Nordic states now are members of NATO speak in favour of increased cooperation on civil defence. Still, the experiences from the Covid 19-pandemic with different strategies, diverging policies and closed borders, as well as heated exchanges of views, provide us with contradicting expectations. Based on a unique dataset with over 11 000 Nordic respondents we address these mixed expectations and study the trust of the Nordic citizens in both their respective government’s civil defence preparedness, as well as the citizens’ preferences regarding Nordic and other forms of international cooperation in this area. The results show a significant variation of trust in the civil preparedness of national governments (Finland highest trust, Sweden lowest trust). The variation returns in the desire for deeper international cooperation with considerably lower level of support for enhanced Nordic cooperation among the Danish respondents, and strong support for such cooperation among the Finns, Norwegians, and Swedes. Hence, our results indicate a potential for enhanced cooperation among some Nordics, but not all.
