Abstract

This paper studies variation in mass attitudes towards the Russo-Ukrainian War. Although most Europeans express dismay at Russia’s aggression against Ukraine, more ambivalent or even pro-Kremlin positions are not rare. Drawing on the literature on foreign policy and war, we hypothesise that support for the aggressor may stem from a quartet of factors: economic interests, ideological preferences, partisan alignment, and disinformation. We examine the role of these factors using two types of survey data. The first is an original survey conducted in five countries (Czechia, France, Poland, Romania, and Slovakia) and spanning over 12,000 respondents. The second is the Solidarity in Europe survey, with more than 24,000 respondents from seventeen countries. The results of three types of analyses reveal that neutral and pro-Kremlin attitudes, held by sizeable segments of European society, are most strongly linked to the positions of respondents’ preferred political parties, followed by disinformation and ideology. Overall, top-down models of public opinion seem to better explain within-country variations in attitudes towards the conflict than bottom-up models. These findings, which should be interpreted with caution, carry important implications for containing Russia’s influence on European public opinion and contribute to the literature on public preference formation in the field of foreign policy.

Figure 1. Figure 1 long description.Responsibility for the war: overview.Note: 0 means ‘not at all responsible’ and 10 means ‘totally responsible.’ Total N for each question is 12,221. Respondents were not offered a ‘don’t know’ option.

Figure 2. Figure 2 long description.Responsibility for the war: Ukraine vs Russia.Note: The figure shows average differences in perceptions of Russia’s and Ukraine’s responsibility for the war. It draws on the first two rows from Figure 1. The resulting variable ranges from −10 to +10, but the country averages are all in the 0–5 interval. Positive values indicate greater blame on Russia. 95% confidence intervals.

The coefficients indicate changes in the probability of preferring Ukraine’s victory (over any other outcome) resulting from one-unit changes in the independent variables (holding other variables at their observed values). 95% confidence intervals.

News Consumption, Conservative Authoritarianism). Other variables are left at observed values. 95% confidence intervals.

The figure shows the country averages on the dependent variable which ranges from −10 to +10. Positive values indicate that respondents attribute stronger responsibility to Russia. 95% confidence intervals. Total N = 24,261.
