Support for Ukraine against Russian aggression has been strong across Europe, but it is far from uniform. An expert survey of the positions taken by political parties in 29 countries conducted mid-2023 reveals that 97 of 269 parties reject one or more of the following: providing weapons, hosting refugees, supporting Ukraine's path to European Union membership, or accepting higher energy costs. Where the perceived threat from Russia is most severe, we find the greatest levels of support for Ukraine. However, ideology appears to be far more influential. The level of a party's populist rhetoric and its European Union skepticism explain the bulk of variation in support for Ukraine despite our finding that many strongly populist and European Union-skeptical parties take moderate pro-Ukraine positions when in government.
