Expert Perceptions of Foreign Policy Strategies in Estonia, Hungary, and Greece: Orientations Before and After the Russia–Ukraine War

This file contains the aggregated results of an expert survey on foreign policy strategies in Estonia, Hungary, and Greece before and after the outbreak of the Russia–Ukraine war. The survey was conducted as part of the University of Pécs funded project Competing Foreign Policy Strategies on the EU’s Eastern Flank Before and After the Outbreak of the Russia–Ukraine War (project code: 009_2025_PTE_RK/12), which examines small state responses along the EU’s eastern border to the Russia–Ukraine war.

Data were collected through LimeSurvey between 13 February and 13 March 2026. Potential respondents were identified through Google Scholar searches based on their publications on the foreign policy of Estonia, Hungary, or Greece. Selected experts were invited by email, with follow-up reminder messages sent during the fieldwork period. Invitees could open the survey and indicate lack of relevant expertise; in such cases, the questionnaire automatically terminated.

The original target was 150 experts (50 per case study), and the file contains 44 valid responses. The dataset includes respondent background variables, specifically professional seniority, country of origin, and country of expertise, as well as aggregated responses to questions on pre-2022 and post-2022 foreign policy orientations, small state behavior, support for Ukraine, positions within the EU and NATO, energy diversification, and relations with Russia, China, and the transatlantic alliance.
