Executive Summary
Federal Councillor Ignazio Cassis will represent Switzerland at the OSCE Ministerial Council meeting in Vienna on December 3-4, 2025, where European security and particularly the war in Ukraine will be the focus. As the incoming OSCE Chairperson for 2026, Switzerland will pursue five priorities: a just peace in Ukraine, inclusive multilateral diplomacy, human-centered technology governance, strengthening democratic values, and maintaining the OSCE's capacity to act. Switzerland's assumption of the chairmanship for the third time marks a decisive moment for the European security architecture.
Critical Guiding Questions
To what extent can Switzerland, as a neutral state, actually mediate a "just peace" in Ukraine when the conflicting parties have fundamentally different concepts of justice?
What concrete mechanisms could the OSCE develop under Swiss leadership to overcome its chronic underfunding and sustainably secure its ability to act?
How can Switzerland use its diplomatic tradition to promote inclusive dialogue without compromising fundamental principles such as the territorial integrity of states?
Scenario Analysis: Future Perspectives
Short-term (1 year): Switzerland will host the 2026 OSCE Ministerial Council meeting in Lugano and position itself as a bridge-builder between hardened fronts. Expectations for concrete breakthroughs in the Ukraine conflict remain subdued, while the focus is placed on pragmatic cooperation in less contentious areas.
Medium-term (5 years): Under Swiss impetus, the OSCE could develop new formats for security dialogues that remain functional even in times of geopolitical tensions. The linking of science and diplomacy on technology issues could become a lasting legacy of the Swiss chairmanship.
Long-term (10-20 years): The dialogue mechanisms established during the Swiss chairmanship could become the foundation for a new European security architecture that is resilient to geopolitical crises. The OSCE could establish itself as a central forum for technological governance in Europe.
