On 19 April, Ambassador Greminger participated in Professor Fred Tanner’s class on the role of European regional institutions during times of war. He shared his valuable insights with MINT on the OSCE, its range of crisis management instruments, and the limitations they face due to host states' trepidations or vetoes by third states. Ambassador Greminger emphasised the importance of empowering and resourcing the Executive Structures of the OSCE for crisis response, as well as the need for a Strategic Policy Support Unit to assist the Secretary General in advising the Chairmanship/Troika.

During the class, students presented their perspectives on the various reform options for the OSCE, ranging from a return to the Helsinki diplomacy process (CSCE), an OSCE à la carte, to a Helsinki+50 summit in 2025. Through the interactive discussion between the students and Ambassador Greminger, it clearly emerged that the role of the OSCE remains relevant, including through field missions and the ongoing work of the OSCE autonomous Institutions, such as the Office for Democratic Institutions and Human Rights (ODIHR). Drawing lessons from field missions like the Special Monitoring Mission to Ukraine (SMM) for future peace missions will be important. Above all, the outcome of Russia’s war on Ukraine will shape the future of European peace and security order, as well as the role of the OSCE.
