The article looks at the history and enduring relevance of the Organization for Security and Co-operation in Europe (OSCE)'s First Dimension, which covers politico-military issues. Tracing the evolution from the Cold War period to the current rupture, it argues that while cooperative security has yielded to deterrence, the Helsinki Final Act's normative infrastructure remains essential for managing risk and preventing escalation. The analysis advocates a pragmatic shift toward basic risk reduction, leveraging the OSCE's "soft" assets and adapting existing instruments-such as the Vienna Document-to address emerging technologies for example armed Unmanned Aerial Vehicles (UAVs). Ultimately, preserving the OSCE acquis provides vital tools for navigating confrontation while safeguarding the foundations for future stability.
