RUSI's Future Euro-Atlantic Security Architecture research project will organise a series of events in London and Brussels to consider the fast-changing landscape of Europe's security architecture. A set of publications will also be produced that will analyse how the region’s leading security organisations are evolving to meet the new situation and identify where new political arrangements are emerging in response to gaps in security governance.

A particular focus for the project will be the role that nuclear policy and extended deterrence are playing in shaping Europe's evolving security architecture, including the place of arms control within the continent's security governance.

Aims and objectives

This project has been established to provide expertise, resources and processes to strengthen the UK government’s understanding of major and emerging threats to Euro-Atlantic strategic stability, along with evidence-based policy recommendations and strategic convenings to manage threats and prevent miscalculation and unintended escalation.

The effort is designed to increase collaboration between the UK and its allies and partners to build defence and deterrence capabilities and to promote increased support for rules and norms amongst a broader set of countries and multilateral organisations.
