The Nordic countries share broadly similar threat perceptions, focus on deterring Russia, and are increasingly aligning their defence doctrines. Finland’s and Sweden’s NATO memberships have led to increasingly deep military cooperation among the Nordic countries.

In his article, Nordic military cooperation as an enabler and hedge, Senior Research Fellow Matti Pesu examines the evolving Nordic defence cooperation in today’s shifting security environment.

"Together, the Nordic countries form a uniquely coherent group of states that can serve both as a critical enabler of NATO’s collective deterrence in Northern Europe and as a hedge against any reduction in the United States’ role in European security."

The article was first published as part of the HSF 2025 Report on September 2025. You can read the HSF Report below.

Sitting on a cliff: How Europe should enhance Ukraine’s security

28.11.2025

Over the last year Ukraine’s political and military position has been worsening. Moscow insists on its maximalist objectives and is determined to continue to pursue them through military means.
