Helsinki Security Forum 2025

THE HOUR OF EUROPE

HSF 2025 asks ‘The Hour of Europe’

As the global environment faces rapid and disruptive changes, Europe’s ability to act is once again tested.

Helsinki Security Forum 2025 – The Hour of Europe offers a unique platform for high-level security and defence dialogue at a time when old certainties are fading and new challenges demand urgent responses.

Europe must move decisively by boosting competitiveness, investing in defence, and shaping a security order that reflects its own values and interests, says Hiski Haukkala, Director of the Finnish Institute of International Affairs.

“These are not optional ambitions – they are necessary responses to a world in flux that will not wait for Europe to catch up. The illusion of guaranteed protection or prosperity, whether through the transatlantic alliance or global stability, is sadly fading. These themes are all present in the HSF 2025 programme.”

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. Amid the shifts in the US policy, Europe has to find ways to enhance Ukraine’s support while offsetting the risks of the US further distancing from…

A more equal relationship? The new emerging transatlantic security deal

20.11.2025

Since the 2014 illegal annexation of Crimea by Russia, Europe and NATO have slowly returned to building conventional deterrence in Europe. The balance in the transatlantic relationship, however, has largely remained intact. While the US has been doing most of the heavy lifting at its own expense, European countries have wasted precious time reminiscing of…

Nordic military cooperation as an enabler and hedge

18.11.2025

Finland’s and Sweden’s NATO memberships have led to increasingly deep military cooperation among the Nordic countries, particularly within the “Fennoscandian trio” of Finland, Sweden, and Norway. NATO’s Nordic enlargement has brought strategic clarity to Northern Europe. Together, the Nordic countries form a uniquely coherent group of states that can serve both as a critical enabler…
