Abstract:
Finland’s entry into NATO marked admission to a nuclear alliance. The aim of this report is to provide an overview of the structure and trends of the international nuclear order, the basics of NATO’s nuclear deterrence and its implementation, and decision-making related to the alliance’s nuclear weapons policy. The study will also assess how Finland can participate in NATO’s nuclear deterrence policy if it so wishes and what effects NATO membership will have on Finland’s arms control policy. Nuclear deterrence constitutes one part of NATO’s deterrence mix, and the alliance views nuclear weapons as the supreme guarantee of its security. U.S. nuclear weapons form the backbone of NATO’s nuclear deterrence, and a small proportion of its nuclear weapons are stationed in allied countries. According to NATO’s statements, the purpose of its nuclear deterrence is to preserve peace, prevent coercion and deter military aggression. NATO has not made any major changes in its nuclear weapons policy in recent years. The key outlines of NATO’s nuclear weapons policy are decided at NATO summits. The alliance has its own senior body for discussion on nuclear weapons: the Nuclear Planning Group. Non-nuclear allies such as Finland have several opportunities to influence and participate in the alliance’s nuclear weapons policy. Importantly, as a member of NATO, Finland can continue its active arms control efforts.

Abstract:
The Russian war of aggression has rendered Northern Europe an increasingly significant region for Euro-Atlantic security. A stable and secure Northern Europe is a critical precondition for a safe and stable Euro-Atlantic region. The alliance should treat Northern Europe as a strategic whole although the different subareas of Northern Europe have their distinctive security dynamics and concerns. NATO is currently improving its deterrence and defence posture. It is simultaneously shifting its military strategy from a model of deterrence by reinforcement to one of deterrence by denial. NATO’s evolving posture and strategy in Northern Europe should be underpinned by a more explicit division of labour. The regional allies and stakeholders can be divided into four categories in terms of their role in regional security: frontline nations, hubs, security providers and the ultimate security guarantor. The regional frontline nations include the Baltic states, Finland and Poland, which can also play a role as hubs and even security providers along with the United Kingdom and Germany. Denmark, Sweden and Norway are first and foremost hubs. The United States remains the ultimate security guarantor of the area.

3. Finland in a nuclear alliance: Recalibrating the dual-track mindset on deterrence and arms control

Abstract:
Finland’s NATO bid was partly triggered by a sense of susceptibility to nuclear coercion. Seeking the protection of extended nuclear deterrence was seen as necessary to maximize Finnish security. The Finnish domestic environment is rather permissive towards Finland’s contribution to NATO’s nuclear deterrence policy. That said, nuclear deterrence may become a topic of debate as Finnish NATO policy evolves. Finland has several options in its contribution to NATO’s nuclear deterrence policy, ranging from a passive low-ambition strategy to medium- and high-ambition approaches. Finnish historical affinity with the non-proliferation regime will likely continue to characterize its nuclear disarmament policy as a NATO member. Although the time is not currently ripe for new arms control proposals, Finland has a self-interest in promoting NATO’s efforts in nuclear arms control, disarmament and non-proliferation.

Abstract:
One of the most notable consequences of the end of the Cold War was the diminished role of nuclear weapons in international relations. The world’s primary nuclear weapon powers, the United States and the Russian Federation, made considerable reductions in their nuclear forces. The climax of the process was the New START Treaty signed in 2010. Now, the optimism that characterized the first decades of the post-Cold War era is rapidly evaporating. Geopolitical competition again dominates global and regional security dynamics. Nuclear powers are modernizing their forces and introducing novel systems that may affect strategic stability. At the same time, existing arms control regimes are crumbling. This report takes stock of recent developments in deterrence in general, and nuclear deterrence in particular. Its main ambition is to understand how deterrence has changed in light of certain post-Cold War trends. To this end, the report introduces the basic principles of deterrence. It also explores the nuclear-related policies and capabilities of the four nuclear weapon states most directly involved in European security affairs – Russia, the United States, France, and the United Kingdom. Importantly, the report also analyses the implications of the recent trends in strategic deterrence for Northern Europe. This report is part of a research project conducted by the FIIA entitled ‘New Challenges for Strategic Deterrence in the 21st Century’. The project is part of the implementation of the Government Plan for Analysis, Assessment and Research 2018.
