Finland’s official entry into NATO on 4 April 2023 marked the culmination of a meticulously orchestrated 11-month accession process, catalysed by the destabilising events surrounding the Russian invasion of Ukraine. While Finland’s accession to NATO may appear straightforward, it was expedited in light of the urgent security imperatives prompted by the invasion. Nevertheless, the transition to NATO membership calls for careful consideration of the multifaceted security dynamics between Finland and the alliance. In this context, this paper endeavours to cast a forward-looking perspective, examining the future trajectory of NATO-Finnish cooperation post-accession. Concretely, it will look at what the next steps are that NATO and Finland could and/or should take after the latter’s accession to the former.
Central to this exploration is an assessment of the potential avenues for Finland to further integrate into NATO’s operational framework. Specifically, a detailed analysis will be undertaken to evaluate the feasibility and implications of expanding NATO’s presence within Finnish territory through initiatives such as the enhanced forward presence (eFP). Then, the paper will explore the prospects for enhanced collaboration within the Northern Group, leveraging Finland’s NATO membership to deepen regional defence cooperation. Furthermore, consideration will be given to the merits of Finland joining the Bucharest Nine (B9) group, elucidating the potential benefits and strategic imperatives associated with such a move.
