Perhaps, in the future...
The country which has a 1,340-kilometer long border with Russia has to pay attention to Moscow's possible reaction: joining NATO can be perceived by the Kremlin as part of an influence game to deter Russia. What cannot also be neglected by the Finnish government in its calculations is that, as pointed out by Vladimir Putin during his state visit to Finland in 2016, "NATO would gladly fight Russia to the last Finnish soldier".[10] This image is bringing back the deep-seated Finnish memories of standing alone against the USSR in 1939-40 despite France's vague allusions of assistance. The Finns do not want to become too reliant on the Alliance to deter external military aggression because of this unpleasant experience, and especially when such a reliance is likely to lead to aggression.
Besides, Finland's alignment with NATO can lead not only to an escalation of political tension and public discontent, but also to a growth of military expenditures that Finland is not interested in. The Finns would then have to remember about committing at least 2% of their GDP to defense spending by 2024, while in 2019 it was only about 1.29% of GDP.[11,12] Not all the taxpayers will agree with that this is necessary, in particular considering the effects of the Coronavirus epidemic that is making shrink many of the world's economies and possibly also defense budgets.[13]
It is apparent today that the formal membership of Finland is achievable in theory but is not politically feasible in the near future. "Finnish government and politicians will take into account the public opinion. Yes, there are some supporters for NATO membership in Finland, so some politicians do express this opinion. Nevertheless, for as long as there is no substantial part of Finnish society that supports NATO membership, the Finnish government will avoid making this move. Moreover, the current level of cooperation between Finland and NATO means membership de facto but without any obligations in the face of partners".

That being said, Helsinki does not cease to contribute to the other defense capabilities, like supporting the EU's Common Security and Defence Policy.[14] Finland is engaged in the OSCE, the Nordic Council and other organizations – they can also provide the assistance if needed. These contribute to the stability and security in Europe and the membership therein does not provoke any tensions between Helsinki and Moscow. As for NATO, it seems that the process of convergence and cohesion will continue, but there is no evidence that Finland will ultimately become a formal member. After all, it might actually be a reasonable idea to maintain the status quo, steering a middle course.
