{{Politics of Finland}}
[[Finland]] is one of six members of the European Union that are not members of NATO. Finland has had formal [[foreign relations of NATO|relations with NATO]] since 1994, when it joined the [[Partnership for Peace]] programme. The country maintains positive relations with the organisation and the [[enlargement of NATO|possibility of membership]] has been a topic of debate in the country since the end of the [[Cold War]]. Following the [[2022 invasion of Ukraine by Russia]], the debate turned in favour of NATO membership, and the [[Finnish President]] and [[Prime Minister of Finland|Prime Minister]] have declared that Finland should join NATO, with an application likely to be submitted in May 2022.

== Membership debate ==

=== History ===

Since the 1990s and across multiple governments, the Finnish position has been that joining NATO has not been necessary and it has been preferable to retain an independent defence policy, but, if conditions change, the country may still exercise the option to join NATO.<ref>{{cite news |url = https://www.hs.fi/kuukausiliite/art-2000008551871.html |title = Optio, jonka arvo vain nousee |author=Unto Hämäläinen |date = 5 February 2022 |accessdate = 22 March 2022 |language = fi |work = [[Helsingin Sanomat]]}}</ref> Removing barriers to effectively exercising the option to join an alliance (for example, by increasing interopability) is a part of this policy.{{sfn|MoFA|2022|p=14}}

The possibility of Finland's membership in NATO was one of the most important issues debated in relation to the [[2006 Finnish presidential election|Finnish presidential election of 2006]], and continues to be a significant issue in Finnish politics.<ref name=sauli /> In 2007, Finland made various technical preparations for membership, with the then Defence Minister [[Jyri Häkämies]] eager to pursue NATO membership.<ref>{{cite news |url=http://euobserver.com/9/23948 |work=EUobserver |title=Finland waits for new EU treaty before NATO membership review |first=Andrew |last=Rettman |date=26 April 2007 |access-date=20 September 2008}}</ref> Public interest in the issue decreased in subsequent years.

Finnish think tank {{ill|Elinkeinoelämän valtuuskunta|lt=EVA|fi|Elinkeinoelämän valtuuskunta}}, which has regularly commissioned opinion polls on NATO membership, noted in its 2015 report a downward trend in the percent opposed that started in 1998, including a steep decline after the [[2012 Finnish presidential election|2012 presidential election]].<ref>{{cite news |url=http://www.eva.fi/blog/2015/02/03/evan-arvo-ja-asennetutkimuksen-ennakkotieto-nato-kannat-muuttuneet-myonteisemmiksi/ |title=MEVAn Arvo- ja asennetutkimuksen ennakkotieto: Nato-kannat muuttuneet myönteisemmiksi |date=3 February 2015 |access-date=11 February 2015 |work=Elinkeinoelämän valtuuskunta |language=fi}}</ref> In March 2014, during [[Annexation of Crimea by the Russian Federation|Russia's annexation of Crimea]], one survey showed only 22 percent supported membership, though a second showed that 53 percent would support membership if Finnish leadership recommended it.<ref>{{cite news |title=Verkkouutiset selvitti: Kansa valmis Natoon, jos valtiojohto niin haluaa |url=http://www.verkkouutiset.fi/kotimaa/nato%20galluppi%20julki%20ti-17919 |date=25 March 2014 |work=Verkkouutiset |first=Satu |last=Schauman |access-date=1 September 2014 |language=fi}}</ref> Support for a military alliance with neighbor [[Sweden]] was also high, at 54 percent,<ref>{{cite news |url=http://www.defensenews.com/article/20140326/DEFREG01/303260045/Majority-Finns-Support-Swedish-Military-Alliance |archive-url=https://wayback.archive-it.org/all/20140328160313/http://www.defensenews.com/article/20140326/DEFREG01/303260045/Majority-Finns-Support-Swedish-Military-Alliance |url-status=dead |archive-date=28 March 2014 |title=Majority of Finns Support Swedish Military Alliance |work=Defense News |date=26 March 2014 |access-date=27 March 2014 |first=Gerard |last=O'Dwyer}}</ref> and Finland could possibly seek an enlarged role for [[NORDEFCO]].<ref name=DW>{{cite news|last=Steffen|first=Sarah|title=NATO next for Sweden and Finland?|url=http://www.dw.de/nato-next-for-sweden-and-finland/a-17519846|newspaper=DeutscheWelle|date=26 March 2014}}</ref> [[Minister of Defence (Finland)|Finnish Minister of Defence]] Carl Haglund suggested that a referendum on NATO membership could be held sometime after the [[2015 Finnish parliamentary election|2015 parliamentary election]].<ref>{{cite news |url=https://www.reuters.com/article/us-finland-nato-defenceminister-idUSKBN0ET1V320140618 |title=Finnish reasons for joining NATO 'stronger than ever': defense minister |first1=Sakari |last1=Suoninen |first2=Jussi |last2=Rosendahl |date=18 June 2014 |access-date=18 June 2014 |work=Reuters}}</ref>

=== Political positions ===

Prior to the [[2022 Russian invasion of Ukraine]], the [[National Coalition Party]] and [[Swedish People's Party of Finland]] supported NATO membership, and the other parties were neutral or opposed to varying degrees. In 2016, the party conference of the National Coalition Party agreed that Finland should apply for membership "in the next few years".<ref>{{cite news |url=http://www.verkkouutiset.fi/politiikka/kokoomuksen%20kannanotot-51679 |title=Kokoomus päätti Nato-linjastaan: Puolustusliittoon lähivuosina |date=12 June 2016 |access-date=12 June 2016 |publisher=Verkkouutiset}}</ref> In the vision of the Swedish People's Party of Finland set out in the same year, Finland will be a NATO member in 2025.<ref>{{cite news |url=http://yle.fi/uutiset/rkp_on_nyt_virallisesti_nato-puolue/8951589 |title=RKP on nyt virallisesti Nato-puolue |date=12 June 2016 |access-date=12 June 2016 |publisher=Yle}}</ref> Many individual politicians have advocated for NATO as well, including the current President [[Sauli Niinistö]] and former Prime Minister [[Alexander Stubb]],<ref>{{cite news |url=https://www.reuters.com/article/us-finland-primeminister-idUSKBN0EP0EW20140614 |title=Stubb to be Finland's next PM, backs NATO membership |first1=Jussi |last1=Rosendahl |first2=Sakari |last2=Suoninen |date=14 June 2014 |access-date=14 June 2014 |work=Reuters}}</ref> as well as former President [[Martti Ahtisaari]],<ref name=sauli/><ref>{{cite news |url=https://www.alaskadispatch.com/article/20140412/ex-president-ahtisaari-calls-finland-join-nato-sweden |title=Ex-President Ahtisaari calls on Finland to join NATO with Sweden |work=Alaska Dispatch |agency=YLE News |date=12 April 2014 |access-date=18 April 2014 |url-status=dead |archive-url=https://web.archive.org/web/20140419031103/https://www.alaskadispatch.com/article/20140412/ex-president-ahtisaari-calls-finland-join-nato-sweden |archive-date=19 April 2014}}</ref> who has argued that Finland should join all the organizations supported by other Western democracies in order "to shrug off once and for all the burden of [[Finlandization]]."<ref>{{cite news|url=http://www2.hs.fi/english/archive/news.asp?id=20031215IE6|title=Former President Ahtisaari: NATO membership would put an end to Finlandisation murmurs|work=Helsingin Sanomat|date=15 December 2003|access-date=20 September 2008|url-status=dead|archive-url=https://web.archive.org/web/20081205075236/http://www2.hs.fi/english/archive/news.asp?id=20031215IE6|archive-date=5 December 2008}}</ref> Two other former presidents from the [[Social Democratic Party of Finland|Social Democratic Party]], [[Tarja Halonen]] and [[Mauno Koivisto]], have publicly opposed the idea, arguing that NATO membership would deteriorate Finland's relations with [[Russia]].<ref>{{cite news|url=http://www2.hs.fi/english/archive/news.asp?id=20040120IE3|title=Finland, NATO, and Russia|work=Helsingin Sanomat|date=20 January 2004|access-date=20 September 2008|first=Max|last=Jakobson|url-status=dead|archive-url=https://web.archive.org/web/20081205075241/http://www2.hs.fi/english/archive/news.asp?id=20040120IE3|archive-date=5 December 2008}}</ref> The [[Left Alliance (Finland)|Left Alliance]] has been the party most opposed to joining NATO; when they entered into coalition with the SDP in 2019, they made clear that any movement towards entering a military alliance would lead to the Left Alliance leaving the cabinet.

=== Polling ===

{{incomplete list |date=April 2022}}

Polls asking the Finnish public whether they support or oppose joining NATO have been regularly conducted. This table includes only unconditional questions; other polled topics include support for joining NATO should Sweden also join, and support for joining NATO if the Finnish government officially recommends membership, both of which generally increased public support for joining.

<!-- NOTICE TO EDITORS: Where sources give extra numerical precision, for consistency in display, round to integer percentages, but calculate the lead from the most precise figures available and also use most precise figures in sort keys. -->

[[File:Sanna Marin and Magdalena Andersson in 2022.jpg|thumb|[[Sanna Marin]] and [[Magdalena Andersson]] talks about potential NATO memberships for Finland and Sweden. In the spring of 2022]]

On 12 May 2022, Finnish President [[Sauli Niinistö]] and Prime Minister [[Sanna Marin]] announced that Finland would begin the process of applying for NATO membership, which they say must be done "without delay". A Finnish application had been anticipated following the [[2022 Russian invasion of Ukraine]] degrading the European security environment, and a significant shift in Finnish public opinion on the desirability of membership.<ref name=Yle20220512>{{Cite web |date=2022-05-12 |title=Finnish leaders confirm support for Nato application |url=https://yle.fi/news/3-12442140 |access-date=2022-05-12 |website=Yle News |language=en}}</ref><ref>{{Cite web |last=Henley |first=Jon |date=2022-05-12 |title=Finland must apply to join Nato without delay, say president and PM |url=https://www.theguardian.com/world/2022/may/12/finland-apply-join-nato-without-delay-president-pm |access-date=2022-05-12 |website=[[The Guardian]] |language=en}}</ref>

The applicant country (i.e., Finland) initiates the accession procedure,{{sfn|MoFA|2022|p=28}} which will be formally started by the government stating the intention to join NATO and producing a specific proposal, which must then be approved in parliament (requiring either a [[majority|simple majority]] or a two-thirds [[supermajority]], to be determined by the {{ill|Committee on Constitutional Affairs (Finland)|fi|Perustuslakivaliokunta|lt=Committee on Constitutional Affairs}}).<ref name=HS20220407>{{ cite news | url = https://www.hs.fi/politiikka/art-2000008725479.html | title = Näin Suomen Nato-päätös etenee – Valtionjohto voi periaatteessa esittää jäsenyyttä milloin tahansa | work = Helsingin Sanomat | date = 7 April 2022 | accessdate = 27 April 2022 | language = fi }}</ref> Such a declaration of intent is expected on 15 May and a proposal will be produced shortly afterwards, which parliament will scrutinise in the following week.<ref name=Yle20220512 /> After taking advice from the government, the [[President of Finland]] will then formally notify NATO of the willingness to begin negotiations.{{sfn|MoFA|2022|p=51}} Negotiations are expected to take weeks, after which Finland would participate in NATO activities at all levels on a provisional basis during the ratification period.<ref name=YleStoltenberg20220505>{{ cite news | url = https://yle.fi/news/3-12432701 | title = Stoltenberg: "Finnish membership will make Nato stronger" | work = Yle News | date = 5 May 2022 | accessdate = 5 May 2022 }}</ref> With negotiations concluded and a reconfirmation of the applicant's intent to join, the accession protocol will need ratification by all the existing NATO member states;{{sfn|MoFA|2022|p=51}} this is estimated to take between four months and a year.<ref name=HS20220420>{{ cite news | url = https://www.hs.fi/politiikka/art-2000008742258.html | title = Eduskunnassa alkaa tänään Nato-keskustelu, joka voi johtaa kauaskantoiseen ja historialliseen päätökseen jäsenyydestä | work = Helsingin Sanomat | date = 20 April 2022 | accessdate = 27 April 2022 | language = fi }}</ref> After ratification is completed, the [[Parliament of Finland]] must pass an [[Act of Parliament|Act]] to formally bring the accession into force.{{sfn|MoFA|2022|p=51}}

During the interval between initiating an application and membership entering into force, Finland would be at risk.{{sfn|MoFA|2022|p=28}} [[Jens Stoltenberg]], [[NATO Secretary General]], said that Finland could join the alliance "very quickly" and that there would be some degree of protection for Finland during that period.<ref name=Yle20220413>{{ cite news |url=https://yle.fi/news/3-12396442 |title=Nato chief: Decision on Finland's membership can be quick |work=Yle News |date=8 April 2022 |accessdate=13 April 2022 }}</ref> ''[[Aftonbladet]]'' reported that, according to American defence sources, this would consist of American and British security guarantees equivalent to full membership,<ref>{{ cite news | url = https://www.bbc.co.uk/news/world-us-canada-61226640 | title = Nato expansion: No set date for Finland application - minister | work = BBC News | date = 26 April 2022 | accessdate = 26 April 2022 }}</ref> and the [[Finnish News Agency]] claimed that non-binding promises would be received from France, Germany, the UK, and the US.<ref>{{ cite news | url = https://yle.fi/news/3-12433294 | title = STT: Germany, France, US pledge military support for Finland during Nato process | work = Yle News | date = 5 May 2022 | accessdate = 5 May 2022 }}</ref>
