Finland’s NATO membership triggered by Putin’s invasion of Ukraine

HELSINKI/BRUSSELS (Reuters) – Finland will become a member of NATO on Tuesday, completing a historic security policy shift which alliance chief Jens Stoltenberg said was triggered directly by Russian President Vladimir Putin’s invasion of Ukraine.

“President Putin had as a declared goal of the invasion of Ukraine to get less NATO,” he told reporters at NATO’s Brussels headquarters, speaking hours before Finland was officially to become a member.

“He is getting exactly the opposite… Finland today, and soon also Sweden will become a full fledged member of the alliance,” Stoltenberg said.

The Kremlin said that Russia would be forced to take “counter-measures” to Finland’s accession, as Defence Minister Sergei Shoigu said the move raised the prospect of the conflict in Ukraine escalating further.

Kremlin spokesman Dmitry Peskov said the expansion of NATO – long criticised in Moscow – was an “encroachment on our security and on Russia’s national interests” and that Moscow would watch closely for any NATO military deployments in Finland.

The military alliance will welcome Finland as its 31st member in a flag-raising ceremony at NATO headquarters on the outskirts of Brussels, attended by Finnish President Sauli Niinisto and government ministers.

The event marks the end of an era of military non-alignment for Finland that began after the country repelled an invasion attempt by the Soviet Union during World War Two and opted to try to maintain friendly relations with neighbouring Russia.

But Russia’s invasion of another neighbour, Ukraine, which began in February 2022, prompted Finns to seek security under the umbrella of NATO’s collective defence pact, which states that an attack on one member is an attack on all.

Sweden underwent a similar transformation in defence thinking and Stockholm and Helsinki applied together last year to join NATO. But Sweden’s application has been held up by NATO members Turkey and Hungary.

After both those countries approved Finland’s application last week, the final formal step on Helsinki’s journey will come when Foreign Minister Pekka Haavisto hands his nation’s accession document to U.S. government officials in Brussels.

Finland’s flag will then be raised outside NATO headquarters alongside those of the alliance’s 30 other member countries before a gathering of NATO foreign ministers.

RUSSIAN BORDER

Finland’s accession roughly doubles the length of the border that NATO shares with Russia. Moscow said on Monday it would strengthen its military capacity in its western and northwestern regions in response to Finland joining NATO.

Even before Finland formally joined the alliance, its armed forces have been drawing closer to NATO and its members.

NATO’s surveillance flights by the U.S. and other allied air forces have already began to circulate in Finnish airspace, the Finnish defence forces said.

On March 24, air force commanders from Sweden, Norway, Finland and Denmark said they had signed a letter of intent to create a unified Nordic air defence aimed at countering the rising threat from Russia.

“We would like to see if we can integrate our airspace surveillance more, so we can use radar data from each other’s surveillance systems and use them collectively,” Major General Jan Dam, commander of the Danish air force, told Reuters.

Finns said on Monday said they were pleased the NATO membership process would soon be complete, even if some harboured reservations.

“I feel maybe a little conflicted about joining NATO because I’m not the biggest fan of NATO but at the same time even less a fan of Russia,” said Henri Laukkanen, a 28-year-old financial assistant.

Finland and Sweden had said they wanted to join NATO “hand in hand” to maximise their mutual security but that plan fell apart as Turkey refused to move ahead with Stockholm’s bid.

Turkey says Stockholm harbours members of what Ankara considers terrorist groups – a charge Sweden denies – and has demanded their extradition as a step toward ratifying Swedish membership.

Hungary is also holding up Sweden’s admission, citing grievances over criticism of Prime Minister Viktor Orban’s democratic record.

But NATO diplomats say they expect Budapest to approve Sweden’s bid if it sees Turkey moving to do so. They hope Turkey will move after presidential and parliamentary elections in May.
