NATO’s northern flank would be more robust if Sweden and Finland join, expert says

A possible NATO membership for Finland and Sweden would be the biggest redrawing of the military map in northernmost Europe since the breakup of the Soviet Union.

No countries are more closely linked to NATO’s security umbrella than Finland and Sweden., with joint exercises, shared intelligence and common political values. But the two Nordic countries are left without the security guarantees that come from Article 5 of the NATO Treaty on collective protection; all for one, one for all.

This week, as an example, Finland and Sweden have fully participated with fighter jets in exercise Ramstein Alloy in the skies over Estonia. The drills included air combat training, air-to-air refueling, and air-policing along the Baltic nation’s eastern border with Russia. In case of war, however, Estonia, unlike Finland and Sweden, will be backed military by NATO.

Russia is now the pushing factor behind what until this winter wasn’t a question on the European security drawing table.

“Everything changed with Russia invaded Ukraine,” Finnish Prime Minister Sanna Marin said when meeting reporters together with her Swedish counterpart, Magdalena Andersson, in Stockholm on Wednesday.

The two spent the day discussing how to strengthen the security of the two countries following the fundamental changes in Europe after Russia’s unprovoked attack on Ukraine.

On Wednesday, Marin’s Government submitted a report to Parliament on how Finland can strengthen its national defence capability and develop military cooperation with partners, the closest of which is Sweden. The report also assesses the effects of a possible move from being a partner nation to becoming a NATO member.

“Security guarantees do not apply to NATO partner nations, only members,” says Per Erik Solli, a senior defense analyst with the Norwegian Institute of International Affairs (NUPI).

Solli told the Barents Observer that Sweden and Finland both are vulnerable today if Russia stages a geographically limited attack similar to the invasion of Ukraine.

“If Finland and Sweden join NATO the risk of attack will decrease and deterrence will be cohesive for the Nordic region,” Solli says.

He underlines that such a move will not only be of importance for the two new members, but also for NATO as such.

“NATO’s northern flank would be more robust if Finland and Sweden become members of the alliance.”

Per Erik Solli notes that Moscow should not fear a united Nordic region in NATO.

“If Finland and Sweden join the alliance there will be no offensive threats or risks to Russia. In the last decade, NATO has evolved back to the core mission of collective defense.”

While Sweden doesn’t border Russia, Finland shares a 1,340-kilometer land border with its eastern neighbor.

Kirkenes closer to Severomorsk 

Former Chief of Finnish Defense Intelligence, now ministerial adviser, Harri Ohra-aho, explains in a tweet that Finland’s direct border with Russia does not in itself increase the risk.

“What matters is what are Russia’s strategic objects beyond the border,” he argues and points to the fact that there are no strategically important sites between the Kola Peninsula and St. Petersburg, except for a couple of military bases.

“Norway’s Kirkenes (NATO) is closer to Severomorsk than Finland’s Ivalo. Estonia’s Narva (NATO) is closer to St. Petersburg than Finland’s Hamina,” Ohra-aho notes.

With Norway being a founding member of the alliance in 1949, the country’s 198-kilometer-long land border to the heavily militarized Kola Peninsula, with some of some of Russia’s most strategically important conventional and nuclear assets, has long had a direct border with NATO. At the same time, the northern land border has also maintained a low-tension assurance between East and West, in sharp contrast to Russia’s other European border regions.

Shortly after the outbreak of the war in Ukraine, NATO’s Secretary-General Jens Stoltenberg announced strengthened cooperation, information sharing and consultations with Finland and Sweden. Last week, Stoltenberg held a bilateral meeting with the two countries’ foreign ministers, Pekka Haavisto and Ann Linde in Brussels.

“We will continue to consult closely,” Ann Linde said after the meeting.

What now happens in Stockholm and Helsinki is a big historical shift for the two countries which have been militarily non-aligned since the end of World War Two.

“Weeks, not months”

In a commentary for the security think tank RUSI, Per Erik Solli and Øystein Solvang explain how the war in Ukraine has profound implications for Nordic security cooperation.

Although the military integration by Finland and Sweden with NATO members Norway, Denmark, and Iceland has evolved gradually over the last three decades, the absence of formal security guarantees creates strategic ambiguity, the two researchers point out.

“This undermines the deterrence effect and the preventive value of this collective defense capability,” Solli and Solvang argue.

Finland and Sweden’s steady march toward NATO membership could happen soon. Quoted by YLE, Prime Minister Sanna Marin said the decision will happen “within weeks not months.”

“Should Finland decide to join NATO while Sweden stays out, the Swedes could easily find themselves in the same isolated position as Ukraine, should the country fall victim to limited Russian aggression,” write the two NUPI researchers Per Erik Solli and Øystein Solvang.

“Only if Finland and Sweden decide to join NATO would the entire Nordic region become part of a comprehensive and robust deterrence scheme to prevent conflict in the High North.”

In 2020, the defense ministers of Norway, Finland and Sweden met at the far northern military base of Porsangermoen and signed an agreement to bolster Nordic security cooperation.

The Nordic power could soon be much stronger than any of the ministers had in mind two years ago.

Medvedev warns 

While Russia largely has itself to thank for getting two more Nordic countries as NATO members, Moscow has this week actively voiced concerns.

Dmitry Medvedev, nowadays deputy chairman of Russia’s Security Council, said such possible NATO membership would be answered with Russia deploying more of its land, naval and air forces in the Baltic Sea region.

The former prime minister and president also waved the nuclear card.

“There can be no more talk of any nuclear-free status for the Baltic, the balance must be restored,” Medvedev said according to Reuters.
