Why do Finland and Sweden want to join NATO?

Swedish Prime Minister Magdalena Andersson and Finnish Prime Minister Sanna Marin have both spoken out about their wish for their countries to join NATO.

Ms Marin said that the situation in Ukraine had “changed everything” and that Finland should be “prepared for all kinds of actions from Russia”.

She said: “The difference between being a partner and a member is very clear, and will remain so. There is no other way to have security guarantees than under Nato’s deterrence and common defence as guaranteed by the alliance’s article five.”

Both countries are keen to join due to the threat of Russia and the ongoing conflict in Ukraine.

During a joint press conference between the two nations, Ms Andersson added: “There is a before and after 24 February.

“This is a very important time in history. The security landscape has completely changed. We have to analyse the situation to see what is best for Sweden’s security, for the Swedish people, in this new situation.”

Polling in Finland and Sweden now shows that public opinion supports joining the group.

On 11 May, during a join press conference with UK Prime Minister Boris Johnson, Finnish President Sauli Niinistö said that his country would make Russia aware of their impact on their NATO deliberations, saying: “If [retaliation] would be the case then my response would be: you caused this. Look in the mirror.”

When will Finland and Sweden be given membership to NATO?

By 16 May, both Sweden and Finland had given their official confirmation that they will be submitting their application to the group.

Ms Andersson said: “There is a broad majority in Sweden’s parliament for Sweden to join NATO.

“This is the best thing for the security of Sweden and its people. We will inform NATO that we want to become a member of the alliance.”

Both nations confirmed that they were submitting applications simultaneously, with Finnish President Sauli Niinistö adding: “A protected Finland is being born as part of a stable, strong and responsible Nordic region. We gain security, and we also share it. It’s good to keep in mind that security isn’t a zero-sum game.”

NATO secretary general Jens Stoltenberg has said that the journey from applicant to member for Finland and Sweden would be “smooth and swift”.

The US is among those to have backed both nations joining the defensive alliance.

Finaldn and Sweden have both voiced fears over Russian retaliation during a “gray period” between applying and being granted membership.

The application of any country to NATO must be approved by all 30 members of the group.

Countries often wait four months to one year until their membership is confirmed after first applying and are only granted Article 5 collective secuirty assurances once full membership is given.

However, the US has said that it is “ready to provide various forms of security assurances” during this period of the application, according to Swedish Foreign Minister Ann Linde following a meeting with US Secretary of State Antony Blinken, due to the looming threat of Russia on the Nordic bloc.

Boris Johnson has also pledged the UK’s assistance to both Sweden and Finland against any Russian threats.

What has Russia said about Finland and Sweden joining NATO?

Russia has continued to warn that any expansion of NATO would be seen by the Kremlin as hostile.

Kremlin spokesman Dmitry Peskov previously said that the group “remains a tool geared towards confrontation” and warned it could destabilise European security.

It was previously critical of the alliance’s planned expansion eastwards into Ukraine, with Russia stating this as a major reason in troops being placed along the border and eventually invading the country.

The Kremlin may be specifically worried about Finland in particular joining NATO, as it shares a 830 mile long border with the country.

Russian president Vladimir Putin has said that the country is not worried about the inital expansion saying: “As to enlargement, Russia has no problem with these states - none. And so in this sense there is no immediate threat to Russia from an expansion to include these countries.”

However, he did give a veiled threat if NATO weapons were to be placed in Finland and Sweden after membership has been granted, saying that it “would certainly provoke our response”.

He added: “What that will be - we will see what threats are created for us.”
