What are the next steps for Finland and Sweden on NATO membership?

Finland and Sweden have signalled their intention to join NATO over Russia's war in Ukraine, and things will move fast once they formally apply for membership in the world's biggest security alliance.

Russian President Vladimir Putin has made clear that there would be consequences if the two Nordic countries join. Sothe nations' leaders feel it's important for NATO to bring them swiftly into the fold so they can benefit from the security guarantees that membership provides.

They're off to a quick start. Finland and Sweden are NATO's closest partners. They have functioning democracies, well-funded armed forces and already contribute to the alliance's military operations and air policing. Any obstacles they face will merely be of a technical, or possibly political nature.

How long will it take?

NATO officials say the membership procedure could be completed "in a couple of weeks."

Yet the most time-consuming part ratification of their accession protocols by the alliance's 30 member countries, sometimes involving parliaments could take months. How many is anyone's guess. With recent candidates,that step has taken eight to 12 months.

The fastest entrants were West Germany, Turkey and Greece, whose endorsements took around four months in the 1950s, when NATO was less than half its current size. Still, a war on NATO's doorstep is sure to focus minds.

Mlanie Joly, Canada's minister of foreign affairs, spoke Monday in Brussels ahead of a meeting with the European Union's top diplomat,Josep Borrell. Joly said Canada is in favour of a "quick accession"for both countries.

"Our goal is to be among the first countries to be able to ratify the accession of Sweden and Finland," she said.

The U.S. and Britain, among others, stand ready to provide security support if needed until the process is complete.

How does a country join?

NATO's membership process isn't formalized, and the steps can vary.

First, though, a request to join must be submitted. It usually comes in the form of a letter from a government minister or leader.

NATO then assesses that request. That's done in a sitting of the North Atlantic Council (NAC) of the 30 member countries, probably at the ambassadorial level.

The NAC decides whether to move toward membership and what steps must be taken to achieve it. This depends on how well aligned the candidate countries are with NATO's political, military and legal standards, and whether they contribute to security in the North Atlantic area. Thisshould pose no problem for Finland and Sweden.

Finland, Sweden in NATO not an existential threat to Russia, says analyst

Finland and Sweden joining NATO is destabilizing for Russia but not the existential threat that would be posed if a country from the former Soviet space joined the alliance, says Andrew Rasiulis, a Fellow from the Canadian Global Affairs Institute.

How do membership talks work?

If the NAC gives a green light, accession talks are held. These are likely to be completed in just one day. The steps are fairly straightforward.

The candidate is asked to commit to uphold Article 5, NATO's collective defence clause guaranteeing that an attack on any one ally would be met with a response from them all. It would have to commit to spending obligations concerning the NATO in-house budget, which runs to around $2.5 billion US.

The candidate is made aware of their role in NATO defence planning, and of any other legal or security obligations they might have, like the vetting of personnel and handling of classified information.

NATO staff then write a report informing allies about the outcome of the talks. The report states what issues were raised with the partner and what commitments that country made. At the same time, the candidate sends a letter, usually from a foreign minister, confirming that their country accepts all these obligations.

How does a country know if it's accepted?

The accession report and candidate's letter are submitted once more to the NAC for a final decision.

The council which can meet at the level of ambassadors, ministers or leaders then reviews the application, and decides whether to sign the accession protocol with the candidate.

If yes, a small ceremony is held giving a symbolic and legal form to this part of the membership process. The protocol is then sent to capitals for ratification according to the 30 national procedures, some of which require parliamentary approval.

Once completed, the invitee then ratifies the protocol and deposits it in Washington. They are then officially a member and their national flag is hoisted outside NATO headquarters in Brussels.

Are there any objections to them joining?

NATO takes all its decisions by consensus, so each country has a de facto veto.

Last week, Turkish President Recep Tayyip Erdogan raised concerns about Finlandand Swedenjoining NATO, citing their stance on Kurdish militants, whom Turkey classifies as terrorists.

Erdogan didn't threaten outright to veto membership, and officials and analysts believe he won't stand in their way. No other country has raised serious objections to Finland and Sweden joining, either in public at home or at NATO headquarters in Brussels, officials say.
