Finland joins NATO amid Ukraine war

Finland is poised to join NATO on Tuesday, a historic realignment brought on by Russia’s invasion of Ukraine, but the head of the military alliance said it would not send more troops to the Nordic country unless it asked for help.

Russia has already warned that it would bolster defenses along its border with NATO if the alliance deploys any additional troops or equipment to its new member.

“There will be no NATO troops in Finland without the consent of Finland,” NATO Secretary-General Jens Stoltenberg told reporters at NATO headquarters in Brussels a few hours before the country joins.

But he refused to rule out the possibility of holding more military exercises there and said that NATO would not allow Russia’s demands to dictate the organization’s decisions.

“We are constantly assessing our posture, our presence. We have more exercises, we have more presence, also in the Nordic area,” he said.

Later Tuesday, Finland is set to officially become the 31st member of NATO and take its place among the ranks of the world’s biggest security alliance.

Alarmed by Russia’s invasion of Ukraine last year, Finland applied to join NATO in May, setting aside years of military non-alignment to seek protection under the organization’s security umbrella. Neighboring Sweden also applied, but its accession process may take a few months longer.

Finland shares a 1,340 kilometer (832 mile) border with Russia, so its entry will more than double the size of NATO’s border with Russia. The move is a strategic and political blow to President Vladimir Putin, who has long complained about NATO’s expansion toward Russia.

Russia’s Deputy Foreign Minister Alexander Grushko said Monday that Moscow would respond by bolstering its defenses if needed.

“We will strengthen our military potential in the west and in the northwest,” Grushko said, according to state RIA Novosti news agency. “In case of deployment of forces of other NATO members on the territory of Finland, we will take addition steps to ensure Russia’s military security.”

Stoltenberg said that once it joins, Finland will benefit from NATO’s “iron-clad security guarantee,” under which all member countries vow to come to the defense of any ally that comes under attack.

“By (Finland) become a full-fledged member, we are removing the room for miscalculation in Moscow about NATO’s readiness to protect Finland, and that makes Finland safer and stronger, and all of us safer,” Stoltenberg said.

Finland’s entry, to be marked with a flag-raising ceremony at NATO headquarters, falls on the organization’s very own birthday, the 74th anniversary of the signing of its founding Washington Treaty on April 4, 1949. It also coincides with a meeting of the alliance’s foreign ministers.

Finland’s president, foreign and defense ministers will take part in the ceremony.

Türkiye became the last NATO member country to ratify Finland’s membership protocol on Thursday. It will hand over the document officially enshrining that decision to U.S. Secretary of State Antony Blinken before the ceremony.
