Finland to join NATO on Tuesday 

Finland will formally become a full-fledged NATO ally on Tuesday, the alliance’s Secretary-General Jens Stoltenberg said Monday. 

“This is an historic week,” the NATO chief told reporters. “Tomorrow, we will welcome Finland as the 31st member of NATO, making Finland safer and our alliance stronger.” 

A ceremony marking Finland’s accession is set to take place Tuesday afternoon. 

“We will raise the Finnish flag for the first time here at the NATO headquarters,” Stoltenberg said, adding: “It will be a good day for Finland’s security, for Nordic security, and for NATO as a whole.”

The move comes after Hungary and Turkey ratified Finland’s membership bid last week, removing the last hurdles to Helsinki’s accession. 

Sweden’s membership aspiration, however, remains in limbo as Budapest and Ankara continue to withhold support. 

Speaking ahead of a meeting of NATO foreign ministers, Stoltenberg reiterated that he believes Stockholm is still on its way to ultimately joining the alliance as well. 

“All allies,” he said, “agree that Sweden’s accession should be completed quickly.”

At their meeting on Tuesday and Wednesday, ministers will discuss the alliance’s defense spending goals and future relationship with Kyiv. 

They will also attend a session of the NATO-Ukraine Commission together with Ukrainian Foreign Minister Dmytro Kuleba and meet with partners from ​Australia, Japan, New Zealand and South Korea.

In his press conference, the NATO chief also addressed multiple challenges facing the transatlantic alliance, including Russian President Vladimir Putin’s recent announcement that Russia will deploy tactical nuclear weapons to Belarus. 

Putin’s announcement is “part of a pattern of dangerous, reckless nuclear rhetoric” and an effort to use nuclear weapons as “intimidation, coercion to stop NATO allies and partners from supporting Ukraine.”

“We will not be intimidated,” the NATO boss said.

The alliance “remains vigilant, we monitor very closely what Russia does,” he said. “But so far,” he added, “we haven’t seen any changes in their nuclear posture” that require any change in NATO’s nuclear stance.

In a statement Monday, the Finnish president’s office said that, “Finland will deposit its instrument of accession to the North Atlantic Treaty with the U.S. State Department in Brussels on Tuesday” before the start of NATO foreign ministers’ session. 

Sanna Marin, the prime minister when Finland applied to join NATO, suffered defeat in a national election on Sunday. Her Social Democrats finished third, with the center-right National Coalition Party coming out on top.
