WASHINGTON — As the Russian invasion of Ukraine continues with no end in sight, NATO’s much-celebrated unity faces fresh strains when leaders gather for their annual summit this week in Vilnius, Lithuania.
The world’s biggest security alliance is struggling to reach an agreement on admitting Sweden as its 32nd member. Military spending by member nations still lags behind longstanding goals. And an inability to compromise over who should serve as NATO’s next leader forced an extension of the current secretary general’s term for an extra year.
Perhaps most thorny are questions over how Ukraine should be eased into the alliance. Some maintain admitting Ukraine to NATO would be the fulfillment of a promise made years ago and a necessary step to deter Russian aggression in Eastern Europe. Others are fearful it would be seen as a provocation that could spiral into an even wider conflict.
Bickering among friends is not uncommon, and the current catalogue of disputes pales in comparison to past fears that Donald Trump would turn his back on the alliance during his presidency. However, the challenges come at a moment when President Joe Biden and his counterparts are heavily invested in demonstrating harmony among members.
“Any fissure, any lack of solidarity provides an opportunity for those who would oppose the alliance,” said Douglas Lute, who served as U.S. ambassador to NATO under President Barack Obama.
Russian President Vladimir Putin is eager to exploit divisions as he struggles to gain ground in Ukraine and faces political challenges at home, including the aftermath of a brief revolt by the Wagner mercenary group.
“You don’t want to present any openings,” Lute said. “You don’t want to present any gaps or seams.”
By some measures, the Ukraine conflict has reinvigorated NATO, which was created at the beginning of the Cold War as a bulwark against Moscow. Members of the alliance have poured military hardware into Ukraine to help with its ongoing counteroffensive, and Finland ended a history of nonalignment to become NATO’s 31st member.
“I think it’s appropriate to look at all the success,” Senate Minority Leader Mitch McConnell, a Kentucky Republican, said in an interview with The Associated Press. “So I think the invasion has strengthened NATO — exactly the opposite of what Putin anticipated.”
He noted Germany’s shift toward a more robust defense policy as well as other countries’ increase in military spending.
The U.S. announced Friday it will provide Ukraine with the controversial cluster munitions. Such a bomb poses a higher risk of civilian harm as it opens in the air releasing smaller “bomblets” across a wide area, hitting multiple targets simultaneously. Ukraine has promised to use it carefully.
In a statement on Saturday evening, Italian Premier Giorgia Meloni — one of Western Europe’s staunchest backers of Ukraine in the war — reiterated her country’s condemnation of the Russian aggression but called for the “universal application of the principles” of the international convention banning the production, transfer, and stockpiling of cluster munitions.
But the ongoing war has allowed other challenges to fester or bubble to the surface.
In particular, NATO leaders said back in 2008 that Ukraine would eventually become a member, but little action has been taken toward that goal. Putin occupied parts of the country in 2014 and then attempted to capture Kyiv in 2022, leading to the current war.
“A gray zone is a green light for Putin,” said Daniel Fried, a former U.S. ambassador to Poland, and now a distinguished fellow at the Atlantic Council.
The U.S. and Germany insist that the focus should be on supplying weapons and ammunition to help Ukraine win the current conflict, rather than taking the more provocative step of extending a formal invitation to join NATO.
However, countries on NATO’s Eastern flank — Estonia, Latvia, Lithuania and Poland — want firmer assurances on future membership.
Ukrainian President Volodymyr Zelenskyy is pushing for that as well. During a visit to Prague on Thursday, he said the “ideal” result of the Vilnius summit would be an invitation for his country to join the alliance.
Jake Sullivan, Biden’s national security adviser, described the summit as “an important moment on that pathway toward membership” and that allies need to “discuss the reforms that are still necessary for Ukraine to come up to NATO standards.”
NATO could use the occasion to elevate its relationship with Ukraine, creating what would be known as the NATO-Ukraine Council and giving Kyiv a seat at the table for consultations.
Also in the spotlight in Vilnius will be Turkish President Recep Tayyip Erdogan, the main obstacle blocking Sweden’s attempts to join NATO alongside its neighbor Finland.
Erdogan accuses Sweden of being too lenient on anti-Islamic demonstrations and militant Kurdish groups that have waged a decades-long insurgency in Turkey.
Sweden recently changed its anti-terrorism legislation and lifted an arms embargo on Turkey. However, a man burned a Quran outside a mosque in Stockholm last week, and Erdogan signaled that this would pose another obstacle. He equated “those who permitted the crime” to those who perpetrated it.
Turkey and the U.S. are also at an impasse over the sale of F-16 fighter jets. Erdogan wants the upgraded planes, but Biden says that Sweden’s NATO membership has to be dealt with first.
Sullivan said the U.S. is confident that Sweden will join NATO “in the not-too-distant future,” but it’s unclear if the matter will be resolved during the summit.
It’s not the first time that Erdogan has used a NATO summit for Turkish gain. In 2009, he held up the nomination of Anders Fogh Rasmussen as secretary general but agreed to the move after securing some senior posts for Turkish officials at the alliance.
Max Bergmann, a former State Department official who leads the Europe Program at the Center for Strategic and International Studies, said there’s growing frustration among allies toward Erdogan, building on concerns about his ties to Putin, democratic backsliding and sanctions evasion.
“They’ve tried playing nice,” Bergmann said. “The question is whether it’s time to get much more confrontational.”
Hungarian Prime Minister Vitkor Orban is also delaying his country’s approval of Sweden’s membership. In response, Sen. Jim Risch, the top Republican on the Senate Foreign Relations Committee, is blocking a $735 million U.S. arms sale to Hungary.
“We don’t want members who aren’t interested in doing everything possible to strengthen the alliance rather than the pursuit of their own or individual interests,” he said. “I’m just sick and tired of it.”
However, Risch rejected the idea that these disagreements are a sign of weakness within NATO.
“These are kinds of things that always arise in an alliance,” he said. “The fact that we’ve been able to deal with them and will continue to deal with them proves that this is the most successful and strongest military alliance in the history of the world.”
At least one potentially flammable item has been taken off the summit agenda. Rather than seek consensus on a new NATO leader, members agreed to extend Jens Stoltenberg’s tenure for a year. He’s had the job since 2014, and it’s the fourth time that his time in office has been extended.
Most wanted a woman to take the top job next, and Danish Prime Minister Mette Frederiksen had been considered a favorite candidate. However, Poland insisted that a candidate from the Baltic states should be next because there had already been two Nordic secretaries general in a row. (Stoltenberg was a Norwegian prime minister, and Rasmussen was a Danish prime minister.)
Others are skeptical of accepting a nominee from the Baltics, whose leaders tend to be more provocative in their approach to Russia, including supporting Ukraine’s desire to rapidly join NATO.
More disagreements loom over NATO’s updated plans for countering any invasion that Russia might launch on allied territory. It’s the biggest revision since the Cold War, and Skip Davis, a former NATO official who is now a senior fellow at the Center for European Policy Analysis, said it could involve “lots of arm wrestling and card trading.”
“That’s an issue that will cause tension and dissent, and that’s not what the Vilnius summit is all about,” he said.
