Why Are So Many Leaders Warning Of War With Russia?

German Defense Minister Boris Pistorius visits Leopard II tanks are due to be supplied to Ukraine in Augustdorf, Germany, February 1, 2023.

Summary

  • NATO chief Mark Rutte and other European leaders have issued repeated warnings in 2025 about a possible Russian attack on NATO countries in the coming years.
  • Some experts doubt Russia’s capability or intent to attack soon, but say Putin may provoke conflict in the longer term to maintain power.
  • A recent think tank report warns Estonia could be targeted, though it estimates Russia would need 5-10 years to rebuild for such an attack.

The polite applause faded and NATO chief Mark Rutte arranged his papers neatly on the rostrum. It took him 62 seconds to get to the point.

“The dark forces of oppression are on the march again,” he said. “We are Russia’s next target.”

Rutte’s speech in Berlin on December 11 was just the latest in an unprecedented series of warnings of direct conflict with Russia made in 2025 by senior European officials and intelligence agencies.

In February, Danish intelligence said “Russia sees itself in conflict with the West and is preparing for a war against NATO;” in June, Germany’s top general said an attack may come within four years; in November, his words were echoed by his Polish counterpart -- two days after German Defense Minister Boris Pistorius said “some military historians even believe we have already had our last summer of peace.”

Rutte: Putin Must Face “Devastating Consequences” If He Tries To Invade Ukraine Again

This list of warnings is far from exhaustive. Rutte has been most frequent.

In January, he urged NATO members to hike defense spending or get Russian language classes, while in June he said an attack could be coordinated with a Chinese assault on Taiwan.

His December 11 speech was his loudest alarm bell yet, speaking of “the scale of war our grandparents or great-grandparents endured” with “mass mobilization, millions displaced.”

What's Behind The Warnings?

The frequent comments have made headlines -- and raised question marks, especially with the United States showing waning interest in maintaining the levels of security support it has given Europe in the past.

“This is something that I’ve been pondering especially as there is no evidence at all that Russia can or wants to attack NATO,” John Foreman, a former British military attache in Moscow and Kyiv, told RFE/RL.

“I think a number of politicians and military types are using the specter of the Russian threat for more prosaic reasons: Rutte to encourage NATO nations to meet their spending commitments. The Poles to get more NATO on their territory,” he added.

Other skeptics have pointed out that after nearly four years of war Russia has been unable to subdue Ukraine -- even if it has been edging forward this year at enormous cost in casualties and equipment.

Teemu Tammikko, from the Finnish Institute of International Affairs, also said that Russia did not appear “willing and able to attack NATO for the moment.”

But he told RFE/RL’s Russian Service that President Vladimir Putin’s grip on power was “dependent on an external threat,” meaning “in the longer term, some kind of direct military provocation is likely, especially if the war in Ukraine freezes.”

Some argue this is already happening, such as with Russian drone and air incursions into NATO airspace. But the warnings issued this year hint at much darker scenarios.

Attack On Estonia

A paper issued by the European Council on Foreign Relations (ECFR) on December 18 focuses on fears of a direct attack on Estonia to test the willingness of the United States and other NATO allies to fight.

“In Europe, this anxiety sits atop a deeper fear: that the American government, distracted by domestic politics and tempted by retrenchment, might soon reduce its presence or attach conditions to its role in Europe’s defense,” it says.

Baltic Countries Worry About Russia After US Pauses Military Aid To Ukraine

Describing Estonia as “small, flat, and exposed,” the report says a 2016 wargame predicted Russian forces could seize the capital within 60 hours of an invasion.

But it also says that Russia would need 5-10 years after the end of the war in Ukraine “to refit and rearm for such an attack” -- a much longer timeframe than those posited by Rutte, Pistorius, and others.

It’s notable that US officials have not repeated European warnings.

The recently released National Security Strategy argues that “European allies enjoy a significant hard power advantage over Russia by almost every measure, save nuclear weapons.”

But it also acknowledges the need for US diplomatic engagement “to mitigate the risk of conflict between Russia and European states.”

'Warmongers'

Kremlin officials have denounced European leaders as “warmongers” and denied any desire to attack. They were making similar comments about Ukraine on the eve of their full-scale invasion in February 2022, though this does not automatically mean there are plans for further aggression.

“Russia is not pursuing the military goals attributed to our country,” Deputy Foreign Minister Sergei Ryabkov said on December 22. “As the President of Russia has already said, we are even prepared to guarantee this legally as part of a settlement” of the war in Ukraine, he added.

But any such commitment would be unlikely to be taken seriously by many in the West. Russia also signed and then broke promises to respect Ukraine’s borders in the 1994 Budapest Memorandum.

Ultimately, it may all depend on one man.

“As we know, Russia is not a democracy. Such a decision would essentially just be a result of Vladimir Putin deciding that he wanted to attack a European country which is a NATO member state, or another European country, so we just have no way of knowing,” Elizabeth Braw, of the RUSI defense and security think tank, told RFE/RL’s Russian Service.

“That's why you see military leaders all over Europe saying we have to be prepared for something to happen tomorrow. It may happen five years, 10 years from now or never, but you can't bank on it.”
