Former NATO Secretary General Jens Stoltenberg warns that European nations must increase defense spending to secure continued United States involvement in the transatlantic alliance. Speaking to WELT ahead of the NATO summit in Ankara, Stoltenberg argued that higher investment is the primary way to maintain American engagement, particularly as political shifts in Washington create uncertainty regarding long-term U.S. commitments to Europe.
How can Europe secure U.S. commitment to NATO?
The most effective way for Europe to maintain the transatlantic bond is through increased financial investment in defense. Stoltenberg, who currently serves as Norway’s Finance Minister, told WELT that while he agrees with Donald Trump’s demand for a redistribution of the alliance’s financial burden, the responsibility lies with European partners.

According to Stoltenberg, more allies are now meeting the target of spending 3.5 percent of their GDP on core defense tasks. He noted that this upward trend in spending is essential to ensuring that the United States remains deeply invested in European security, regardless of which administration holds power in Washington.
If the United States were to withdraw from the alliance in the future, Stoltenberg suggested that Europe would need to rely on its own independent defense capabilities. This shift toward “Europeanized” defense remains a significant long-term trend for the continent’s strategic planning.
Why does European security directly impact American safety?
Stoltenberg argued that the defense of the United States begins at the European-Russian border. He emphasized that the security of the American homeland is inextricably linked to the stability of the European frontier.
Norway serves as a primary example of this strategic link. The country shares a land border with Russia and performs a critical role in monitoring the movement of Russian submarines. This regional surveillance provides a layer of security that benefits the entire North Atlantic alliance, including the U.S.
Despite “serious disagreements” between NATO partners—such as ongoing disputes regarding Grönland—Stoltenberg expressed confidence that the alliance can remain a strong transatlantic force. He maintains that the interests of the United States are best served by a robust and well-funded European defense architecture.
What is the recommended approach for the war in Ukraine?
To achieve a lasting peace, Stoltenberg called for “maximal support” for Ukraine during the upcoming NATO summit. He stated that the more support provided to Kyiv, the more likely the war is to end with Ukraine remaining an independent, democratic nation within Europe.
Stoltenberg characterized the full-scale invasion of Ukraine as a “strategic failure” for Moscow. He noted that while Russia is paying a significant price, President Vladimir Putin has failed to achieve any of his primary strategic objectives.
The former NATO chief suggested that the goal of Western intervention should not be to change Putin’s mind through persuasion, but to change his calculations through strength. By mobilizing maximal support, the alliance aims to ensure Ukraine holds a powerful position before any potential negotiations occur.
