Former NATO Secretary General Jens Stoltenberg says increased European defense spending is critical to securing continued U.S. commitment to the alliance. In an interview with WELT, Stoltenberg noted that more allies are hitting the 3.5% GDP spending target, which serves to address concerns raised by U.S. President Donald Trump regarding burden-sharing ahead of the NATO summit in Ankara.
Why is European defense spending rising toward 3.5% of GDP?
European nations are ramping up military budgets to meet new security demands. Stoltenberg, who currently serves as Norway’s Finance Minister, stated that an increasing number of allies are reaching the target of spending 3.5% of their GDP on core defense tasks.
The push for higher spending responds to direct pressure from Washington. Stoltenberg acknowledged that Donald Trump’s demands for a redistribution of costs within the alliance are “right.” He suggested that increased investment is the most effective way for Europe to maintain the transatlantic bond and ensure U.S. engagement remains steady, even under different political administrations.
How does European security protect the United States?
Stoltenberg argues that the defense of the U.S. begins at the European-Russian border. He rejects the idea that European security is a separate issue from American safety, framing the continent as a frontline buffer.

Norway serves as a primary example of this strategic importance. The country shares a land border with Russia and plays a central role in monitoring Russian submarine movements. By maintaining these capabilities, European allies provide a layer of security that directly impacts the stability of the United States.
Despite these shared goals, Stoltenberg admitted there are “serious disagreements” between NATO partners. He cited ongoing disputes, such as the disagreement over Greenland, as evidence of internal friction that the alliance must navigate.
What is the strategy for supporting Ukraine?
The former NATO chief is calling for “maximum support” for Ukraine to ensure the country remains an independent, democratic nation. He believes that the level of aid provided now will dictate the eventual outcome of the conflict.
According to Stoltenberg, the Russian invasion has been a “strategic failure” for Moscow. He noted that while Russia is paying a massive price for the war, Vladimir Putin has failed to achieve any of his primary strategic objectives.
Stoltenberg does not believe that diplomatic efforts will change Putin’s mind. Instead, the goal of increased military and economic support is to change the Kremlin’s “calculation” regarding the cost of continuing the war.
