NATO leaders are scheduled to convene in Ankara on July 7–8, 2026, amid intensifying skepticism over the United States' readiness to defend Europe against potential Russian aggression. While European anxieties have surfaced periodically in the past, the current level of political uncertainty regarding Washington’s commitment appears uniquely acute in the context of the present geopolitical crisis.
Experts, including those from Northeastern University, believe these European concerns are well-founded, even if Russia is unlikely to seek a direct military conflict with Britain, France, or Germany. Furthermore, after two years of intensive combat in Ukraine, Moscow lacks sufficient forces to launch a full-scale offensive against NATO. Nevertheless, Europe remains vulnerable: its defense systems require modernization, and the deployment of heavy weaponry will take years.
The Ankara summit agenda is centered on three key priorities: accelerating the growth of defense spending, boosting the industrial capacity of the defense sector, and providing long-term support for Ukraine. NATO Secretary General Mark Rutte aims to transform a backlog of promises into concrete results and investments.
A historic turning point occurred at the June 2025 Hague summit, where every NATO member except Spain pledged to increase defense spending to 5% of GDP by 2035. This target more than doubles the previous 2% benchmark established in 2014. In 2025, European nations and Canada had already boosted defense expenditures by 20%—an increase of $139 billion in nominal terms. Germany has taken the boldest steps; in March 2025, the Bundestag approved a landmark constitutional amendment, enabling the government to allocate €1 trillion in national debt toward defense and infrastructure. Under Chancellor Friedrich Hertz’s plan, Berlin’s military budget is projected to reach €162 billion by 2029—surpassing the combined spending of France and the United Kingdom.
Europe is undergoing a fundamental reorientation toward conventional military power, investing not only in combat systems and manpower but also in strategic infrastructure, energy independence, and cybersecurity. This pivot is driven in part by the vulnerability exposed by reliance on Russian energy imports and the perceived need to reduce strategic dependence on the U.S. in critical scenarios.
Analysts and Eastern European leaders warn that if the U.S. scales back or ends its NATO involvement, Ukraine risks falling under Russian control. At the same time, European heads of state maintain a sense of "cautious optimism" as they seek reaffirmation of the sanctity of Article 5 (the collective defense clause), though the volatility of American politics leaves little room for certainty.
Behind the official vows of an "ironclad commitment" to collective defense lies a deeper question: is this a fundamental redistribution of responsibility within the alliance, a genuine strengthening of NATO’s European pillar, or merely a temporary lull before another round of transatlantic friction? The answer will largely define the future architecture of Euro-Atlantic security.
