NATO leaders began a two-day summit in Ankara, Turkey, on Tuesday to discuss defense spending and regional security threats [1].

The meeting arrives as the United States increases pressure on European allies to share the financial burden of collective defense. With geopolitical tensions rising, the alliance must reconcile differing views on funding and resource allocation to maintain a credible deterrent against global adversaries.

U.S. President Donald Trump is attending the summit, which runs through Wednesday, July 8 [1], [3]. A primary focus of the discussions is the progress toward a target of spending five percent of GDP on defense by 2035 [2]. This figure represents a significant increase over previous guidelines, reflecting a push for higher readiness across the bloc.

Beyond financial targets, the leaders are addressing critical gaps in military hardware. NATO Secretary General Mark Rutte highlighted the fragility of current stockpiles during the proceedings. "Allies don’t have an endless supply of missile interceptors," Rutte said [6].

The agenda also includes coordination on regional conflicts and strategic interests. Leaders are discussing the ongoing conflict involving Iran, and managing interests in Greenland [4], [5]. These discussions aim to synchronize the alliance's response to threats that extend beyond the traditional European theater.

Throughout the summit, the U.S. is expected to emphasize the need for allies to secure their own borders and reduce reliance on American military assets [5]. The outcome of these meetings will likely determine the trajectory of transatlantic security cooperation for the next decade.

"Allies don’t have an endless supply of missile interceptors."

The shift toward a 5% GDP spending target signals a fundamental transition in NATO's economic model, moving away from the long-standing 2% benchmark. By focusing on missile-interceptor shortages and Arctic interests, the alliance is attempting to modernize its hardware and geographic scope to match contemporary threats, while the U.S. continues to push for a more equitable distribution of costs.
