The transformation witnessed in the global security architecture in recent years clearly demonstrates that NATO has evolved beyond being merely a military alliance into an increasingly influential geopolitical and geo-economic actor. One of the clearest indicators of this transformation is the changing trajectory and composition of defense expenditures.
The target introduced at the 2014 Wales summit, which established defense spending at 2% of GDP as a benchmark for member states, has effectively become a minimum threshold today. Across NATO, defense expenditure accounted for approximately 2.6% of GDP in 2014, rising to 2.8% by 2024 according to the organization’s annual report. Although this increase may appear numerically limited, particularly given the accelerated budget expansions observed among European countries in recent years, it reflects a broad and sustained horizontal expansion across the alliance.
Escalating geopolitical tensions constitute the primary driver of this trend. Both the Russia-Ukraine war and the broader conflict stemming from the U.S./Israel-Iran war have become central issues on NATO’s strategic agenda, further accelerating defense spending and defense industrial mobilization.
