This comprehensive analysis analyzes the fundamental differences between NATO member countries and non-NATO nations across three critical dimensions.
With NATO’s recent historic decision to increase defense and security spending targets to 5% of GDP by 2035, the alliance showcases an unprecedented commitment to collective security. In 2024, NATO countries collectively spent $1.47 trillion on defense, with an average of 2.71% of GDP compared to the previous target of 2%.
According to the International Institute for Strategic Studies (IISS), global defence spending in 2024 rose to US$2.46 trillion, from US$2.24 trillion in 2023.
NATO is a 32-member country alliance for political and military purposes. Established in 1949, the oldest member countries include Belgium, the United States, Canada, Denmark, France, Iceland, Italy, Luxembourg, the Netherlands, Norway, Portugal, and the United Kingdom. Finland and Sweden recently became NATO countries in 2023 and 2024, respectively.
This article compares the fundamental differences between NATO vs non-NATO nations across three critical dimensions – Defense, Economy, and Technology.
Defense and Security Analysis
NATO Defense Spending 2024
– Total Spending – $1.47T
– Average Spending of GDP – 2.71%
– Members Meeting 2% – 23
– Spending to Spend of GDP – 5%
Defence Expenditure of NATO Members
In terms of spending on defense as a share of GDP, Poland (4.12%) is leading the allies, followed by Estonia (3.43%), the U.S. (3.38%), Latvia (3.15%), and Greece (3.08%).
Defense Spending of Key Non-NATO Countries
Several non-NATO nations have significantly increased their defense budgets and play influential roles in global defense and security. Leading the list of non-NATO countries’ defense spending is China, with $249 billion.
| Non-NATO Countries | Defense Expenditure (2025) | Increase from 2024 |
| China | $249 billion | 7.2% |

| Japan | $70 billion | 9.4% |
- Israel’s military expenditure surged by 65 per cent to $46.5 billion in 2024.
Economic Performance and Trade
NATO countries collectively represent a significant portion of the global economy. As of 2024, they accounted for 30.4% of global GDP, with $64,255.2 billion. NATO’s share of global GDP growth stands at 20.3% during 2014-2024, and the 10-year Compound Annual Growth Rate (CAGR) is 2.3%.
The average military spending for all NATO members in 2024 stands at 2.2 per cent of GDP, equivalent to approximately US$1.5 trillion.
NATO vs Non-NATO – Economic Advantages
When we compare the Foreign Direct Investment (FDI) of NATO vs non-NATO member countries, there are higher inflows in NATO members due to stability, while non-NATO countries are variable and risk-dependent. When we talk about Trade Facilitation, there are streamlined processes between NATO members, whereas non-NATO countries focus on individual negotiations.
Technology and Innovation Ecosystem
The technology and innovation ecosystem of NATO is a critical focus, especially in the context of emerging and disruptive technologies (EDTs) and the evolving security landscape. Since its inception, the North Atlantic Treaty Organization (NATO) has been at the forefront of technology to ensure the defense of its member countries and the success of its operations.
At the 2021 Brussels Summit, NATO leaders agreed to establish a NATO Innovation Fund. The EUR 1 billion venture capital fund provides strategic investments in start-ups developing dual-use emerging and disruptive technologies in areas that are critical to Allied security.
The leaders at the summit agreed to launch the Defence Innovation Accelerator for the North Atlantic (DIANA) to promote transatlantic cooperation on critical technologies, foster interoperability, and harness civilian innovation by engaging with academia and the private sector.
NATO currently focuses its innovation activities on nine priority technology areas:
- Artificial Intelligence (AI)
- Autonomous Systems
- Quantum Technologies
- Biotechnology and Human Enhancement Technologies
- Space
- Hypersonic Systems
- Novel Materials and Manufacturing
- Energy and Propulsion
- Next-generation Communications Networks
NATO is actively developing and implementing initiatives and programs to foster a robust technology and innovation ecosystem.
The Final Thought
NATO was born from the Cold War’s strategic imperative and remains a cornerstone of collective defense. The group shares measurable security benefits among each other that also create economic advantages through reduced risk premiums and increased foreign investment.
Conversely, countries outside NATO, or non-NATO nations, are increasingly asserting their influence globally. Economies, such as the BRICS nations, represent a growing force in international trade and have capitalized on globalization to build competitive industries and consumer markets.
The future of global security depends on the ability of adaptation and collaboration opportunities of both NATO and non-NATO countries. Despite the global benefits and challenges, it will be exciting to see what the future holds for the world.
