Is NATO a force of good in the world?

Whether the North Atlantic Treaty Organization (NATO) is a "force for good" is a subject of significant international debate. Since its founding in 1949, opinions on its role have depended heavily on a nation's geopolitical position, historical experiences, and political philosophy.

Arguments that NATO is a Force for Good

Proponents of NATO—primarily its member states, democratic allies, and liberal internationalist scholars—view the alliance as a cornerstone of global stability and peace. Their key arguments include:

•Deterrence of Major War: Supporters argue that NATO's core principle, Article 5 (collective defense: "an attack on one is an attack on all"), has successfully prevented a major war between great powers in Europe for more than 75 years. By establishing a highly credible deterrent, NATO has created a secure environment that allows European democracies and economies to thrive.

•Defense of Democratic Values: NATO's founding treaty commits members to democracy, individual liberty, and the rule of law. Proponents point out that the prospect of NATO membership has historically served as a powerful incentive for candidate nations, particularly in Central and Eastern Europe after the Cold War, to implement democratic reforms, establish civilian control over their militaries, and resolve ethnic disputes peacefully.

•Protection Against Authoritarian Aggression: In the wake of Russia’s invasion of Ukraine, supporters argue that NATO is more vital than ever. They contend that without the alliance's security umbrella, neighboring democratic nations—such as the Baltic states—would be highly vulnerable to territorial aggression and coercive expansion.

•Crisis Management and Humanitarian Interventions: Proponents highlight NATO’s role in ending ethnic violence and restoring peace in the Western Balkans during the 1990s, as well as its efforts in counter-piracy, disaster relief, and counter-terrorism (such as the deployment in Afghanistan after the 9/11 attacks, which was the only time Article 5 was invoked).

Arguments that NATO is Not a Force for Good

Critics of NATO—including realist foreign policy scholars, anti-war advocates, and rival powers like Russia and China—argue that the alliance's actions have often undermined global security. Their primary arguments include:

•Provocation and the "Security Dilemma": Prominent critics, including some Western foreign policy realists, argue that NATO's eastward expansion after the collapse of the Soviet Union unnecessarily provoked Russia. They contend that pushing a powerful military alliance to Russia's borders created a "security dilemma," fostering deep distrust and ultimately contributing to the geopolitical instability that sparked conflicts in Georgia (2008) and Ukraine.

•Overreach and Violations of Sovereignty: Critics point to NATO military interventions that occurred outside of its defensive territory ("out-of-area" operations). A frequent example is the 1999 bombing of Yugoslavia, which was conducted without UN Security Council authorization. Others point to the 2011 intervention in Libya, which critics argue went beyond protecting civilians and led to long-term state collapse, factional warfare, and humanitarian crises.

•A Tool for U.S. Hegemony: Some argue that NATO is primarily an instrument for projecting American military power and maintaining a unipolar global order. From this perspective, the alliance draws European nations into U.S.-led global conflicts and prioritizes highly militarized, confrontational foreign policy over diplomatic solutions.

•Internal Inconsistencies: Skeptics point out that NATO has often overlooked democratic backsliding or human rights abuses among its own members (both historically, such as during periods of military rule in Greece and Turkey, and more recently with concerns over domestic policies in some member states). This leads to accusations that NATO's claim of being an alliance of "shared democratic values" is applied selectively.

Conclusion

To its supporters, NATO is an indispensable shield of collective security, deterrence, and democratic solidarity that has successfully preserved the peace in Europe for generations. To its critics, it is a Cold War relic whose expansion has destabilized international relations, fueled militarism, and led to destabilizing military interventions outside its borders. Ultimately, whether NATO is viewed as a force for good depends on how one weighs the value of its deterrence against the geopolitical friction its existence and expansion have generated.
