Is NATO a force of good in the world?

Whether the North Atlantic Treaty Organization (NATO) is a "force of good" in the world is a complex and deeply polarizing question. For decades, scholars, policymakers, and global citizens have debated the alliance's role.

From the perspective of its member nations and supporters, NATO is an indispensable shield for peace, democracy, and stability. From the perspective of its critics, non-members, and those affected by its military campaigns, it is often viewed as an instrument of Western hegemony that has contributed to global instability and conflict.

Here is an overview of the primary arguments on both sides of the debate.

Arguments That NATO is a Force for Good

Supporters of NATO argue that the alliance has been one of the most successful instruments for peace and stability in modern history. Their arguments center on several key achievements:

•Prevention of Major Conflict in Europe: Founded in 1949 to deter Soviet aggression, NATO’s core principle is Article 5—the collective defense clause stating that an attack on one member is an attack on all. Proponents credit this ironclad guarantee with preventing a major, direct war between European superpowers for over seven decades, fostering an unprecedented era of peace and economic prosperity on the continent.

•Protection of Small Democracies: NATO provides vital security guarantees to smaller, historically vulnerable nations. Following the collapse of the Soviet Union, many Eastern European and Baltic states eagerly sought NATO membership to protect their hard-won independence. In the wake of Russia's invasion of Ukraine, NATO’s role as a deterrent has been reaffirmed, leading long-neutral nations like Finland and Sweden to join the alliance for protection.

•Promotion of Democratic Values: To join NATO, aspiring members must meet strict criteria, including a commitment to democratic governance, the rule of law, individual liberty, and civilian control of the military. Supporters argue this framework incentivized political and military reforms across Eastern Europe in the post-Cold War era.

•Humanitarian Interventions: Proponents point to NATO’s actions in the Balkans during the 1990s—such as in Bosnia and Herzegovina (1995) and Kosovo (1999)—as vital interventions that halted ethnic cleansing and mass atrocities, ultimately paving the way for regional stability.

Criticisms and Arguments Against NATO

Critics, including peace activists, realist foreign policy scholars, and leaders from non-Western nations, argue that NATO’s actions have often undermined global security. Their arguments include:

•Provocative Expansion and Security Dilemmas: Critics argue that NATO’s eastward expansion after the fall of the Soviet Union violated implicit post-Cold War understandings with Moscow and unnecessarily provoked Russia. From this viewpoint, NATO’s growth created a "security dilemma"—whereby defensive steps taken by the West were perceived as offensive threats by Russia—ultimately contributing to the geopolitical tensions that led to the war in Ukraine.

•Controversial and Destructive Interventions: Opponents point to several of NATO's "out-of-area" military campaigns as evidence of its destabilizing impact:

•Yugoslavia (1999): NATO's 78-day bombing campaign was conducted without authorization from the United Nations Security Council, raising severe questions about international law and resulting in civilian casualties.

•Libya (2011): A UN-sanctioned mission to protect civilians quickly evolved into a campaign for regime change that ousted Muammar Gaddafi. Critics argue this intervention left Libya as a fragmented, war-torn failed state, fueling regional terrorism and weapons proliferation.

•Afghanistan: Following the 9/11 attacks (the only time Article 5 has been invoked), NATO led the International Security Assistance Force (ISAF). Critics argue the 20-year war resulted in immense human and financial costs, only to end in the return of the Taliban to power in 2021.

•Instrument of U.S. Hegemony: Some view NATO not as a true multilateral partnership, but as a vehicle for the United States to project its military power globally. They argue it binds European foreign policy to U.S. geopolitical interests, sometimes dragging allies into conflicts that do not serve their own national interests.

•Promotion of Militarism: Critics argue that NATO fosters a highly militarized approach to global problems. Its insistence that member states spend at least 2% of their GDP on defense is seen by some as a diversion of valuable public resources away from education, healthcare, social programs, and climate change mitigation.

Conclusion

Ultimately, whether NATO is viewed as a "force of good" depends heavily on where one sits geographically and politically:

•For those inside the alliance—particularly in Eastern and Northern Europe—NATO is viewed as an indispensable shield that preserves democratic sovereignty and deters existential threats.

•For those outside the alliance, or those who have experienced the fallout of its military interventions, NATO is often seen as an aggressive, Western-centric military bloc that bypasses international law to project power.
