Is NATO a force of good in the world?

Is NATO a force for good? I'll examine its record, missions, and the competing perspectives to assess the question.

Whether NATO is a "force for good" is a normative question with different answers depending on perspective and criteria. Here is how the debate is generally framed:

What NATO is

NATO - the North Atlantic Treaty Organization - was formed in 1949 by 12 countries to provide collective defense against the Soviet Union during the Cold War.

Its core principle is collective defense, enshrined in Article 5 of the NATO Treaty, which holds that an attack against one member state is considered an attack against all members. Article 5 has been invoked only once in NATO's history - after the 9/11 terrorist attacks against the United States in 2001, formally confirmed on October 2, 2001 after evidence showed the attacks had been directed by al-Qaeda from Afghanistan.

Supporters, including U.S. officials, have described it as among the most successful alliances in world history and as “the greatest combined force for good in world history, defending our freedom and democracy around the globe”. NATO's former SACEUR argued: “I believe this all reflects a NATO alliance that is a force for good in the world... our collective efforts help create security and bring some measure of stability in a dangerous world”.

Arguments that NATO is a force for good

1. Deterrence and prevention of war in Europe:
For over 75 years, no NATO member has been attacked by another major power, which supporters credit to deterrence. The collective defense guarantee made NATO threats look much more serious and coordinated and helped deter Soviet aggression because an attack on one counted as an attack on all. After Russia illegally annexed Crimea in 2014, the Alliance shifted back to its original deterrence and collective defence mission enshrined in Article 5.

2. Crisis management and peacekeeping after the Cold War:
After the Cold War ended, NATO took on new roles like crisis management and peacekeeping. It has expanded from a regional collective defense organization to a collective security organization having global aspirations.

Examples often cited:

•In both Bosnia in 1995 and Kosovo in 1999 NATO redefined its mission from protecting its members to deploying troops in nonmember countries as peacekeeping forces. In both cases NATO succeeded in preventing any more clashes between warring parties.
•NATO deployed its first ever peace-support operation to Bosnia and Herzegovina in 1995 and later intervened to end the crisis in Kosovo in 1999, playing a key role in stabilising the Western Balkans.
•The Kosovo Force (KFOR) presence significantly contributed to the reduction of violence, protection of civilian populations, and facilitation of the return of refugees in Kosovo.
•Today, NATO is involved in peacekeeping operations in Kosovo, Operation Sea Guardian in the Mediterranean and maritime security missions protecting freedom of navigation and combatting illegal human trafficking, supporting humanitarian disaster relief, and counter terrorism operations.

3. Upholding a rules-based order and democracy:
Supporters argue NATO creates stability, which has been good for the United States both economically and politically, and that its partnership network strengthens security worldwide.

This view is reflected in public opinion in member states. Recent U.S. polling finds 73 percent of Americans believe that keeping the United States in NATO matters to America’s security and prosperity, and seven out of ten Americans (71%) strongly or somewhat support NATO.

Arguments that NATO is not, or is not always, a force for good

Critics - including governments such as Russia and China, and some peace and left-wing groups in the West - make several criticisms:

1. Not purely defensive:
Russian Foreign Minister Sergei Lavrov has claimed NATO’s history in Yugoslavia, Libya, and Afghanistan proves it is not purely a defensive alliance, also pointing to operations against Belgrade without UN Security Council approval, as well as in Iraq, Libya and Afghanistan.

2. Controversial interventions:

•Libya (2011): Critics say NATO misused a UN Security Council resolution to fight a war for regime change. The intervention is linked by critics to subsequent instability and the emergence of militant groups.
•Afghanistan (2003-2021): NATO involved itself in a war far from Alliance territory, only to hand power, 20 years later, to the Taliban — whose overthrow had been the invasion's stated objective. That war was marked by numerous war crimes — such as the October 2015 U.S. airstrike on a Doctors Without Borders hospital in Kunduz — which went unpunished.
•More broadly, critics describe a Pandora’s box of illegal wars on Afghanistan, Libya, Iraq and Syria, with a bloody trail of destruction, forced removal, sorrow, and death.

3. Expansion and escalation:
Critics describe post-Cold War NATO expansionism and military interventionism as pursuit of unipolarity / collective hegemony. They argue that the NATO-backed regime change in Ukraine aimed at transforming the country from a Russian partner into a frontline state aligned against Russia triggered the war in 2014. Others view NATO as defensive in name but offensive in nature and structured to be aggressive.

Even more sympathetic assessments note that NATO’s interventions in Afghanistan and Libya faced criticism for a lack of coordination and potential economic conflicts of interest.

Bottom line

•If "good" is defined as preventing interstate war among members, deterring Soviet/Russian aggression, ending ethnic cleansing in the Balkans in the 1990s, and providing a stable security framework that enabled European economic and political integration, the evidence supports the view that NATO has been a net positive - which is why it retains majority public support in the U.S. and Europe.
•If "good" is defined as strict adherence to international law, non-intervention, avoiding civilian casualties, and not provoking adversarial powers, critics argue NATO has at times acted beyond its defensive mandate and contributed to instability.

Most scholars therefore describe NATO as effective at collective defense but controversial in its out-of-area crisis interventions, with its legacy as a "force for good" depending heavily on which cases and values are prioritized.
