Is NATO a force of good in the world?

Is NATO a force for good? I'll examine its record, achievements and criticisms to give you a balanced answer.

Whether NATO is a "force for good" is debated and depends on how its record is weighed. Arguments are made on both sides:

The case that NATO is a force for good

Original purpose and core function:
NATO, or the North Atlantic Treaty Organization, was established in 1949. Its primary purpose was to provide collective security against the Soviet Union. It was founded in the aftermath of World War II, with the purpose of securing peace and security in Europe.

Its fundamental goal is to safeguard the Allies' freedom and security by political and military means, and it remains the principal security instrument of the transatlantic community and expression of its common democratic values.

Today, NATO protects more than 1 billion people in Europe and North America from 21st-century threats.

Collective defense and deterrence:
The treaty's key provision was Article 5, which began: "The Parties agree that an armed attack against one or more of them in Europe or North America shall be considered an attack against them all". This is the principle of collective defense.

For more than five decades, the primary function of Article 5 was deterrence. Its success was measured by the lack of a conventional war in Europe. The lack of breaches to NATO members' sovereignty should be interpreted as a success of the Alliance's policy of deterrence.

Article 5 has been invoked only once in the organization's history, following the 9/11 attacks, which is often cited as evidence of successful deterrence - while Article 5 remains a symbol of unity and deterrence, its infrequent use reflects the alliance's success in preventing major conflicts within its member states.

Peacekeeping and crisis management:
Since the end of the Cold War, NATO shifted its focus from solely deterring Soviet aggression to promoting broader stability and taking on new missions including peacekeeping and crisis management in the Balkans.

Examples frequently cited:

•NATO took the lead in stopping two conflicts in the Balkans, in Bosnia and Kosovo, and in creating peacekeeping forces that have helped chart a path away from age-old grievances
•KFOR's presence significantly contributed to the reduction of violence, protection of civilian populations, and facilitation of the return of refugees in Kosovo
•The North Atlantic Treaty Organization has been involved in active peacekeeping missions since 1994, and coordinates with United Nations peacekeeping operations
•The collective defence ... through partnerships ... is carried out by a leading role in peacekeeping and crisis response operations. By contributing to peace and security, NATO helps to create political stability and economic growth
•The Alliance has supported the African Union (AU) in peacekeeping efforts, providing logistics, training, and other forms of assistance
•It has been engaged in counterpiracy operations off the coast of Somalia

In UK parliamentary debate, supporters have described using voice through organisations such as NATO, to be a force for good in this world, and supporters often describe NATO as a tremendous force for good in the world.

Public opinion in the US reflects this positive view: 77% say being a member of NATO is good for the U.S., while 15% say bad.

Criticisms and concerns

Critics argue that NATO's actions sometimes mirror those of an unchecked military power, where strategic objectives overshadow humanitarian concerns, particularly in the Balkans, Afghanistan, and Libya.

Assessments of NATO interventions often vary by case. One Brookings-linked analysis suggests that if success of crisis resolution shifted from very positive (Kosovo) to neutral (Libya) and ultimately to negative (contemporary Afghanistan).

•Kosovo (1999): Generally seen as the most successful, but still controversial. Critics have called NATO's operation over Kosovo illegitimate, and some argue the intervention as a new norm of intervention has backfired by exacerbating violence.
•Afghanistan (2001-2021): NATO led the International Security Assistance Force. Critics list that NATO's operation in Afghanistan was a failure.
•Libya (2011): The Libyan intervention eventually led to regime change and ... now a failed state. Others note Libya has not only failed to evolve into a democracy; it has devolved into a failed state. NATO's operation over Libya was described by critics as illegitimate.

Expansion and relations with Russia:
Despite its benefits, NATO has faced criticism that NATO's expansion eastward after the end of the Cold War has contributed to tensions with Russia.

Key arguments against expansion include the concern that it will exacerbate tensions with Russia; result in substantial costs and risks; and dilute the mission, political likemindedness, and military effectiveness of the alliance.

Some analysts present the post-Cold War expansion to Russia's borders, without seriously considering Russia's inclusion, as a "tragic mistake". Others argue the opposite - that there was never a formal promise to keep NATO from expanding and that Russia feared expansion largely because the alliance represented a check on its extraterritorial ambitions.

Other criticisms argue NATO's mission has become too expansive, and that it has engaged in military interventions beyond its original mandate, and that it is first and foremost a military alliance, not primarily a bulwark of liberal values.

Bottom line

•To supporters, NATO's 75+ year record of preventing an attack on any member state, ending wars in the Balkans, and upholding a rules-based, democratic alliance makes it a net force for stability and good.
•To critics, its out-of-area wars, civilian casualties, the outcomes in Libya and Afghanistan, and its role in escalating great-power tensions undermine that claim.

Most scholarly and policy assessments land in between: NATO has been highly effective at its core task of collective deterrence, and relatively effective at short-term peacekeeping, but with mixed to negative long-term results in nation-building and intervention - and with legitimate debate about whether its expansion and global role promote or undermine long-term security.
