Military forces are often considered essential to national sovereignty and security, yet over 20 countries have chosen not to maintain standing armies.
These nations rely on historical treaties, foreign protection, and international diplomacy, shaped by their unique historical contexts and geographic conditions.
This absence of a military allows countries to redirect defence funds toward social services, education, healthcare, and infrastructure, fostering internal stability and reducing the likelihood of conflicts.
However, they depend on external forces for defence, creating vulnerabilities if alliances shift or partners face conflicts, and they must rely on diplomacy and international law to deter potential aggressors.

According to demilitarisation, Here are 25 countries that have no military forces
Andorra: Nestled between France and Spain, Andorra has no standing military. Instead, defence responsibilities are shared between France and Spain as part of longstanding treaties.
Cook Islands: As a self-governing territory in free association with New Zealand, the Cook Islands relies on New Zealand for defence matters, should the need arise.
Costa Rica: Perhaps the most famous of these nations, Costa Rica abolished its military in 1948 after a civil war. The funds that would have been spent on defence were instead allocated to education and healthcare, turning the country into a bastion of peace and democracy in Central America.

Grenada: Similar to Dominica, Grenada’s defence is managed through regional cooperation within the OECS, along with assistance from the United Kingdom.
Haiti: Following years of military coups and instability, Haiti disbanded its military in 1995. The country now relies on its National Police Force for internal security, with support from international peacekeepers when necessary.
Iceland: One of the most developed countries without a standing army, Iceland relies on its membership in NATO and a bilateral defence agreement with the United States for security.
Kiribati: This Pacific Island nation has no military and depends on Australia and New Zealand for its defence needs.
