As the United States deepens its involvement in Ukraine by allowing military contractors to maintain and repair weapons, it is a timely reminder of how crucial military backing can be for nations under threat.
While most nations maintain armed forces for national defense, several countries have chosen not to maintain a standing army, navy, or air force.
These countries rely on international agreements, regional partnerships, or police and security services for their protection and internal order.
Below are examples of countries that do not have any military forces, along with explanations of how they handle defense and security..
1. Costa Rica
Costa Rica has no military since 1948 when it was constitutionally abolished after a civil war and the government chose to invest in education and healthcare instead relying on a national police force and specialized units for internal security and disaster response while international defense and military agreements are handled through diplomacy and international partnerships.
2. Iceland
Iceland has no standing army but maintains a coast guard and civilian crisis response units relying on its NATO membership and a defense agreement with the United States for military protection while focusing on diplomatic neutrality and internal security through police and special units
3. Liechtenstein
Liechtenstein abolished its military in 1868 due to high costs and since then has had no armed forces relying on Switzerland for diplomatic protection and maintaining only a small national police force for internal affairs
4. Panama
