Most countries around the world have an army to protect their borders and maintain security. However, there are a few nations that have chosen not to keep a standing military. Instead, they rely on other methods like police forces, defence agreements with other countries, and peaceful foreign policies to ensure safety for their people and stability within their borders.
Why Some Countries Choose not to Have an Army?
The absence of a military in these nations often comes down to a mix of factors:
- Historical Decisions – Some disbanded their armies after wars or political changes to focus on peace and development (e.g., Costa Rica, Panama).
- Small Size & Location – Many are tiny island nations or microstates that rely on bigger allies for protection (e.g., Monaco, Palau).
- Economic Priorities – Maintaining an army is costly, so funds are directed toward health, education, and infrastructure.
- Peace Treaties & Neutrality – Some have agreements with neighboring countries to stay neutral and avoid military conflicts.
