How much does Guatemala spend on their military?
According to the Statista website, Guatemala spent approximately 330.4 million U.S. dollars on its military sector in 2021. This was one of the lowest military spending as share of government expenditure in Latin America.
Why is Guatemala with such a small military?
There are several possible reasons why Guatemala has a relatively small military:

Peace agreement: Guatemala went through a long and bloody civil war that lasted from 1960 to 1996. In 1996, a peace agreement was signed between the government and the guerilla forces that ended the conflict. As a result, the need for a large military force decreased.

Economic constraints: Guatemala is a developing country with limited financial resources. As such, the government may choose to allocate its resources to other sectors such as education, healthcare, and infrastructure, rather than military spending.

Regional security: Guatemala is part of the Central American Integration System (SICA), which is a regional organization that aims to promote political, economic, and social integration among its member states. As part of this system, Guatemala may rely on its neighboring countries for mutual security and defense.

International relations: Guatemala maintains good relations with other countries, particularly the United States. As such, it may not feel the need to maintain a large military force to defend itself against potential threats.

Overall, the combination of historical context, economic constraints, regional security arrangements, and international relations may have contributed to Guatemala's decision to maintain a relatively small military force.
