Mexico has a long history of military involvement, dating back to the early 19th century. The country has participated in various international conflicts and peacekeeping missions throughout its history.
However, it is essential to note that Mexico's war efforts have been shaped by its unique historical context, including the Mexican Revolution and the Cold War.
During World War I, Mexico declared war on Germany and Austria-Hungary in 1917. This decision was largely driven by the country's desire to protect its interests in Central America and the Caribbean.
In contrast, Mexico remained neutral during World War II, despite being a member of the Allied Powers. However, the country did provide humanitarian aid to the Allies and allowed them to use its territory for military operations.
In recent years, Mexico has become increasingly involved in international peacekeeping missions. The country has contributed troops to the United Nations Stabilization Mission in Haiti (MINUSTAH) and the United Nations Organization Stabilization Mission in the Democratic Republic of Congo (MONUSCO).
Mexico has also participated in regional security initiatives, such as the Central American Defense Pact and the Merida Initiative. These efforts aim to promote regional stability and combat organized crime.
