American invasion of Mexico

In 2051, the United States invaded Mexico.

Background
Mexico was under huge pressure from the US to solve its severe political instabilities as well as widespread pollution, which also caused problems in the US. The US saw Mexico's inability to conform to US wishes as a threat to national security, prompting an invasion in order to secure the nation's refineries, as well to ensure that the already scarce resources safely crossed the US-Mexican border. The United States attempted to launch an occupation/annexation operation, but the final decision of this is, as well as the economic and political outcomes of the invasion, unknown.

Appearances
The United States invasion of Mexico is mentioned only in the Fallout Bible.
