United States invasion of Mexico

The United States invasion of Mexico was a military operation perpetrated against the United Mexican States by the United States of America in order to secure the supply of crude oil from the country. It was the culmination of a year-long campaign of pressure that began with economic sanctions, intended to destabilize the country. The American military ultimately seized the oil refineries and infrastructure, ensuring that it would continue supplying the U.S. with crude oil - at Mexico's expense.
