The Second Mexican-American War, also known as the Patagonia War, the U.S.–Mexican War, the Latin War, and the "War over Nothing," was an armed conflict between the United States and Mexico from 2090 to 2092 in the wake of the 2089 Mexican Annexation of Central America, which the United States considered a direct threat to its interests.

Combat operations lasted for two years, from 2090 to 2092. American forces quickly occupied Panama, then staged a brief incursion into Southern Mexico; meanwhile, Mexican forces, while countering on all fronts, called on their allies in South America to their aid, expanding the War into Argentina, Mexico's most important ally of the war. With American attention split on two fronts, Mexico was able to push American forces back to Panama fighting the Americans to a stalemate by 2092.

The Treaty of Sao Paulo specified the major concessions by both powers to end the war: the United States agreed to recognize Mexican claims to Central America, drawing the Border at Panama, while Mexico recognized American interests in Panama and Ecuadore. Additionally Argentina and Chile were forced to recognize the independence of Machupe and Patagonia, which were little more than American puppet states in the region to counter Mexico's growing influence. The war was officially a stalemate, but most agree that Mexico lost the least and won the most.

The one issue that both sides took great pains to avoid, but was ultimately the driving force behind both their actions, was the Great Deportation and the Southwestern Crisis. Mexico was fiercely opposed to the United State's deportation of millions of Mexicans from the American Southwest (mostly to Mars and the other colonies, though many made their way back to Mexico), while the United States considered Mexico's "Ciudadano Expatriado" policy a direct threat to its sovereignty. Both sides avoided conflict on their mutual border for fear of a larger and bloodier war over which side actually owned the Southwest, but that issue was only forestalled for the Third-Mexican American war in the 2130s.
