The Mexico-USA War was a conflict between Mexico and the USA that began on April 12, 2011. It was one of the major fronts in the ONE-led invasion of the USA and part of the much larger World War V.

The war was a result of Mexico signing a Mutual protection pact with Poland during the USA-Poland War, and included a brief two-phase invasion of the USA homeland.

The war was concluded on May 20, 2011 with a peace treaty signed by both nations and Mexico conceding defeat.^[1]

Background

Months before the war the country of Mexico had been conquered by the USA during the Second USA-Mexico War in December of 2010. Mexico would afterwards be allowed to reemerge as a sovereign nation and relationships between the USA and Mexico would begin to stabilize before the outbreak World War V.

However, in the weeks leading up to World War V, Poland would also wipe Mexico from the map; eventually securing most of the lower-east territories, particularly the rubber region of Southeast of Mexico and possibly threatening an invasion of North of Brazil. In response, the USA would assist Mexico, going so far as to open up its own territories for refugees and designating Oklahoma as a temporary reservation from which Mexico would then be able to reconquer most of it northern territories with the exclusion of Baja, which the USA (as part of the arrangement) wanted to keep for its saltpeter resource.

Prior to direct conflict between both nations the USA had attacked Polish held territories in occupied Mexico during the early stages of the USA-Poland War as an attempt to relieve the pressure that France was experiencing during the ONE invasion of France.

After the USA was unsuccessful in ousting Poland from Mexico during the USA-Poland War, Mexico signed a Mutual protection pact with Poland and proceeded to resistance war Baja back to its original ownership. The Mexico-Poland agreement was believed to be due to threats issued by Poland against Mexico, declaring that if Mexico did not assist Poland, the former country would be conquered by Polish forces and a potential PTO would be initiated. Mexico felt the Polish threat was significant enough to persuade them to align themselves with ONE.

For some time afterwards Mexico provided a buffer-zone between the USA and Poland, forcing both nations to pursue attacks through territories and MPPs in Europe. Eventually Poland would attack, and secure, the USA territory of Delaware and shortly thereafter Spain would enter North America during the USA-Spain War.

In response, Canada would come to the aid of the USA by agreeing to a series of territorial swaps in an effort to prevent rapid encroachment by ONE forces.

Mexico took this as an opportunity to solidify its relationship with ONE member-states and accordingly launched its own attack into the USA mainland.

April 14, 2011 - Mexico and Spain advance into the USA.

Initially Mexico made swift headway against the USA, securing a number of easily won battles and pushing through the USA South and Mid-West states until it finally managed to link Mexican occupied territories with those that had also been conquered by Spain. The two forces would temporarily link up at the Mississippi River on April 14, 2011 and momentarily cut the USA in half.

However, in the following days the USA would launch a series of successful Resistance Wars and quickly decimate Mexican advances into their territories. Following this, the USA would attack the Mexican homeland, once again focusing first on the resource rich territory of Baja.

After some border fighting Mexico would launch another offensive into the USA by occupying Arizona on April 23, 2011. They would push on to Nevada the following day, but would be beaten back by US forces.

The US would then liberate its territories and once again occupy Baja, thereafter beginning its own campaign in the border conflict by attacking the Northeast of Mexico. This would represent the first time the USA entered into Mexican territory during the war, with the exclusion of Baja, which had previously been under sustained US annexation since the Second USA-Mexico War.

Eventually the USA was able to continue placing pressure upon Mexico, eventually all but wiping the country. The last remaining Mexican territory was Oaxaca. Since Poland had been removed from the Americas, and the USA-Spain War had reduced Spanish holdings to the remaining hold-out of Indiana, the Mexican position began to shift towards one of peace.

On May 20, 2011, both countries agreed to terms and an official peace treaty was signed, bringing the war to an end.
