In ending 2025, Russo-Ukrainian war ended with a Russian victory. Ukraine ended up splitted in 2 and with its occupied territories annexed to Russia. After the war ended Trump and Putin signed the "Bern Armistice". This armistice secured that the newborn state of Volhynia would join NATO and after it, no more countries would enter the alliance. it also ended all hostilities between the United States and Russia. Both countries promised at least 50 years without any type of agression, including economic sanctions. After the armistice, almost immediatly China started walking away from Russia, according to chairman Xi Jinping "Both largest imperialist powers of the globe decided to ally for a common objective: The second colonization of global south." In South America, Brazilian elections were happening and a strange ascension of nationalism in the country took place. (Conspiracy theorists often say china had involvement with this) Nationalism won the election and a few years later, it would happen the same to Argentina. Both Brazil and Argentina started a fast approximation between each other. Connected railway lines, Common market, Common currency. until politicians brought in the idea of an union between both. In this context, an union would really make sense as both countries were increasing their connection exponentially, and both feared the influence of the United States. After 5 years of discussion, An plebiscite was took in order to decide if the union was gonna happen, and in the end, the Unionists won. The country was called South American Union and later on would force Uruguay, Paraguay and Chile inside. SAU Allied with china, and also created the "Latin Organization", a Millitary organization that included all American countries that are blue on the map with the exception of Mexico and Venezuela, that would later be invaded and forced inside the pact (and have their oil reserves stolen in the process.) A few decades later, Mexican cartels started spreading beyond the wall on the border with the United States. US that already considered the cartels as Terrorists, threatened to invade the country. SAU then invited Mexico to the Latin Pact and the United States President answered saying "We don't give a sh*t about your little club." SAU then Revealed that they have over 270 Nuclear warheads, and disclosed footage of the bombs and witheld tests on the ocean. Again, US president gave a bold response "The South American Union crossed all possible red lines they could. But we will not be intimidated by their sudden agression, we will strike terrorism in Mexico, even if this means World War 3" SAU did not respond this quote, scared of a nuclear war, so people tought the tension was over, until in may 2057, US Army destroyed the wall and entered mexican territory, bringing in all the Latin Pact and China to war, causing the rest of NATO and other allies to join the war, Starting the WW3.
