The Union of Socialist Republics of Latin America, better known by its Portuguese/Spanish acronym URSAL, is the largest country of the world, and only third in population and fourth in GDP (though quickly growing). Stretching from the deserts of Sonora to the South Pole, it encompasses a staggering diversity of peoples, enviroments and cultures, joined together in socialist brotherhood.
The origins of the URSAL, ironically, can be traced to a ultra-right wing politician. In late 2018, Cabo Daciolo, a presidential candidate for the Brazilian elections, claimed that there was a conspiracy to form a union of socialist Latin American republics. After a flurry of memes on Brazil and neighboring countries, a majority of people in Brazil and other Latin American nations were overcome by a deep feeling that they best described as "Hey... that actually sounds pretty awesome, why don't we do it?". The presidential elections in Brazil were replaced by a constitutional convention that proclaimed the country as a socialist republic on the path to communism. Similar events happened in other countries, where the people organized and overthrew their corrupt and incompetent governments. In 2019, a general convention of leftists movements and governments proclaimed the URSAL, with the beloved 'Pepe' Mujica as General Secretary. Since then, the new nation has experienced a dramatic growth, aided by widespread social programs and vigorous national industries.
The details of governance of the URSAL are obscure for many political scientists, except that 'It just sorts of works'. Technically, it's composed of Socialist Republics united by a treaty, but as the economies are unified and there are no borders, they seem to be mostly ceremonial. Most administration, both politically and economically happens locally in autonomous republics, provinces, municipalities, tribes, communes, etc. the General Assembly of the URSAL paradoxically exists for only the highest matters
and political theatrics. Pepe Mujica has extense powers as General Secretary, but he mostly uses them to give ocassional speeches and general advice, and rarely leaves his humble farm (the Presidential Rancho) in the outskirts of Montevideo. Membership is still open to nations that are not traditionally Latin-American, proving they know how to live socialistically AND how to party. The URSAL has no nuclear weapons, and only limited military capabilities with a single aircraft carrier, but so far its possible rivals are so dumbfounded by its sudden rise that there are no plans to expand the military at the expense of much needed social reforms.
Of note is that the URSAL is, beyond any doubt, the largest football superpower of the world. While individual national teams still exist*, the URSAL has (retroactively) won 9 world cups, and the URSAL (inter)National Football Team has stars such as Messi, Neymar, Sánchez and Ochoa on its roster, and most of the greatest players in Europe and elsewhere have been born in the URSAL. FIFA has debated just to preemptively hand out the Qatar 2022 cup to them, but they seem eager to compete nevertheless.
*(maybe THAT'S why the countries themselves still exist)
