Its been quite a huge update in terms of what has happened since the war took a strange turn. The forces of the Populists and the communists began to deteriorate as despite their initially large advances against the Entente-MittelEuropa front, the two groups had many ideological, territorial and personal disputes which eventually led to them going to war with each other, despite the distractions they had from the other powers. This allowed the powers in which they were fighting to take advantage of the combat and make more out of this, while the civil war in America started to both escalate further as several groups began to look towards the development of atomic bombs to give them an advantage over one another. Not only did this happen, but several powers had previously been neutral entered on behalf of the anti-socialist coalition. These included the Japanese Empire, China (having recently crushed the Tang rebellion once and for all), Arabia and even the Spanish State and Italian royal government. Due to the vast power the socialists had, even against each other, it was admittedly almost impossible to truly remove the groups from power the way the Axis were destroyed in our timeline, and so the allied governments instead settled with conditional peace of varying levels of harshness, thus hoping that the remaining Populist and Communist regimes would face dissidence and collapse on themselves. This certainly worked with Italy, who was quickly reunited under the royal government, though the royals are still reluctant on having to cede a portion of land to Switzerland.
Additionally, the Ulanbataar pact was destroyed by the Nationalists and Japanese. Afterwards, the Japanese reluctantly ceded control of Manchuria over to the nationalists, allowing them to reunite China, though they are nevertheless somewhat disappointed on not being able to have Formosa back. Japan also managed to occupy parts of the Russian Far East for a lease of 50 years. The Russian Popular Union also had to grant independence to Turkmenistan and cede territory to Finland, Ukraine, Transcaucasia and China, as well as withdrawing military from the Black Sea. The Eco-Agrarian Syndicate was another casualty of the war, despite not being a member of the Popular Front, which allowed the peoples of Brazil to make effort into reconstructing their country, though the millions that were lost in the catastrophic regime and then the civil war require the country to take a vast amount of time to recover. While not as bad in its civil war, the US has been forced to lose several territories like California, Texas and Alaska, and barely managed to hold onto Hawaii. What was the worst in this was the nuclear devastation, as over 8 nuclear weapons were used in the last part of the civil war in 1947. The only populist regime that managed to blossom out of this was the Free Congo Commune, which currently is trying to mend the damage caused by the Belgian royal government and improve the rights of its people, taking a more democratic leaning in governance.
The communist block has arguably suffered even more from the war, likely due to its overall increased extremism and more militarised threat. Of course Italy's communists were utterly destroyed, as were the communist uprisings in South America, while the nations of Turan and Spain were devastated to the point of being almost discredited. The previously near Stalinist regime in Turan lost all its Arab and Kurdish territory, as well as it's remaining Armenian and Greek territories, also being required to demilitarise and reduce its military forces to below 50,000 overall. This led to the establishment of a major government opposition, as the previously very powerful government were utterly powerless to stop rebellions. A similar situation was rising in the Iberian peninsula, where almost all of the independence groups were given their own lands such as Aragon, Euskadi, Galicia, Asturias and Cantabria. The Spanish State made advances in the south west as well, but due to its incompetence was unable to gain much else. In order to cope with these economic disasters, they have recently been trying to implement reforms in their society. It is now 1949, and a new era begins.
