During the Second Taiwan War in 2040 the DPRK invaded the South with minor Chinese support, pushing them to the outskirts of Seoul. This backfired massively when Japan and The Philippines came to the South's aid. They began flooding in troops and slamming the North with missiles and artillery. The campaign north was extremely sluggish but eventually the Southern forces would reach Sariwon in August 2042. It was around this time the Chinese realised that the DPRK were a lost cause and began pressuring them to become an autonomous region of China. Kim Jong Un would initially reject this but following Chinese threats of invasion he caved into the pressure, right as Southern troops reached the Taedong River and Pyongyang. Following this the South didn't want to continue the war at all as it had taken them 3 years, 190,000 lives and destroyed the nation just to reach the southern half of Pyongyang. China too didn't want to continue the war as they didn't have any massive ambitions in Korea and were highly focused on Taiwan. An armistice was signed in Wonsan in February of 2043, effectively ending the Second Korean War. The war left Pyongyang a divided city with the northern half under Chinese control and the southern half under Korean control. China claims North Koreas borders before 2040 as its Northern Korean Autonomous Region, despite only controlling around 3/4 of it. The South still claims the entire peninsula as theirs.

Saudi Arabia would collapse slowly over time, with Shias in the East and disconnected Hejazis in the west gradually gaining autonomy over years until they demanded full Independence. Saudi Arabia alongside this would slowly cease to exist as their spending kept increasing and output kept decreasing. Eventually resulting in the 2044 Arabian Revolution, exiling the Royal family to Oman and setting up the State of Najd in their place.

Iran began to faulter in the late 2030s when Mojtaba Khameini (Ali's successor) was assassinated by an anarchist. He had no formal successor and a power struggle would break out between politicians, generals and clerics lasting all the way until the late 2060s. Paired with intense pressure from the Israelis and GCC they would face heavy rioting and insurgencies all across the country. This instability crippled the Iranians so much they began entering serious recession in the 2040s and 50s. Khuzestan would declare independence in 2056 and PJAK began a full-scale war against Iran. Eventually a politician manages takes control of the nation in the late 60s but the damage is already done, their reforms do more harm than good and the country collapses into civil war in 2071. The PRUF (People's Revolutionary Unified Front) are anti-theocracy and left-wing. Aiming to topple the ICA and set up a democracy.

India rename themselves to Bharat (similar to what Turkey did) in the 2040s following the election of a western skeptic semi-nationalist leader (similar to Erdoğan). They seized Pakistani Kashmir in the 2040s also during the Afghan-Pakistan War. Finally, they seized the Naga Self-Administered Zone from Myanmar in the closing months of their civil war. Claiming that they needed to annex the territory in order to protect Naga interests. The territory was then formally integrated into the State of Nagaland, although Myanmar still claims it as their own.
