Speaking of which, the Indian Ocean:
Despite the loss of their Atlantic Coast, South Africa still managed to stay as Africa's regional power, shortly re-establishing themselves in the Atlantic and went further across to make themselves at the Rio de la Plata Estuary. They also decided to settle the Kalahari Desert to get those sweet sweet diamonds, but Zimbabwe, jealous that it's always the 1st world countries who get the good resources, ended up taking some as well. Meanwhile, Zambia was just motivated on one thing: Copper. Up north, Sudan's large expansion to the Mediterranean was not well received by the reformed Egyptian government in Suez, who didn't want to be in Khartoum's shadow for once.
The rivalry between Saudi Arabia and Iran was reignited by the near loss of the US. While Tehran was expanding their borders, Riyadh was trying to expand its influence on the Surrounding lands. It first started with putting the remnants of the Levant into its sphere, and while it worked with Aqaba, it didn't for Eilat, which was trying to rebuild Jerusalem and re-establish Judaism as a world Religion. South of Arabia, Yemen and Somalia - you guessed it - exploded, with Riyadh taking over North Yemen in its goal of spreading influence, while Somalia was shattered, with Abu Dhabi, Nairobi and Addis Ababa thinking it would be a good time to intervene.
With little areas for expansion, India instead turned to expanding its realm and establishing dominance under the world. It is the Indian Ocean, after all. New Delhi started by bringing its bordering nations under its influence, before intervening in several wars and sending exports all over the world. While Sri Jayawardenapura Kotte, Kathmandu, Thimphu, Male and Dhaka ultimately fell into Indian submission, Islamabad and Naypyidaw refused to, instead deciding to go their own ways. Pakistan found itself squashed by the Hindu Kush, while Myanmar expanded itself alongside the Chao Phraya and Mekong, an act not welcomed by the reformed Thai government in Phuket. The virgin Indochina gave the Rohingyas the chance to escape genocide, forming the nation of New Arakan on the Red River. Even after an Indian-assisted coup that led to autonomy being granted to non-Bamar areas, they still stayed there. Below them, Indonesia was trying its best to rival New Delhi as the major power of the Indian Ocean, but ended up being in competition with Malaysia & Singapore, while Mauritius decided to act on its claim to the British Indian Ocean Territory, successfully conquering the territory in under 3 days.
The Americans, now having nowhere to observe the political situation, decided to travel across the Timor Sea and established a Colony in Arnhem Land, which led to some ire from the Aussies. Speaking of which, Australia had a hard time trying to pull itself together, arguing whether it should be led from Perth or Adelaide. History repeated, and eventually a new capital city was constructed, named Noongaria after the dominant Indigenous population. With the capital city issue solved, the Australian remnants went out to resettle their Wild East.
