If the world had to be limited to no more than 50 nations who would the "survivors" be? How would the diplomacy/wars (no nukes) play out.
Okay, there are a few areas that could even prosper, and many that would most certainly not. I'll do my best to break it down into regions.EuropeI expect that the EU would become a unitary nation pretty quickly to prevent from any outside threats, or internal wars. Smaller non-EU countries that couldn't form their own empires would likely be gobbled up pretty fast, although Switzerland may remain in its current state, considering how ridiculously defensible it is, particularly when nukes aren't used.The UK would most likely merge with the counties around the world that still have the queen as head of state. This would probably also involve a rebranding to being called ‘The Royal Commonwealth of Windsor• or perhaps just ‘The Commonwealth’. It would likely keep Ireland around, the last thing it wants is another Troubles.A couple surprises could come up, perhaps A Franco-Low Countries union, a united Iberia, a new Scandinavian Republic. To make this more interesting, we'll say all 3 arrive.Iceland would likely also remain independent.Middle EastWould likely descend into Chaos rapidly, which the main fighting being between the Saudis, Iranians, Iraqis and the Turks. Likely each nation would aim to create an Islamic Kalaphate, aiming to unify Arabia. Probably would end up with a seemingly Endless war between two Sunni Kalaphates (lead by the the Saudis and Turks) and a Shia one lead by Iran. (Hopefully my sources on this were accurate, my middle Eastern knowledge isn't perfect).AfricaProbably would end up being divided into a few countries, a South Western bloc, lead by the Nigerian government.The Egyptians would invade as much of North Africa as possible, either diplomatically or by force, they could run into some issues in the west, where the Iberian Alliance may attempt to move into Morocco to expand the buffer between them and other African countries. They would probably become rather powerful, taking Sudan, South Sudan, Eritrea, Somalia ect. It could run into some issues further south, as there is already speculation of a new county forming soonish from a few nations in the subsaharan East. The East African federation may work with the Iberians and West Africans to combat the Egyptian threat.The Commonwealth would likely move north from South Africa, taking Lethoso, Angola, Zimbabwe ect.Madagascar will likely remain independent.North AmericaWith Canada in the Commonwealth, the United States would recognise a need to showcase it's southern power, it would invade Mexico, and despite significant internal strife due to the number of Mexicans in the US (approx 10% of population) it would nonetheless be triumphant. It would continue to move southwards, which could lead to a Central American Federation, although this would likely not survive too long. The US will continue to push into South America for decades, at least while Venuzuela has oil.The Caribbean Nations may form a new nation in a bid to protect itself, it may have some luck, although in the long term may struggle.South AmericaBrazil would likely prove itself to be quite capable, although language issues could prove a challenge as the rest of SA uses Spanish, not Portuguese. I can see most of the Spanish Speaking nations unifying, creating New Hispania. The country would likely have close ties to Iberian. It it cannot find Allies, Brazil would probably remain a standalone nation. Perhaps due to the Iberian Union, it could end up convincing Spanish speaking nations to join it.I'll say that it remains alone, but with close ties to its neighbours.Asia/OceaniaRussia, The Commonwealth and China would be battling for control of mainland Asia. Russia may push to reclaim the - stan countries of its USSR days. China would quickly pull a Tibet on Mongolia, while Nepal and Bhutan are quickly eaten by the Brits. Pakistan is taken into the commonwealth, but Afghanistan is taken by China. Indochina is split, Vietnam and Laos joining China, while the commonwealth, after absorbing Bangladesh, would take Malaysia, Thailand, Myanmar, Singapore and Cambodia.Meanwhile, Japan is making power moves, it reinvaded Korea, the Chinese and Russians are spread too thin, so let it slide. Taiwan, The Philippines, parts of Indonesia, Brunei and Papau New Guniea are taken, the rest of the islands in the south going to the Australian Commonwealth fighters.The Pacific Islands not taken by the foreign countries create a Polynesian alliance.Sri Lanka and the Maldives strike a deal with the Brits for their independence.The WorldI've gotten really into my world here, so I'm gonna make a crappy map tomorrow, so keep an eye.
