>>93380725Yeah the environmental issues would likely be a huge point of contention between Atlantis and the Surface. Its not just America that would be the pissing them off, its nations like India and China too.
The emergence of Atlantis would have a bigger effect upon the world than that of Superman. Superman raises deep philosophical and legal issues, but Atlantis upsets the entire world balance. They are a military power equal to or greater than the USA, hugely advanced and in terms of resources, the wealthiest nation on the planet, bar none. They could almost certainly claim a position on the P5 of the UNSC - IRL there are talks of expanding the p5 already, and Atlantis has a better claim than any nation currently being considered. Then you have nations looking to make trade deals, hoping to gain access to resources and Atlantean tech. Atlantis could probably secure a good trade deal with the EU (and post brexit UK). They would likely be a very aggressive supporter of environmental issues. A deal between Atlantis and BRICS (though not likely Russia) exchanging resources in return for more stringent environmental standards. Fishing rights would be big. If Atlantis strait up refused to let nations fish in their waters the impact would be serious. Not only the economic reproductions but a huge amount of food just strait up vanishes. Its not just the fish that vanish from the markets, but fish are often used as feed for other meats and as fertiliser. Could well spark armed conflict.
>>93380810The general military seem to be basically identical to current IRL standards, so I think the effects would be marginal, given that Atlantis itself has some technology and magics of its own. I also didn't really include much speculation on the actions of metahumans, e.g. the League. As Atlantis is a sovereign nation the league would normally have too keep out of the conflict, but in practice they allow the USA/IRL nations far more leeway than the fictional ones.
