How the course of history would be different if Antarctica was habitable?
Let's imagine Antarctica remained as a continent with normal temperature and relatively green area as it used to be 90 million years ago.
In my opinion, it would be a single continental state like Australia, but with a swampy geography like Russia. It would have a population of 40–60 million people. Initially, it would have ancient indigenous tribes, but later, it would be under the Spanish Empire, thus becoming a Spanish-speaking country. It wouldn't participate in either of the World Wars, and after 1945, it would be a neutral country where states would organize meetings and sign truces very often. It would have a medium impact on world history in the post-colonial period but would gain remarkable power in global markets and world politics in the 21st century due to immense possession of natural resources. It would become one of the richest countries on the planet. Its passport rank is (most likely) the same as Brazil's. Western Antarctica would have fascinating views because of its mountains, becoming a hot tourist spot. Finally, I believe it would be a "Western" country with more neutral politics than any of the world's superpowers. I don't know about the religion, though... perhaps Christian-majority.
What's your opinion on this?
