No, it's against international law to claim any part of Antarctica as territory of a nation. There are research outposts, but they are not considered territory of the nation that operates them.Of course, instead of just rebelling against a nation that claimed Antarctica, now the Antarctic Union is breaking international law that has held for over a hundred years (I think). Meh, it's 2070, the Antarctic Treaty might have just been forgotten. Along with basically everything else we have, including the Geneva Conventions.

Actually there were sovereign claims before and still are. The UK subscribed the Antarctic territory as one of its 14 oversea territories... Giving it the same status as area's like Gibraltar and the Falklands... Yet also signed the Antarctic treaty. In addition. I believe France integrated theirs into the same office used to administrate French islands, but also signed the treaty.

In other words, their claims are pretty much indistinguishable from their claims on various islands... But they also signed a treaty stating they are not sovereign lands.

If I remember correctly, either the Brits of Argies named their claim... Which overlaps with the other and resulted in tensions in addition to the stink about the Falklands being risen by Argentina again at the start of the 2010's, and it turned into a little bit of a territorial argument between UK and Argentina, as another side show to the Falklands... Cant really have a territory dispute if you don't own the land (Basically the Argies started whining about how it was unfair they lost in the 80's, and eventually shut back up again after the Falklands held a referendum where only 2 were against being Brits rofl)

The entire thing is a big political mess, and technically the UN collapsed and its treaties are void anyway, so its not unreasonable to think some might want their claims formalised (A nice huge chunk on the map fir for... And an isolated place to hide away those top secret projects)
