There's really no reason for any nation state to make any kind of claim to Antarctic Territory.
In addition, the Antarctic Treaty forbids additional claims, while holding existing claims in abeyance. The treaty preserves all land south of 60 degrees S for science, so any existing or future claim would have no other value.

No part.
No foreign country owns any part of a US state.
I suppose , like any country , Ireland owns its embassy in the USA.

Honey, the US doesn't own any part of Cuba. Back in the day, they had a little thing called Guantanamo Bay that they're still holding onto like a bad ex-boyfriend, but that's about it. Cuba is doing its own thing, sipping on mojitos and dancing to salsa music, without Uncle Sam's ownership looming over them.
