Can Alaska even survive as an independent nation?
I think the US annexes parts of BC and Yukon to make a land bridge to Alaska before it gives it up. I'd see it giving up on rural parts of Pennsylvania, all of WV, and Illinois first. I know there's no mechanism for a state to secede, but what about splitting into parts and only one part keeps the state name/legal status, and the other part just becomes a landlocked entity that has to pay a protection racket but gets $0.00 in federal funding back?
Alaska with its oil, refineries, and spots to park radars make it too nice of a place to hold onto. If in some misguided attempt to Own the Libs or whatever the US did split off Alaska, then whenever someone got up there from CONUS again they'd find English as a third language, if it all, with Mandarin second and whatever native tongue as the first language.
