The question of profitability depends more on the architecture and core design of the project, and less on the external market troubles.
A properly designed Alaska Gas Project takes all of the external market troubles and global issues into account.
Any type of war & peace scenario is jut a small part of the BIG PICTURE.
A big-whopper steel megapipe ugly twin sister gasline to TAPS is doomed to failure.
Thinking of AKLNG with LNG dominant is doomed to failure.
A properly designed Alaska Gas Project can be very profitable for Alaskans.
IMHO:  All of the expensive studies compiled on AKLNG are worthless.
1974 I designed a profitable & scalable gas pipeline from Deadhorse to Fairbanks, and I charged $20 a copy [ a burger and beer ], and I charge the same for it today..

Today my AK Gas System Design is much more complex, but it sure as hell doesn't cost $billions in CAPEX before it shows a profit.
