Why suicide? If objection is because narrow pass not militarily defensible position, against a future surprise attack, that will cut Artsakh off , then yes perhaps. But even in this case, the buffer around the pass can be extended, in exchange for land in Artsakh, owed to Azeri citizens, displaced after the war. Armenia gaining in land around the pass. Alternately if objection is about the indefensibility of Artsakh, as a whole in Azer. Then solution could be to exchange it for Nakichevan. They are approximately the same size.
".... There will be ethnic cleansing if the Turks have any say in it. Quite who will be moved in is a different issue. The advance party already there?......"
The bulk of the fighting is around Artsakh. Rather than Azer lost territory. This tells us that motivation behind Azeri offensive, is not regaining lost towns. But driving out Armenians. Ethnic cleansing. So it seems Turks are pulling the strings, as you said. Removing Armenia from map.
