I don't think it's too late for SL to return to the fold and reconstitute the Somali republic.
Start with a state visit of Cheeseman to Hargeisa. Negotiate (better than the 60s) the federal status of SL, wherein we retain a lot of autonomy and we get to keep our territory and minorities
We ought to politik so as to sideline our rivals within somalia (you know who you are) by becoming the dominant and an important partner to the FGS and ensuring a power/kingmaker position by like helping militarily, economically etc etc
We would enjoy local sovereignty and autonomy under SL, along with
Somali Republic passports.
Xamar politics is unstable and weak right now, if SL politicians were smart they would game and finesse the system but we've been cursed with lazy incompetents with laangaab mentality
