Unlike other federal systems; the current Somali states won't agree on the final constitutions until they've been given rights as a sovereign nation that only shares a flag with Xamar.
That's just plain fear mongering. It's actually the federal states that are pushing for the completion of the constitution, with the SFG delaying it for nearly 6 years now since HSM was chosen.
You can't even say that the federal states are in the wrong because there's isn't constitutionally or even textually clarity on what the division of tasks between the FS and the SFG is.
