If the PM of Somalia visits that ‘disputed’ region but Somaliland officials can’t visit, it completely annihilates your narrative of being an actual state with borders. This is why the Isaaq internally displaced parliamentarians in Xamar like that lady with the fanax, Gunsan, and the Shaquille O’Meal looking 1st deputy PM Saalax are vehemently against this. I can feel your panic through the screen.
If you were a unionist this a provokation that makes reconcilliation between the two countries harder. I think the FGS is too beat down for reconciliation they are doing it in part to project power for their domestic audience (read Xamar).
Borders are legally defined. I'm sure there are groups in many countries that would work with neighbouring countries to further their own cause, being on the border makes that possible and easy.
So really FGS is stoking a rebellion in neighbouring Somaliland for domestic reasons (to appeal to their constituents in the capital).
