Somaliland is nothing like South Sudan or Eritrea. Support for secession in northern Somalia is no where near where it was in Eritrea and South Sudan in 1993 and 2011. Eritreans voted for independence by an overwhelming 99.83% with an unbelievable turnout of 99%. South Sudan voted for independence by 99% with a turnout of 98%.
These are not bs African election numbers, this carefully monitored referenda, where Ethiopia and Sudan had observers in every single polling station.
Somaliland never has and never will achieve that level of support from Harti, because the SNM was an explicitly clan based movement while the EPLF and the SPLA were truly national liberation fronts where Muslims and Christians, Dinka and Nuer died side by side for 40 years. No Harti has ever died side by side with an Isaaq.
The funny thing is that these referenda have turnout thresholds. In South Sudan the requirement was 60% turnout, at least 60% of voting age adults had to go to the polls for the referendum to be of any significance. In 2021, Somaliland would probably be able to clear this hurdle, but it will be an impossible one to clear in 2030 if Harti as a whole and maybe 30% of Gadabursi boycott the referendum.
Also the clock is ticking.
