SNM stands for Somali national movement right. So in the early days this movement their intention was not to separate somaliland from greater Somalia or am I wrong?
Pretty much, but the more clanist faction that were fighting in SNA overpowered the nationalist who supported a united Somalia. This was due to the fact that none of the factions in Somalia, after the overthrow of Siad Barre. The different factions were not able to agree on to a power sharing forumla. Mainly, USC that captures Mogadishu disraged the idea of decentralising power to the other regions.
Hence, the nationalist factions who goal was to overthrow Siad Barre but keep united Somalia were delegitimise. As showing the "south" was not willing to share power. So nationalist were overpowered by the more Clannist faction that wanted to breakaway from Somalia. With the support of Derg (Communist Ethiopia), the Clannist defeated the nationalist and the northwest of regions declared independence.
Main reason why Derg supported pretty much all the factions in Somalia. Goal was to balkanise Somalia into clan Gordon. This concept worked in the northern regions. But failed in South central Somalia because of clans being to intertwined (economically, historically and politically).
But a couple months later. The Derg themselves were overthrown by ethnic factions that Siad Barre was supporting. Which the goal was to balkanise Ethiopian by adopting Ethnic federalism and allowing succession. This worked, and now Ethiopia is dealing with potential threat of the Tigrays and Somalis who are the most likely to declare independence from Addis Ababa. Hence, why recognising Somaliland has potential to trigger the balkanistation f Ethiopia.
Main reason why Somaliland never gained recognition from Ethiopia. Who has the most interest in see a weaker Somalia but because Ethiopia is dealing with sucessionist calls. Ethiopia is in no position to undermine the unity of Somalia.
Simply but it, the Cold War left the Horn of Africa in a stalemate. Neither Somalia or Ethiopia can politically undermine each others unity. It's up to both countries to reunite their populace back into one centralise state.
