I have also considered the stakes and realized that core North won't give up on their stranglehold on Southern Nigeria except they are forced to. The way Nigeria currently is, is Utopia to them since they know they're getting everything absolutely free from Southerners while equally using us as slaves. Almost everything of economic value is domiciled in the South while the North controls it all. The seaports, oil and gas resources, economy, human resources etc are all in the South while the North is almost collapsing under the weight of overpopulation, abysmally low productivity, poverty, all indices of development/growth in the negative, banditry, Boko Haram and near anarchy. Virtually all the sectors that earn Nigeria its fame are in the South such as Nollywood, music, sports, diaspora exploits, economy and industry, natural resources and all positive human development indices. The North will automatically sink into failed status the day South breaks away and they will become obscure like Niger, Chad, Mali and other Sahel countries, only to be remembered because of the activities of Islamic terror groups. All these realities I mentioned above is not lost on them and that's why would rather die in their millions than allow South to peacefully break away. That's the sad reality but should the South fight together as one, they will defeat the North in war with absolute ease in the long run. We have the brains and resources to rout them and they will be at a serious disadvantage since they won't have access to the sea to bring in heavy war equipment. Also, with a largely poverty stricken populace that will sink deeper into crushing poverty, coupled with Christian minorities that will rather fight against them and break free than fight on their side, they won't be able to resist for too long before giving up. The South is just a willing slave with terribly selfish politicians who allow themselves to be manipulated. The North is only relying on propaganda and manipulation to scare South from uniting and fighting them.
