Nigeria was created out of many tribes been combined into 1 country.
for those who are screaming for division .why should it be into south/north?tribally in the south we have many different tribes.
economically maybe the niger delta have a reason to be a country to maintain themselves as a big voice in the oil industry despite been from many small tribes .but why would they want to be in the same country with ibos or yorubas ?they will likely dominate and still be taking the oil share.
honestly any divison in nigeria can only lead to civil wars and further breakways.
better to stick it out and try and repair what we have been for decades and become a powerful force again in africa.
