Important question raised here imo, and I can relate.

My country of origin has hundreds of tribes, languages, and different cultures. From afar, we appear as a country with a flag, a national anthem etc, but from within, tribal identity is undeniably very strong.

Two provinces have started a secession war 3-5 years ago.

Africa's artificial borders have always been a source of instability, and it's a real and urgent problem every where you look.
