WHAT COUNTRY IS THIS?

Counterweight to the Pharaohs.
Famed black Pharaohs.
Ruled Egypt but not acknowledged by Egyptians.
The bane of blackness continues.
Home of tall, ebony black people in the South.
And lighter Arabinoid people in the North.

Huge landmass.
Cleaved in half after a long internecine conflict.
Lower half still engulfed in vicious intertribal conflict,
With no end in sight.
Conflict fueled by neighbors,
And petrochemical politics.

Leader indicted for war crimes,
Sheltered by the African Union.
Skirmishes continue in low grade guerrilla war.
Inside the country, after the excision of part.
Maybe excision, not always a solution.
Astonishingly, war continues in the new nation.
