Refer to the passage. "WHEREAS we have been in the vanguard of the national movement for the building of a strong, united, and prosperous Nigeria where no man will be oppressed and have devoted our efforts, talents, and resources to this end;

WHEREAS we cherish certain inalienable human rights and state obligations such as the right to life, liberty, and pursuit of happiness; the right to acquire, possess, and defend property; the provision of security; and the establishment of good and just government based on the consent of the governed;

WHEREAS in practical demonstration of these beliefs, our people settled in other parts of Nigeria, served their country in many capacities, and contributed immensely to the growth and development of Nigeria;

WHEREAS WE ARE LIVING WITNESSES OF INJUSTICES AND ATROCITIES COMMITTED against Eastern Nigeria, among which are the premeditated murder of over 30,000 of our innocent men, women, and children by Northern Nigerians, the calculated destruction of the property of our sons and daughters, the shameless conversion of 2,000,000 Eastern Nigerians into refugees in their own country, all this without remorse;

WHEREAS in consequence of these and other acts of discrimination and injustice, we have painfully realized that the Federation of Nigeria has failed, and has given us no protection”
