Also speaking, former President Olusegun Obasanjo said Nigeria must learn from the “black days” of her history to strengthen the unity of the country. “Occasions like this should strengthen Nigeria’s unity, Nigeria’s common security, Nigeria’s shared prosperity, Nigeria’s togetherness for the greatness of our country,” he said. Former first lady, Patience Jonathan, said the memorial was to celebrate a hero who stood for and died for Nigeria’s unity. Former Chief of Army Staff, Gen. Azubuike Ihejirika, described Ironsi as “a patriotic Nigerian,” adding: “I am happy that Nigeria has recognised a man who believed in Nigeria’s unity.” “He died for Nigeria’s unity and I hope we will achieve that unity,” he said.
