Bola Tinubu on Saturday demanded an urgent arrangement of a national dialogue to discuss Nigeria’s peace and security, saying his analysis of prevailing affairs has shown that President Muhammadu Buhari and other top administration officials have failed to address killer herdsmen and other debilitating security crises. Mr. Tinubu, a member of Mr. Buhari’s ruling APC, said it was imperative for policymakers to first roll back acute insecurity before implementing progressive economic measures for the country’s estimated 200 million people. Mr. Tinubu’s statement, which came in a Twitter chain on Saturday night, sought to strike a balance between the killer herdsmen activities and the push from southern Nigeria for the exit of Fulani as a silver bullet to banditry, kidnapping and other violent crimes. The former Lagos governor said both sides of the crises have an enduring stake in Nigeria’s co-existence and should be allowed to first meet at a national conference to propose sundry solutions that will be acceptable across the spectrum. Mr. Tinubu previously saw himself as a part of the Buhari administration, but the politician has made statements that cast him as an outsider of late.
