Nigeria has faced numerous internal conflicts, including the Boko Haram insurgency, banditry, and kidnapping. President Mohammadu Buhari has invested heavily in security personnel and equipment to contain the growing threat. However, the incoming administration of Asiwaju Bola Ahmed Tinubu faces a huge burden and needs to lay the right foundation to sustain and build upon the gains made in the past few years. The Nigerian insurgency has experienced significant attacks, including the 2011 bombing of the UN building and the 2014 kidnapping of over 200 Chibok girls. To achieve sustainable development and achievement, the incoming administration must prioritize tackling insecurity. The National Security Adviser (NSA) should have a military background and command international respect based on personal and professional achievements.
