Public affairs analyst Mahdi Shehu has criticised Nigeria’s Minister of Defence, Christopher Musa, over his call for a physical border wall to curb terrorism and cross-border crimes.

Shehu argued that only an “invisible wall” of justice and equity can safeguard Nigeria from disintegration, dismissing the minister’s proposal as outdated and disconnected from modern security realities.

In a post on X on Friday, Shehu said that advocating concrete walls along Nigeria’s borders demonstrates a limited understanding of history, geography, and contemporary warfare. He highlighted historical walls such as the Berlin Wall, the Great Wall of China, and Jerusalem’s Wailing Wall, noting that none provided lasting security.

Shehu also questioned the feasibility of the project, pointing to Nigeria’s long, porous borders and neighbouring countries facing their own challenges. He emphasized that modern warfare relies more on technology, intelligence, and digital surveillance than physical barriers.

“The invisible wall of justice and equity is what will truly save Nigeria,” Shehu wrote, adding that Musa’s suggestion seems driven more by the potential budget for construction than by practical security solutions.
