“I have not failed. When we came in Boko Haram was effectively in 14 local governments. Nigeria has 774 local governments. They hoist their flags and they said they had a certain caliphate but today they no longer to hold any local government. 
They have reverted to improvised explosive devices blowing soft targets, and that will be a kind of terrorism which will be difficult to eliminate because it is technological, but they cannot hold any local government again. They are using technology but they cannot carry out organised attacks, overrun police post, attack military installations, they cannot do that now.”
