There's no doubt that Boko Haram has been driven from many of its strongholds in northeastern Nigeria. Now, President Muhammadu Buhari says technically, we have won the war. Those in the know say but technically, the army is still losing the battle because Boko Haram has changed tactics. Instead of now holding territory as it used to and calling this territory its own, now it is resorting to guerrilla tactics, hit-and-run raids and especially suicide bombings.
