The government of Nigeria and it's people should work as a team and  have to make an assessment on determining the root cause of these atrocities and find possible solutions but I know this is not that easy because this has been happening for so many years now. We foreigners cannot exactly give you the accurate solution to this problem because we are not from your locality but yeah my country was also fighting terrorists for so many years but the government is really serious in eradicating these insurgents. They do have campaigns to encourage these rebels to surrender and they'll provide them livelihood, house and education for kids and some of them even joined the military as they diverted from wrong belief and these surrenderies are now helping the government to capture their former fellow cadres.
