Personally I have come to reason why the boko haram insurgency will never come to an end anytime soon in Nigeria and why they never stop killing in the country,Boko haram was created and fund by some northern politicians to disrupt Goodluck Jonathan's adminstration,fortunately they succeed because the north saw Jonathan as an Igbo man which is their most annoyance as they never want to see an Igbo man to become Nigerian president,then after Buhari a northerner won the election in 2015,they where called to stop their attack by those who created and funded the group,after some close door meetings with the group they made some demands from the creators before they can stop the attack which collapse

1.They demanded a lot of money which was not granted by their creators.
2.They demanded to be fixed in some important ministerial seat.
3.They demanded to allow to islamize the hole country by their own faith, e.t.c

They are only enjoying leakage of vital informations from their perceived opponent.if not it won't take the army 1month to finish them.
