There are many ways the problem of insurgencies and insecurities can be resolved in Nigeria.
(1) Respect for Human Lives
Many people in Nigeria both our political leaders and the other citizens do not respect and value lives. If a reasonable human values the life of his neighbors, I do not see the reason while he should kill them.
Also, if our political leaders value the life of the people they lead, there is no way they will gamble with the life of the citizens. Nobody will cause social disorder in society if they really value the lives of the people.
(2) Avoiding religious Blindness
Have you ever seen a sick woman whose children want to take her to the hospital for medical treatment for her to be fine and she refused saying that her problem is spiritual and holy oil from her place of worship will heal her? She keeps dying due to her religious blindness until the issue gets worse. That's is how religious blindness has caused much harm to people.
In the same line, one of the major reasons for insurgencies and insecurities in Nigeria is because of religious blindness. Many Nigerians are blind to religion to the extent of killing their fellow citizens because of the wrong teaching by their religion.
(3) Job Creation
An idol man is the workshop of the devil. Many minds which are not busy with good things end up becoming threats to society. The people become criminals and kidnappers and become a threat to society. The government and individuals should create jobs to reduce this.
(4) Education Promotion
There should be a proper promotion of education in Nigeria. When a large number of citizens are educated, they will not practice some things that can lead to insecurity in the country.
