Are Guerrilla wars really necesary?

"We are being discriminated,we are facing racialism,we are not trated fairly,our rights are being trampled upon,we want to be autonomous,"these are some of the few criesof the people engaged i guerrilla wars.In writing this piece I have concurred to one of the dictums of J.F.Kennedy that"the highest duty of the writer is to remain true to himself and let the chips fall where they may."Guerrilla wars are normally organised people few indeed in their numbers with little or no support from the majority of the populace.It is poltically-oriented,a very militants or paramilitary occupying the enemy's territorial borders.Due to their number they find it very difficult to conquer the state military instead sought to different ways which are in the best form of harrasment.Hiding in caves,ambushing,disconnecting power and telephone lines of their enemies from their hiding places in the bushes and what have you.They do receive support from different militants,others in the form of food,shelter,clothing and so on.However,the argument here is whether the guerrilla wars are really necessary and the best alternative method for the aggressive and violent people to have their voices heard,and also are the past and current government in support of this act?
Guerrilla wars started time immemorial,in the centuries,as far back as in the 17 through to the 19th century.It was seen in the Vietnam war(Indochina war),Persian War,Spanish war,the great war,second world war,and the rest.It has being backed by some leaders like the first president of the republic of Ghana andI quote"African guerrilla are necessary if socialist aims are to be achieved.",Malcom X also said that"we are non-violent with those who are non-violent with us".In this our politically-oriented world where politicians control the natural resources,ever little thing they do sort to subvert the lives of their opposers since they all do practice the act,winner takes all.In rendering the rules of the winner takes all,the policies enacted are negatively skewed causing very much people to be marginalised.They enact policies which do not attain the highest good for the highest number of people.The question still rolls.To add an addendum or not the question goes to folks with whom I have the same mental vaculty with to help debate this motion.
