War is a primitive state of mind solely based on an ignorant side or sides. Since that is the case, war has been declared by many groups, nations and individuals over times past and present. Many of the reasons, most of the time, not even being logical or rational. With that being said, our only means of abolishing war is through education, communication and understanding, not in any particular order. Not to say that would ever happen in this dimension, but anything is possible. God please give us the wisdom!
