No, war will not bring social order, because war is naturally disorder. A person cannot make something by blowing something up. A war breaks down society and its social structures. To rebuild, the society must start over with its social orders. There is no such thing as rebuilding by allowing a society to hit rock bottom.
War will only bring more negativity to society and those who we go to war with will always hold some sort of grudge against us. We want to join hands through positive ways and we should seek getting things done in a civil matter. Sooner or later if war is used we will see that things will only get worse for us.
