War is Necessary for Some Reasons Some say that war is "a necessary evil ". Others say that war can be avoided by using peaceful means . I think that war is a necessary evil for 3 reasons. First, you will go to war if another country attacks you. Let us imagine, if another country attacks you for some reason, peace cannot solve the problem; war is necessary. Second, countries will go to war for some serious disagreement that needs to be resolved . For example, these days China and Japan have a disagreement about the Diao Yu Island. If this argument can't be resolved during a period of time, war will probably occur between these two countries. Next, if a country is attacked by another country, and you want to help that country, you will go to war. For instance, America and England are good friends . If America needs to resolve some problems by war, England will want to help them. So, England will join America. In fact, every war needs to achieve some purpose . There might be a political purpose , economic purpose, or some military purpose. Each war needs a lot of soldiers, weapons, and money. War is very harmful to citizens . Many people died in wars. So, we don't want war ,but sometimes we must have war . If another country attacks , if we need to resolve a serious issue ,or if another country needs help ,maybe we might go to war.
