War. What is it good for?

Although war is inevitable, I don't think that countries should be so eager to start or become involved in the violent fighting. Yes, war can be necessary in some situations, but it remain between those who it effects. Surrounding countries shouldn't become involved. Nothing good can come out of a war full of countries fighting with their allies over something that occurred between two countries and could have been resolved quicker and easier than a world war. I do not believe that the violence of war is morally acceptable. It would be ideal for problems between different groups of people to be resolved through peaceful compromises, but it is obvious that this is never how the world will work. Because of this, war will always occur, but the extent at to which it is taken can be lessened by the neutrality of other countries. I personally don't know when a country should declare war. It is solely based on the situation and how offended or hurt a country is, and it is there decision whether or not war is the only thing that can fix their problems.
