I still think war is necessary because in this world, there are many unreasonable people and some of these people rule countries. For example, Hitler had no sense of reason and murdered millions of people. In order to protect ourselves, we must use force against these unreasonable enemies. In a perfect world, war would not be necessary, but our world is very far from a perfect place. War has given us our freedom as well as many other things.
Moral war is war that is made to protect people.
Immoral war is war that is made by not protecting people. Immoral war will happen whether we like it to or not. We must realize that we must use moral war to stop it. It would be great if we didn't have to go to war for any reason, but in reality, war is necessary to protect ourselves and others.
