In groups discuss whether wars are a good way to end conflicts between countries. Then present your arguments to the whole class.
Wars are certainly not a good medium to end conflict between nations at all, as they lead to no alternatives except for the amount of murdered sodiers, orphaned kids and widow husbands. Man is a social animal that enjoys living in a community. If there is any dispute between them, He solves it either legally or through debate. But if disputes arise between two nations, only wars will solve them. Why? Why can't you find any other alternatives? We have the brain, the leaders do likewise. They are individuals who are civilized and trained. Conflicts can be resolved by speaking or apologizing to each other. Wars lead to enmity and leave a gulf between the two countries that will never be filled. Therefore wars should be prevented.
