In groups discuss whether wars are a good way to end conflicts between countries. Then present your arguments to the whole class.
Wars are definitely not at all a good medium to end conflicts between countries as they do not lead to any solutions except 'n' number of killed sodiers, orphan children and widow wives. Man is a social animal and likes to live in a society. If any kind of conflict occurs among each other, he solves it either by discussion or legally. But if conflicts arouse between two countries they are solved only by wars. Why? Why can't some other solutions be found? We have brain and so do the politicians. They are civilised and educated people. The conflicts can be solved by talking to each other or by apologies. Wars lead to enmity and leave a forever, never-to-be filled gap between the two nations. So wars should be avoided.
