Why wars are not good ways to end conflicts between two countries?

No, wars are not a good way to end conflict between two countries or individual. Wars bring destruction and nothing else. It results in the loss of resources as well as lives. Wars are not the solution of any conflict. Mutual understanding and conversation are the basis of better results for any conflict. Wars bring down the economic conditions of the country as well. Throughout the history, no war has ever ended a conflict. One war has either led to another war or cold war or war-like circumstances. So wars are not at all a good way to end conflicts between countries or individuals.

Gandhi won a war without even fighting one.
