War can never be good. It causes loss of life and property. Physical properties are damaged due to the war. Developed or constructed infrastructure are damaged while new construction cannot begin during the time of war. For example, the second world war lasted for about 6 years. About 22 million people were killed and 1.1 Trillion US dollars turned into ashes in this war millions of people were injured, maimed as well as homeless.
Therefore, any problem should be settled through peace talk and understanding. Germans developed the feeling of revenge as the dialogue and understanding did not became fair due to which the second world war occurred. Several dialogues were held towards the last of the second world war to avoid such weakness. Atlantic charter is another example of it. The formation of UNO was possible based on the Atlantic charter. UNO has prevented world war till now since it was established.
Therefore war cannot be the solution of problem it is dialogue D understandings.
