We live in a world which is a global village, and we are all interconnected. In an interconnected world, everything affects other things too, either in a positive or negative way. Just like the whole body of an individual suffers when part of a finger is bruised, similarly the whole world is affected even if there is violence in only a particular area. So, one also gets affected by the happenings in another country. Therefore, it is impossible for peace to prevail in other parts of the world when even a part of it is in turmoil.
