The poem is obviously a strong plea for universal brotherhood. It underlines the fact that the people of different countries have same physical, mental & emotional experiences. Their fate is the same. They are in no way different even though they wear different clothes & speak different languages. Nobody should be viewed as stranger & no country foreign. The poet emphasises the futility of hating those who belong to other countries. When we wage war against others, we only defile our own earth. The dust & smoke caused by war weapons pollute the very air we all breathe. Thus we should never fight with others. We should remember that all of us are the children of the same God. When there is no essential difference between us & them, where is the room for hatred, violence & war?
