   A DOCTOR'S JOURNAL  ENTRY  FOR AUGUST 6,1945(SUMMARY)    Vikram Seth's poem is a dramatic monologue which outlines the impact of the dropping of the atom bomb on the city of Hiroshima,as seen through the eyes of a Japanese doctor that day.Obviously the poem is anti-war and criticises such an inhuman attack that almost destroyed the city and took tens of thosands of lives.War is a inhuman and brutal thing.It results in destruction and suffering.The images created in the poem stir the feelings of the reader.    A rather surprising thing is Vikram Seth's choice of the subject of his poem.This incident occured much before his life time and thousand's of miles away from his homeland(India).But that Seth should have chosen this incident proves that war and its impact is not limited to national boundaries.War is and will always remain a universal disaster.    The speaker is a Japanese doctor who is relaxing in his home on...
