In the past, the world has faced two deadly wars. During World War-1, the total number of military and civilian casualties were about 4 crore people with an estimated 1.60 crore deaths. World War-1 lasted for about 4 years 3 months.
World War-2 lasted about 6 years. It directly involved more than 10 crore people from over 30 major countries. Over 6 crore were killed which was about 3% of the 1940 world population. By 1945, the war in Europe was over, however, in Asia, Japan refused to surrender and thus on 6th August 1945, U.S.A dropped an atomic bomb on Hiroshima and three days later another bomb was dropped on Nagasaki. The single bomb on Hiroshima killed 1.40 lakh people immediately. Witnessing the destruction, Robert Lewis, the co-pilot of the U.S.A bomber later wrote, “My God, what have we done”.
That horrible bombing as mentioned in the words above, continue to resonate world wide even today. Hiroshima and Nagasaki remain the only time atom bombs have been used in war.
The massive destruction, contamination and human suffering from these attacks had an even broader impact by successfully deterring countries from using such bombs again. The world became aware of the terrible consequences and this was very significant.
The past (atom bombs used in a war) have a very important lesson for all of us that the future will be disastrous if we continue to use such weapons in wars.
