Bombing at Hiroshima and Nagasaki: How the Great Civilisation works

A few days ago, I was watching a movie named “Aagntuk” from Satyajit Ray in that movie the lead actor portrays as a person who is a traveler and explored to a different culture that makes his mindset very different and when he was asked what you think of civilization? Don’t you like to be civilized? Does he reply to it is a civilization that takes life and asks the questioner if bombing out Hiroshima and Nagasaki is a work of advanced civilization? It inured me and led me to find whether the cost of maintaining civilization or to show more civilization means destroying another civilization. Do civilization means destruction, war, and colonization.
We all aware of the bombing of Hiroshima and Nagasaki which bring the Shame to the United States and the United Kingdom till now how just to prove themselves more powerful they killed people between 129000 to 226000 most of them normal civilians. The two beautiful cities of Japan suffered the most for remaining calm.
The United States denoted two nuclear weapons over Hiroshima on August 6, 1945, and Nagasaki on August 9, 1945, with the consent of the United Kingdom as required by the Quebec Agreement.
So what you think that after doing this the world shamed and accused the Manhattan project which designed the attack, Alas you are Wrong Leslie Groves was the person who was the man in charge of the bombing process he conducted the same but he was awarded several awards for doing this.
After the atomic bombing of Hiroshima and Nagasaki become public Knowledge he was awarded the “Distinguished Service Medal” and not only this in recognition of his work Belgium Government made him “Commander of the order of the Crown” and the British Government made him an Honorary “ Companion of the order of the bath”
Indeed, to safeguard the border of a country Arms and troops required but is the killing of innocent people in the name of War is the work of civilized society. Maybe my definition for civilization is different or the work is not civilized what you think?
