Sadako was only 2 years old when the first atomic weapon was dropped on Horishima, Japan on August 6, 1945.
10 years later in November 1954 Sadako was diagnosed with lukemia from the atomic weapon. She was given 1 year to live. Shei was moved from home to Red Cross Hospital Horishma. She met a girl who also had lukiemia. Her name was Chizuko. They became close and chizoku came up with an idea to make sure Sadako didn't give up hope. Chizoku reminded sadako of the story of the one thousand paper cranes and how if you make one thousand the gods will grant you a wish. Sadako began her journey of making the thousand paper cranes.
In octber 25, 1955 Sadako passed away and sadly only got to make 644 but after her death her friends from school and family helped to make the one thousand paper cranes. There were books and movies made about her and her faith and hope. There was a statue made for her located in horishma Japan holding a golden paper crane. This beautiful girl changed the whole world by making people realise never to use the atomic weapon again.
I think that it was probably better that the atomic weapon was used then in 1945 because if they had of waited and maybe used it now they may of made it even more powerful. There probable would have been even more damage, more injuries and more death. It was also better because it taught people that it was an extremely dangerous weapon and not to use it again.
