Why did Truman decide to drop the atomic bomb on Hiroshima?
Answer in a paragraph please

His decision was merely military strategy. When he became president, he had discovered the Manhattan Project which was a hidden scientific project in creating an atomic bomb and when it was successfully tested, he issued the Potsdam Declaration in which he demanded the Japanese government to surrender. He warned them (indirectly hinting the atomic bomb). When he had received recieved no reply 11 days later, he took it in his initiative to drop the atomic bomb called “Little boy”. This resulted in destruction of an estimate of eighty thousand deaths from its impact, then thousands later due to the radiation.
