Why Did Harry S. Truman Dropped The Atomic Bomb?

Harry S. Truman had to make some of the most difficult choices that any president has ever had to make. He was president from April 12, 1945 to January 20, 1953, he took over just before World War 2 ended, went through the Korean war, and went through part of the Cold war. When Truman took office Franklin D. Roosevelt died about three months after and close to the same time he had to make the choice of dropping the atomic bombs on Japan to end the war. Which to date are the only atomic bombs used in war. Truman had one of the hardest presidencies out of all of them because of all the decisions he had to make that have not been topped.
Truman's political career started in the 1920’s when he ran for County-Judge in Jackson County. When he ran
for reelection, he lost, but in 1926 he tried again and was elected presiding Judge, he held that title till he ran for senator. He was elected part of the senate in 1934, he helped allocate tax money for F.D.R.’s “New Deal Projects”. He ran for reelection and shortly before that Thomas Pendergast was convicted of tax evasion and associated with voter fraud. Because Roosevelt had been associated with him, so many people thought he would’ve lost because of the association but he pulled through using his good reputation. Truman kept rising in the ranks of politics and in 1944 F.D.R choose Truman to be his vice president candidate. They won the election and Truman took the oath of office on January 20, 1945.
