Seventy years ago, the US became the first and only nation to use a nuclear weapon in war
At least nine countries now have nuclear weapons, but the United States remains the only country that actually used an atomic bomb against an enemy. On Aug. 6, 1945, the US dropped an atom bomb on the Japanese city of Hiroshima; three days later a second bomb was dropped on Nagasaki. Six days later, on Aug. 15, Japan announced it would surrender, effectively ending World War II. But the decision to use this devastating weapon remains controversial.

Analyzing the Arguments

Dropping the atomic bomb was necessary to end the war with Japan at the earliest possible moment. By the early summer of 1945, Japanese leaders knew they couldn’t win. But they fought on in hopes of securing better surrender terms.

President Harry S. Truman recognized that he had several options to convince Japan to end the war: 1) intensifying the already-heavy bombing of Japanese cities; 2) waiting for the Soviet Union, an ally in defeating Germany, to join the war against Japan; 3) telling Japan that the US would allow Emperor Hirohito to remain on his throne after the war; and 4) invading Japan with ground troops.

But there was no guarantee that any of these options, or a combination of them, would force the Japanese to surrender quickly, and each one posed serious military, political, and diplomatic risks. Invading Japan may have been the least uncertain militarily, but it carried the highest price: More than 100,000 Americans had already died fighting the Japanese in the Pacific, and an invasion was certain to be very costly in American lives. And for Truman, any number of American lives that could be saved by using the bomb would be well worth it.

When the atomic bomb became available in July 1945, it was the most promising way to end the war as soon as possible and without the drawbacks of the other options.

The attacks on Hiroshima and Nagasaki persuaded Emperor Hirohito, who had wavered for weeks, that the war must end immediately. Combined with the Soviet Union’s entry into conflict after Hiroshima, the atom bombs brought about Japan’s surrender within a few days.

The bomb was necessary to accomplish Truman’s primary objectives of forcing a prompt Japanese surrender and saving American lives, perhaps many thousands of them.

Author, Prompt and Utter Destruction: Truman and the Use of Atomic Bombs Against Japan
When General Dwight D. Eisenhower, then the Supreme Allied Commander, was informed by the US Secretary of War that the atomic bomb was going to be used, he later recalled saying it was unnecessary because Japan was already largely defeated. Eisenhower said the bomb was “no longer mandatory as a measure to save American lives.” After the war, as president of the United States (1953-1961), he even stated publicly: “It wasn’t necessary to hit them with that awful thing.”

Before the bomb was used, American intelligence officials believed the war would likely end when two things happened: When the US let Japan know the emperor could remain as a figurehead, and when the Soviet army attacked. The US did tell Japan the emperor could remain on his throne as part of a surrender, and the Soviets declared war, as agreed, on August 8.

But American officials chose not to test whether this intelligence was correct. For logistical reasons, an invasion of Japan couldn’t begin for another three months, so the US could have waited to see if Japan would surrender before dropping the atomic bombs. Instead, Hiroshima was bombed on August 6, and Nagasaki on August 9.

Hiroshima was of only marginal value as a military target, which is why it hadn’t already been a target of conventional bombings, and it was full of women, children, and old people, since most of the men had left to fight the war.

Many top World War II military leaders are on record agreeing with Eisenhower that using the atomic bomb was unnecessary. Some felt it was deeply immoral. Even Admiral Leahy, President Truman’s chief of staff, later called the bomb a “barbarous weapon” that should not have been used. Leahy wrote, “The Japanese were already defeated and ready to surrender...In being the first to use it, we...adopted an ethical standard common to the barbarians of the Dark Ages.”

Author, The Decision to Use the Atomic Bomb

My Grandfather, George McDermott and Great uncle Jack McDermott both

served during WWII. I interviewed my Great uncle Jack to find out about his and my

grandfathers experiences during the war. What follows is some of the information I

received about these brothers’ experiences during the war.

Q.: What were your jobs during the war?

Jack McDermott: Your Grandfather George was a student at Loyola University’s

Med School. When he graduated he had to give service because the government

controlled Loyola during the war. He went to Hawaii first then to Guadalcanal

where he served as a surgeon. I enlisted in 1945. I wanted to help with the defeat

of Japan and Hitler. I did my basic training at Camp Robinson in Arkansas. We

went to Baltimore next and were reading to be sent to Europe when plans were

changed. We went to Seattle instead. I then went on a troop carrier headed to

Japan. I was in the 27th infantry division. I was a rifleman and the Assistant pay

chief of the 1st cavalry. I was in Honshu Japan in 1945-46. We wore a yellow

patch which represented the 27th cavalry.

Q.: What took place during your time there?

J.M.: The Japanese had an elaborate tunnel system and caves that they used. We

had to bomb them out. They would not give up. We were losing 4-5,000 men a

week on the beaches until the A bombs were dropped. The A bombs saved

American lives because the Japanese would not have given up. The U.S.

bombings burned out Japanese towns and rivers but were necessary to defeat the

Japanese and to save American lives.
Q.: Where were you when the Bombs were dropped?

J.M.: I was at sea when the bombs were dropped on Nagasaki and Hiroshima in

August of ’45. Emperor Hirohito gave up after the second bomb was dropped. A

treaty was signed on September 2, 1945. After the treaty was signed, half of my

division flew in to the south of Tokyo and then went on to Tokyo. The

paratroopers went in North of Tokyo. My first 60 days were spent in Niigata,

Japan which we took over.
