Would the Us Consider Using the a Bomb Again

Always since America dropped a 2nd atomic bomb on Nagasaki, Japan on Baronial nine, 1945, the question has persisted: Was that magnitude of decease and destruction really needed to end World War II?

American leadership plainly thought so. A few days earlier, merely 16 hours after the U.S. B-29 bomber Enola Gay shocked the globe by dropping the kickoff A-bomb known as "Little Boy" on the Japanese city of Hiroshima, the White House issued a statement from President Harry Due south. Truman.

In improver to introducing the world to the previously top-secret atomic enquiry program known as the Manhattan Project, Truman doubled down on the threat that nuclear weapons posed to Japan, America's only remaining adversary in the state of war. If the Japanese did not accept the terms of unconditional surrender drafted by Allied leaders in the Potsdam Declaration, Truman wrote, "they may await a rain of ruin from the air, the like of which has never been seen on this earth."

But even as Truman issued his statement, a second atomic attack was already in the works. According to an gild drafted in belatedly July by Lt. Gen. Leslie Groves of the U.S. Army Corps of Engineers, director of the Manhattan Project, the president had authorized the dropping of additional bombs on the Japanese cities of Kokura (present-solar day Kitakyushu), Niigata and Nagasaki every bit soon as the weather permitted.

Nagasaki Wasn't the Original Target

Early on the morn of August nine, 1945, the B-29 known as Bockscar took off from Tinian Island in the western Pacific Ocean, conveying the nearly x,000-pound plutonium-based bomb known as "Fatty Man" toward Kokura, home to a large Japanese arsenal. Finding Kokura obscured by cloud cover, the Bockscar'south crew decided to caput to their secondary target, Nagasaki.

"Fat Man," which detonated at 11:02 local time at an altitude of i,650 feet, killed about half as many people in Nagasaki as the uranium-based "Fiddling Male child" had in Hiroshima iii days earlier—despite a forcefulness estimated at 21 kilotons, or 40 percent greater. Still, the consequence was devastating: close to xl,000 people were killed instantly, and a third of the city was destroyed.

"This second sit-in of the power of the atomic bomb apparently threw Tokyo into a panic, for the next morning brought the outset indication that the Japanese Empire was ready to surrender," Truman later wrote in his memoirs. On August fifteen, Emperor Hirohito announced Nihon's unconditional surrender, bringing World War II to a close.

Official A-Bomb Justification: Save United states of america Lives

According to Truman and others in his administration, the use of the atomic bomb was intended to cut the war in the Pacific short, avoiding a U.Due south. invasion of Japan and saving hundreds of thousands of American lives.

Curl to Keep

In early 1947, when urged to answer to growing criticism over the utilize of the atomic bomb, Secretary of State of war Henry Stimson wrote in Harper's Magazine that by July 1945 in that location had been no sign of "whatsoever weakening in the Japanese determination to fight rather than accept unconditional give up." Meanwhile, the U.S. was planning to ramp up its body of water and air occludent of Nihon, increment strategic air bombings and launch an invasion of the Japanese dwelling island that November.

"We estimated that if we should exist forced to carry this programme to its conclusion, the major fighting would non end until the latter office of 1946, at the earliest," Stimson wrote. "I was informed that such operations might exist expected to cost over a million casualties, to American forces solitary."

The Other Reason? Go the Soviet Union's Attention

Despite the arguments of Stimson and others, historians have long debated whether the United States was justified in using the atomic bomb in Japan at all—let alone twice. Various war machine and noncombatant officials have said publicly that the bombings weren't a military necessity. Japanese leaders knew they were beaten even before Hiroshima, equally Secretarial assistant of State James F. Byrnes argued on August 29, 1945, and had reached out to the Soviets to run into if they would mediate in possible peace negotiations. Fifty-fifty the famously hawkish General Curtis LeMay told the press in September 1945 that "the atomic bomb had nothing to practice with the end of the war at all."

Statements similar these have led historians such every bit Gar Alperovitz, author of The Decision to Use the Atomic Flop, to suggest that the flop's true purpose was to become the upper hand with the Soviet Marriage. According to this line of thinking, the U.s.a. deployed the plutonium flop on Nagasaki to make clear the strength of its nuclear arsenal, ensuring the nation's supremacy in the global power hierarchy.

Others accept argued that both attacks were simply an experiment, to see how well the two types of atomic weapons adult by the Manhattan Project worked. Admiral William "Bull" Halsey, commander of the U.S. Navy'southward 3rd Armada, claimed in 1946 that the first atomic bomb was "an unnecessary experiment…[the scientists] had this toy and they wanted to try information technology out, and so they dropped it."

Was a second nuclear attack necessary to force Japan's surrender? The world may never know. For his role, Truman doesn't seem to have wavered in his conviction that the attacks were justified—though he ruled out future flop attacks without his limited order the 24-hour interval after Nagasaki. "It was a terrible decision. But I made it," the 33rd president later wrote to his sister, Mary. "I made it to save 250,000 boys from the United States, and I'd make it once again under similar circumstances."
