Preferable to invasion

There were those who considered that the atomic bomb should never have been used at all. I cannot associate myself with such ideas… I am surprised that very worthy people—but people who in most cases had no intention of proceeding to the Japanese front themselves—should adopt a position that rather than throw this bomb we should have sacrificed a million American and a quarter of a million British lives… |

Winston Churchill, leader of the Opposition, in a speech to the British House of Commons, August 1945[6]
A map outlining the Japanese and U.S. (but not other Allied) ground forces scheduled to take part in the ground battle for Japan. Two landings were planned: (1) Olympic—the invasion of the southern island, KyÅ«shÅ«, (2) Coronet—the invasion of the main island, HonshÅ«.
March 1946's Operation Coronet was planned to take Tokyo with a landing of 25 divisions, compared to D-Day's 12 Divisions.
Those who argue in favor of the decision to drop the atom bombs argue that massive casualties on both sides would have occurred in Operation Downfall, the planned invasion of Japan.[7]
The U.S. side anticipated losing many soldiers in the planned invasion of Japan, although the actual number of expected fatalities and wounded is subject to some debate. U.S. President Truman stated after the war that he had been advised that U.S. casualties could range from 250,000 to one million men.[8] In a study done by the Joint Chiefs of Staff in April 1945, the figures of 7.45 casualties per 1,000 man-days and 1.78 fatalities per 1,000 man-days were developed. This implied that the two planned campaigns to conquer Japan would cost 1.6 million U.S. casualties, including 370,000 dead.[9]
In addition, millions of Japanese military and civilian casualties were expected.[10] An Air Force Association history says, "Millions of women, old men, and boys and girls had been trained to resist by such means as attacking with bamboo spears and strapping explosives to their bodies and throwing themselves under advancing tanks,"[11] and also that "[t]he Japanese cabinet had approved a measure extending the draft to include men from ages fifteen to sixty and women from seventeen to forty-five (an additional 28 million people).[12]
Supporters also point to an order given by the Japanese War Ministry on 1 August 1944, ordering the disposal and execution of all Allied prisoners of war, numbering over 100,000, if an invasion of the Japanese mainland took place.[13]
Nearly 500,000 Purple Heart medals were manufactured in anticipation of the casualties resulting from the invasion of Japan. To the present date, all the American military casualties of the sixty years following the end of World War II—including the Korean and Vietnam Wars—have not exceeded that number. In 2003, there were still 120,000 of these Purple Heart medals in stock.[14] There are so many in surplus that combat units in Iraq andAfghanistan are able to keep Purple Hearts on-hand for immediate award to wounded soldiers on the field.[14]
[edit]Speedy end of war saved lives
Supporters of the bombing also argue that waiting for the Japanese to surrender was not a cost-free option. "For China alone, depending upon what number one chooses for overall Chinese casualties, in each of the ninety-seven months between July 1937 and August 1945, somewhere between 100,000 and 200,000 persons perished, the vast majority of them noncombatants. For the other Asian states alone, the average probably ranged in the tens of thousands per month, but the actual numbers were almost certainly greater in 1945, notably due to the mass death in a famine in Vietnam. Newman concluded that each month that the war continued in 1945 would have produced the deaths of 'upwards of 250,000 people, mostly Asian but some Westerners.'"[15][16]
The end of the war also liberated millions of laborers working in harsh conditions under a forced mobilization. In the Dutch East Indies, there was a "forced mobilization of some 4 million—although some estimates are as high as 10 million—romusha (manual laborers)...About 270,000 romusha were sent to the Outer Islands and Japanese-held territories in Southeast Asia, where they joined other Asians in performing wartime construction projects. At the end of the war, only 52,000 were repatriated to Java."[17][clarification needed]
The firebombing of Tokyo had killed well over 100,000 people in Japan since February 1945, directly and indirectly. Intensive conventional bombing would have continued or increased prior to an invasion. The submarine blockade and the United States Army Air Forces's mining operation, Operation Starvation, had effectively cut off Japan's imports. A complementary operation against Japan's railways was about to begin, isolating the cities of southern Honshū from the food grown elsewhere in the Home Islands. "Immediately after the defeat, some estimated that 10 million people were likely to starve to death," noted historian Daikichi Irokawa.[18] Meanwhile, fighting continued in The Philippines, New Guinea and Borneo, and offensives were scheduled for September in southern China and Malaya. The Soviet invasion of Manchuria, had in the week before the surrender caused over 80,000 deaths.[19]
In September 1945, nuclear physicist Karl T. Compton, who himself took part in the Manhattan Project, visited MacArthur's headquarters in Tokyo, and following his visit wrote a defensive article, in which he summarized his conclusions as follows: "If the atomic bomb had not been used, evidence like that I have cited points to the practical certainty that there would have been many more months of death and destruction on an enormous scale".[20]
Philippine justice Delfin Jaranilla, member of the Tokyo tribunal, wrote in his judgment:
"If a means is justified by an end, the use of the atomic bomb was justified for it brought Japan to her knees and ended the horrible war. If the war had gone longer, without the use of the atomic bomb, how many thousands and thousands of helpless men, women and children would have needlessly died and suffer ...?"[21]
