World War II killed more people, involved more nations, and cost more money than any other war in history. Altogether, 70 million people served in the armed forces during thOverview of World War II
World War II killed more people, involved more nations, and cost more money than any other war in history. Altogether, 70 million people served in the armed forces during the war, and 17 million combatants died. Civilian deaths were ever greater. At least 19 million Soviet civilians, 10 million Chinese, and 6 million European Jews lost their lives during the war.
World War II was truly a global war. Some 70 nations took part in the conflict, and fighting took place on the continents of Africa, Asia, and Europe, as well as on the high seas. Entire societies participated as soldiers or as war workers, while others were persecuted as victims of occupation and mass murder.
World War II cost the United States a million causalities and nearly 400,000 deaths. In both domestic and foreign affairs, its consequences were far-reaching. It ended the Depression, brought millions of married women into the workforce, initiated sweeping changes in the lives of the nation's minority groups, and dramatically expanded government's presence in American life.
The War at Home & Abroad
On September 1, 1939, World War II started when Germany invaded Poland. By November 1942, the Axis powers controlled territory from Norway to North Africa and from France to the Soviet Union. After defeating the Axis in North Africa in May 1941, the United States and its Allies invaded Sicily in July 1943 and forced Italy to surrender in September. On D-Day, June 6, 1944, the Allies landed in Northern France. In December, a German counteroffensive (the Battle of the Bulge) failed. Germany surrendered in May 1945.
The United States entered the war following a surprise attack by Japan on the U.S. Pacific fleet in Hawaii. The United States and its Allies halted Japanese expansion at the Battle of Midway in June 1942 and in other campaigns in the South Pacific. From 1943 to August 1945, the Allies hopped from island to island across the Central Pacific and also battled the Japanese in China, Burma, and India. Japan agreed to surrender on August 14, 1945 after the United States dropped the first atomic bombs on the Japanese cities of Hiroshima and Nagasaki.
Consequences:
1. The war ended Depression unemployment and dramatically expanded government's presence in American life. It led the federal government to create a War Production Board to oversee conversion to a wartime economy and the Office of Price Administration to set prices on many items and to supervise a rationing system.
2. During the war, African Americans, women, and Mexican Americans founded new opportunities in industry. But Japanese Americans living on the Pacific coast were relocated from their homes and placed in internment camps.
The Dawn of the Atomic Age
In 1939, Albert Einstein wrote a letter to President Roosevelt, warning him that the Nazis might be able to build an atomic bomb. On December 2, 1942, Enrico Fermi, an Italian refugee, produced the first self-sustained, controlled nuclear chain reaction in Chicago.
To ensure that the United States developed a bomb before Nazi Germany did, the federal government started the secret $2 billion Manhattan Project. On July 16, 1945, in the New Mexico desert near Alamogordo, the Manhattan Project's scientists exploded the first atomic bomb.
It was during the Potsdam negotiations that President Harry Truman learned that American scientists had tested the first atomic bomb. On August 6, 1945, the Enola Gay, a B-29 Superfortress, released an atomic bomb over Hiroshima, Japan. Between 80,000 and 140,000 people were killed or fatally wounded. Three days later, a second bomb fell on Nagasaki. About 35,000 people were killed. The following day Japan sued for peace.
President Truman's defenders argued that the bombs ended the war quickly, avoiding the necessity of a costly invasion and the probable loss of tens of thousands of American lives and hundreds of thousands of Japanese lives. His critics argued that the war might have ended even without the atomic bombings. They maintained that the Japanese economy would have been strangled by a continued naval blockade, and that Japan could have been forced to surrender by conventional firebombing or by a demonstration of the atomic bomb's power.
The unleashing of nuclear power during World War II generated hope of a cheap and abundant source of energy, but it also produced anxiety among large numbers of people in the United States and around the world.... More
Description Operation Strangle was a series of air interdiction operations during the Italian Campaign of World War II by the United States Fifteenth and Twelfth Air Forces to interdict German supply routes in ItOperation Strangle was a series of air interdiction operations during the Italian Campaign of World War II by the United States Fifteenth and Twelfth Air Forces to interdict German supply routes in Italy north of Rome from March 24, 1943, until the fall of Rome in spring 1944. Its aim was to prevent essential supplies from reaching German forces in central Italy and compel a German withdrawal. The strategic goal of the air assault was to eliminate or greatly reduce the need for a ground assault on the region. Although the initial goal of forcing the enemy to withdraw was not achieved, the air interdiction of Operation Strangle played a major role in the success of the subsequent ground assault Operation Diadem.
Two principal interdiction lines were maintained across the narrow boot of Italy. This meant that no through trains were able to run from the Po Valley to the front line, and that south of Florence substantially all supplies had to be moved by truck. The operation employed medium bombers and fighter bombers over a 150-square-mile (390 km2) area from Rome to Pisa and from Pescara to Rimini.... More

By that time Allied air power had begun the attack on Sicily by bombing defenses and airfields. The invasion itself got under way on the night of 9/10 July with airborne landings that were followed the next day by an amphibious assault. The enemy offered strong resistance, but the Allies had superiority in the air and soon had planes operating from Sicilian bases to support Montgomery’s Eighth Army and Patton’s Seventh.
Interdictory operations against communications in Italy and between Italy and Sicily convinced the enemy that it would be impossible to move strong reinforcements. By 17 August 1943 the Allies were in possession of the island, but they had not been able to prevent a German evacuation across the Strait of Messina. ... More

But the drive broke down short of the goal. In February 1943, after Rommel had been driven into Tunisia, the Axis took the offensive and pushed through Kasserine Pass before being stopped. With Ninth and Twelfth Air Forces in the battle, the Allies drove the enemy back into a pocket around Bizerte and Tunis, where Axis forces surrendered in May. Thus Tunisia became available for launching an attack on Sicily as a preliminary to an assault on Italy. ... More

Two independent, coordinate commands, one in the Southwest PaciThe plan of the Pacific subseries was determined by the geography, strategy, and the military organization of a theater largely oceanic. Two independent, coordinate commands, one in the Southwest Pacific under General of the Army Douglas MacArthur and the other in the Central, South, and North Pacific (Pacific Ocean Areas) under Fleet Admiral Chester W. Nimitz, were created early in the war. Except in the South and Southwest Pacific, each conducted its own operations with its own ground, air, and naval forces in widely separated areas. These operations required at first only a relatively small number of troops whose efforts often yielded strategic gains which cannot be measured by the size of the forces involved. Indeed, the nature of the objectivesùsmall islands, coral atolls, and jungle-bound harbors and airstrips, made the employment of large ground forces impossible and highlighted the importance of air and naval operations. Thus, until 1945, the war in the Pacific progressed by a double series of amphibious operations each of which fitted into a strategic pattern developed in Washington.
21 Named Campaigns were recognized in the Asiatic Pacific Theater with Battle Streamers and Asiatic Pacific Campaign Medals. ... More
Description (Air Offensive Campaign Japan 17 April 1942 to 2 September 1945) The United States strategic bombing of Japan took place between 1942 and 1945. In the last seven months of the campaign, a change to fi(Air Offensive Campaign Japan 17 April 1942 to 2 September 1945) The United States strategic bombing of Japan took place between 1942 and 1945. In the last seven months of the campaign, a change to firebombing resulted in great destruction of 67 Japanese cities, as many as 500,000 Japanese deaths and some 5 million more made homeless. Emperor Hirohito's viewing of the destroyed areas of Tokyo in March 1945 is said to have been the beginning of his personal involvement in the peace process, culminating in Japan's surrender five months later.
The first U.S. raid on the Japanese main island was the Doolittle Raid of 18 April 1942, when sixteen B-25 Mitchells were launched from the USS Hornet (CV-8) to attack targets including Yokohama and Tokyo and then fly on to airfields in China. The raids were military pinpricks but a significant propaganda victory. Because they were launched prematurely, none of the aircraft had enough fuel to reach their designated landing sites, and so either crashed or ditched (except for one aircraft, which landed in the Soviet Union, where the crew was interned). Two crews were captured by the Japanese.
The key development for the bombing of Japan was the B-29 Superfortress, which had an operational range of 1,500 miles (2,400 km); almost 90% of the bombs (147,000 tons) dropped on the home islands of Japan were delivered by this bomber. The first raid by B-29s on Japan was on 15 June 1944, from China. The B-29s took off from Chengdu, over 1,500 miles away. This raid was also not particularly effective: only forty-seven of the sixty-eight bombers hit the target area; four aborted with mechanical problems, four crashed, six jettisoned their bombs because of mechanical difficulties, and others bombed secondary targets or targets of opportunity. Only one B–29 was lost to enemy aircraft. The first raid from east of Japan was on 24 November 1944, when 88 aircraft bombed Tokyo. The bombs were dropped from around 30,000 feet (10,000 m) and it is estimated that only around 10% hit their targets.
Raids of Japan from mainland China, called Operation Matterhorn, were carried out by the Twentieth Air Force under XX Bomber Command. Initially the commanding officer of the Twentieth Air Force was Hap Arnold, and later Curtis LeMay. Bombing from Japan from China was never a satisfactory arrangement because not only were the Chinese airbases difficult to supply—materiel being sent by air from India over "the Hump"—but the B-29s operating from them could only reach Japan if they traded some of their bomb load for extra fuel in tanks in the bomb-bays. When Admiral Chester Nimitz's island-hopping campaign captured Pacific islands close enough to Japan to be within the B-29's range, the Twentieth Air Force was assigned to XXI Bomber Command, which organized a much more effective bombing campaign of the Japanese home islands. Based in the Marianas (Guam and Tinian in particular), the B-29s were able to carry their full bomb loads and were supplied by cargo ships and tankers.
Conventional bombs from B-29s destroyed over 40% of the urban area in Japan's six greatest industrial cities
Unlike all other forces in theater, the USAAF Bomber Commands did not report to the commanders of the theaters but directly to the Joint Chiefs of Staff. In July 1945, they were placed under the U.S. Strategic Air Forces in the Pacific, which was commanded by General Carl Spaatz.
As in Europe, the United States Army Air Forces (USAAF) tried daylight precision bombing. However, it proved to be impossible due to the weather around Japan, "during the best month for bombing in Japan, visual bombing was possible for [just] seven days. The worst had only one good day." Further, bombs dropped from a great height were tossed about by high winds.
General LeMay, commander of XXI Bomber Command, instead switched to mass firebombing night attacks from altitudes of around 7,000 feet (2,100 m) on the major conurbations. "He looked up the size of the large Japanese cities in the World Almanac and picked his targets accordingly." Priority targets were Tokyo, Nagoya, Osaka, and Kobe. Despite limited early success, particularly against Nagoya, LeMay was determined to use such bombing tactics against the vulnerable Japanese cities. Attacks on strategic targets also continued in lower-level daylight raids.
The first successful firebombing raid was on Kobe on 3 February 1945, and following its relative success the USAAF continued the tactic. Nearly half of the principal factories of the city were damaged, and production was reduced by more than half at one of the port's two shipyards.
Much of the armor and defensive weaponry of the bombers was removed to allow increased bomb loads; Japanese air defense in terms of night-fighters and anti-aircraft guns was so feeble it was hardly a risk. The first raid of this type on Tokyo was on the night of 23–24 February when 174 B-29s destroyed around one square mile (3 km²) of the city. Following on that success, as Operation Meetinghouse, 334 B-29s raided on the night of 9–10 March, dropping around 1,700 tons of bombs. Around 16 square miles (41 km²) of the city was destroyed and over 100,000 people are estimated to have died in the fire storm. The destruction and damage was at its worst in the city sections east of the Imperial Palace. It was the most destructive conventional raid, and the deadliest single bombing raid of any kind in terms of lives lost, in all of military aviation history. The city was made primarily of wood and paper, and Japanese firefighting methods were not up to the challenge. The fires burned out of control, boiling canal water and causing entire blocks of buildings to spontaneously combust from the heat. The effects of the Tokyo firebombing proved the fears expressed by Admiral Yamamoto in 1939: "Japanese cities, being made of wood and paper, would burn very easily. The Army talks big, but if war came and there were large-scale air raids, there's no telling what would happen."[179]
In the following two weeks, there were almost 1,600 further sorties against the four cities, destroying 31 square miles (80 km²) in total at a cost of 22 aircraft. By June, over forty percent of the urban area of Japan's largest six cities (Tokyo, Nagoya, Kobe, Osaka, Yokohama, and Kawasaki) was devastated. LeMay's fleet of nearly 600 bombers destroyed tens of smaller cities and manufacturing centres in the following weeks and months.
Leaflets were dropped over cities before they were bombed, warning the inhabitants and urging them to escape the city. Though many, even within the Air Force, viewed this as a form of psychological warfare, a significant element in the decision to produce and drop them was the desire to assuage American anxieties about the extent of the destruction created by this new war tactic. Warning leaflets were also dropped on cities not in fact targeted, to create uncertainty and absenteeism. ... More
