several offensives by both sides, the war between China and Japan was stalemated by 1940. To increase pressure on China by blocking supply routes, and to better position Japanese forces in the event of a war with the Western powers, Japan invaded and
occupied northern Indochina in September 1940.

, but negotiations for additional access to their resources ended in failure in June 1941. In July 1941 Japan sent troops to southern Indochina, thus threatening British and Dutch possessions in the Far East. The United States, the United Kingdom, and other Western governments reacted to this move with a freeze on Japanese assets and a total oil embargo. At the same time, Japan was
planning an invasion of the Soviet Far East, intending to capitalise off the German invasion in the west, but abandoned the operation after the sanctions.
Since early 1941 the United States and Japan had been engaged in negotiations in an attempt to improve their strained relations and end the war in China. During these negotiations, Japan advanced a number of proposals which were dismissed by the Americans as inadequate.
At the same time the United States, the United Kingdom, and the Netherlands engaged in secret discussions for the joint defence of their territories, in the event of a Japanese attack against any of them.

to the Emperor. On 5 November, Hirohito approved in imperial conference the operations plan for the war. On 20 November, the new government presented an interim proposal as its final offer. It called for the end of American aid to China and for lifting the embargo on the supply of oil and other resources to Japan. In exchange, Japan promised not to launch any attacks in Southeast Asia and to withdraw its forces from southern Indochina. The American counter-proposal of 26 November required that Japan evacuate all of China without conditions and conclude non-aggression pacts with all Pacific powers. That meant Japan was essentially forced to choose between abandoning its ambitions in China, or seizing the natural resources it needed in the Dutch East Indies by force; the Japanese military did not consider the former an option, and many officers considered the oil embargo an unspoken declaration of war.
Japan planned to seize European colonies in Asia to create a large defensive perimeter stretching into the Central Pacific. The Japanese would then be free to exploit the resources of Southeast Asia while exhausting the over-stretched Allies by fighting a defensive war. To prevent American intervention while securing the perimeter, it was further planned to neutralise the

to pursue. All agreed that
defeating Germany was the primary objective. The Americans favoured a straightforward,
large-scale attack on Germany through France. The Soviets were also demanding a second front. The British, on the other hand, argued that military operations should target peripheral areas to wear out German strength, leading to increasing demoralisation, and bolster resistance forces. Germany itself would be subject to a heavy bombing campaign. An offensive against Germany would then be launched primarily by Allied armour without using large-scale armies. Eventually, the British persuaded the Americans that a landing in France was infeasible in 1942 and they should instead focus on driving the Axis out of North Africa.

In August 1942, the Allies succeeded in repelling a
second attack against El Alamein and, at a high cost, managed to
deliver desperately needed supplies to the besieged Malta. A few months later, the Allies
commenced an attack of their own in Egypt, dislodging the Axis forces and beginning a drive west across Libya. This attack was followed up shortly after by
Anglo-American landings in French North Africa, which resulted in the region joining the Allies. Hitler responded to the French colony's defection by ordering the
occupation of Vichy France; although Vichy forces did not resist this violation of the armistice, they managed to
scuttle their fleet to prevent its capture by German forces. The Axis forces in Africa withdrew into

After the Guadalcanal Campaign, the Allies initiated several operations against Japan in the Pacific. In May 1943, Canadian and US forces were sent to
eliminate Japanese forces from the Aleutians. Soon after, the United States, with support from Australia, New Zealand and Pacific Islander forces, began major ground, sea and air operations to
isolate Rabaul by capturing surrounding islands, and
breach the Japanese Central Pacific perimeter at the Gilbert and Marshall Islands. By the end of March 1944, the Allies had completed both of these objectives and had also
neutralised the major Japanese base at Truk in the

In the Soviet Union, both the Germans and the Soviets spent the spring and early summer of 1943 preparing for large offensives in central Russia. On 5 July 1943, Germany
attacked Soviet forces around the Kursk Bulge. Within a week, German forces had exhausted themselves against the Soviets' deeply echeloned and well-constructed defences, and for the first time in the war, Hitler cancelled an operation before it had achieved tactical or operational success. This decision was partially affected by the Western Allies'

In Germany, the western and eastern occupation zones controlled by the Western Allies and the Soviet Union officially ended in 1949, with the respective zones becoming separate countries, West Germany and East Germany. However, in Austria occupation continued until 1955, when a joint settlement between the Western Allies and the Soviet Union permitted the reunification of Austria as a neutral democratic state, officially non-aligned with any political bloc (although in practice having better relations with the Western Allies). A denazification program in Germany led to the prosecution of Nazi war criminals in the Nuremberg trials and the removal of ex-Nazis from power, although this policy moved towards amnesty and re-integration of ex-Nazis into West German society.

In China, nationalist and communist forces resumed Chinese Civil War, the civil war in June 1946. Communist forces were victorious and established the People's Republic of China on the mainland, while nationalist forces retreated to Taiwan in 1949.
[.] In the Middle East, the Arab rejection of the United Nations Partition Plan for Palestine and the creation of Israel marked the escalation of the Arab–Israeli conflict. While European powers attempted to retain some or all of their colonial empires, their losses of prestige and resources during the war rendered this unsuccessful, leading to Decolonization, decolonisation.

The global economy suffered heavily from the war, although participating nations were affected differently. The United States emerged much richer than any other nation, leading to a Post–World War II baby boom, baby boom, and by 1950 its gross domestic product per person was much higher than that of any of the other powers, and it dominated the world economy. The UK and US pursued a policy of Allied plans for German industry after World War II, industrial disarmament in Western Germany in the years 1945–1948.
[.] Because of international trade interdependencies this led to European economic stagnation and delayed European recovery for several years.
[.]
At the Bretton Woods Conference in July 1944, the Allied nations drew up an economic framework for the post-war world. The agreement created the International Monetary Fund (IMF) and the International Bank for Reconstruction and Development (IBRD). The Bretton Woods system lasted until 1973. Recovery began with the mid-1948 Deutsche Mark, currency reform in Western Germany, and was sped up by the liberalisation of European economic policy that the Marshall Plan (1948–1951) both directly and indirectly caused.
[.] The post-1948 West German recovery has been called the Wirtschaftswunder#West Germany, German economic miracle. Italy also experienced an Italian economic miracle, economic boom and the Trente Glorieuses, French economy rebounded. By contrast, the United Kingdom was in a state of economic ruin, and although receiving a quarter of the total Marshall Plan assistance, more than any other European country, it continued in relative economic decline for decades.
The Soviet Union, despite enormous human and material losses, also experienced rapid increase in production in the immediate post-war era.
[.] Japan recovered much later. China returned to its pre-war industrial production by 1952.
Impact
Casualties and war crimes
![World War II Casualties](https://upload.wikimedia.org/wikipedia/commons/d/d1/World_War_II_Casualties.svg)
Estimates for the total number of casualties in the war vary, because many deaths went unrecorded. Most suggest that some 60 million people died in the war, including about Battle casualties of World War II, 20 million military personnel and 40 million civilians.
Many of the civilians died because of deliberate

The Soviet Union alone lost around 27 million people during the war, including 8.7 million military and 19 million civilian deaths.
[.] A quarter of the total people in the Soviet Union were wounded or killed. Germany sustained 5.3 million military losses, mostly on the Eastern Front and during the final battles in Germany.

An estimated 11 to 17 million

. Concurrently, Bosniaks, Muslims and Croats were Chetnik war crimes in World War II, persecuted and killed by Serb nationalist Chetniks, with an estimated 50,000-68,000 victims (of which 41,000 were civilians).
Also, more than 100,000 Poles were massacred by the Ukrainian Insurgent Army in the Massacres of Poles in Volhynia and Eastern Galicia, Volhynia massacres, between 1943 and 1945. At the same time, about 10,000–15,000 Ukrainians were killed by the Polish Home Army and other Polish units, in reprisal attacks.
![Nanking bodies 1937](https://upload.wikimedia.org/wikipedia/commons/7/72/Nanking_bodies_1937.jpg)
In Asia and the Pacific, the number of people killed by Japanese troops remains contested. According to R.J. Rummel, the Japanese killed between 3million and more than 10 million people, with the most probable case of almost 6,000,000 people. According to the British historian M. R. D. Foot, civilian deaths are between 10 million and 20 million, whereas Chinese military casualties (killed and wounded) are estimated to be over five million. Other estimates say that up to 30 million people, most of them civilians, were killed. The most infamous Japanese atrocity was the Nanking Massacre, in which fifty to three hundred thousand Chinese civilians were raped and murdered. Mitsuyoshi Himeta reported that 2.7 million casualties occurred during the ''Three Alls Policy, Sankō Sakusen''. General Yasuji Okamura implemented the policy in Heipei and Shantung.
Axis forces employed Biological warfare, biological and Chemical warfare, chemical weapons. The Imperial Japanese Army used a variety of such weapons during its Second Sino-Japanese War, invasion and occupation of China (''see Unit 731'') and in Battles of Khalkhin Gol, early conflicts against the Soviets.

[''«....Già nello scatenarsi della prima ondata di cieca violenza in quelle terre, nell'autunno del 1943, si intrecciarono giustizialismo sommario e tumultuoso, parossismo nazionalista, rivalse sociali e un disegno di sradicamento della presenza italiana da quella che era, e cessò di essere, la Venezia Giulia. Vi fu dunque un moto di odio e di furia sanguinaria, e un disegno annessionistico slavo, che prevalse innanzitutto nel Trattato di pace del 1947, e che assunse i sinistri contorni di una "pulizia etnica". Quel che si può dire di certo è che si consumò - nel modo più evidente con la disumana ferocia delle foibe - una delle barbarie del secolo scorso.»'' from the official website of The Presidency of the Italian Republic, Giorgio Napolitano]
official speech for the celebration of "Giorno del Ricordo"
Quirinal, Rome, 10 February 2007. The estimated number of people killed in the foibe is disputed, varying from hundreds to thousands,
according to some sources 11,000
or 20,000.
The foibe massacres were followed by the Istrian–Dalmatian exodus.
The mass bombing of cities in Europe and Asia has often been called a war crime, although no Positive international law, positive or specific Customary international law, customary international humanitarian law with respect to aerial warfare existed before or during World War II. The USAAF Air raids on Japan, bombed a total of 67 Japanese cities, killing 393,000 civilians, including from the atomic bombings of Hiroshima and Nagasaki, and destroying 65% of built-up areas.
Genocide, concentration camps, and slave labour
Nazi Germany
Nazi Germany (lit. "National Socialist State"), ' (lit. "Nazi State") for short; also ' (lit. "National Socialist Germany") (officially known as the German Reich from 1933 until 1943, and the Greater German Reich from 1943 to 1945) was ...

the Holocaust
The Holocaust, also known as the Shoah, was the genocide of European Jews during World War II. Between 1941 and 1945, Nazi Germany and its collaborators systematically murdered some six million Jews across German-occupied Europe; a ...
(which killed approximately 6million Jews) as well as for Nazi crimes against the Polish nation, killing 2.7 million ethnic Poles and 4million others who were deemed "life unworthy of life, unworthy of life" (including the Disability, disabled and Mental disorder, mentally ill, German mistreatment of Soviet prisoners of war, Soviet prisoners of war, Romani people, Romani, homosexuals, Freemasons, and Jehovah's Witnesses) as part of a program of deliberate extermination, in effect becoming a "Genocide, genocidal state". German mistreatment of Soviet prisoners of war, Soviet POWs were kept in especially unbearable conditions, and 3.6 million Soviet POWs out of 5.7 million died in Nazi camps during the war.
[.] In addition to Nazi concentration camps, concentration camps, Extermination camp, death camps were created in Nazi Germany to exterminate people on an industrial scale. Nazi Germany extensively used Forced labour under German rule during World War II, forced labourers; about 12 million Ostarbeiter, Europeans from German-occupied countries were abducted and used as a slave work force in German industry, agriculture and war economy.
The Soviet Gulag became a ''de facto'' system of deadly camps during 1942–43, when wartime privation and hunger caused numerous deaths of inmates, including foreign citizens of Poland and Occupation of Baltic States, other countries occupied in 1939–40 by the Soviet Union, as well as Axis German prisoners of war in the Soviet Union, POWs. By the end of the war, most Soviet POWs liberated from Nazi camps and many repatriated civilians were detained in special filtration camps where they were subjected to NKVD evaluation, and 226,127 were sent to the Gulag as real or perceived Nazi collaborators.
![Czeslawa Kwoka - Brasse](https://upload.wikimedia.org/wikipedia/commons/2/26/Czeslawa_Kwoka_-_Brasse.jpg)
Japanese prisoner-of-war camps, many of which were used as labour camps, also had high death rates. The International Military Tribunal for the Far East found the death rate of Western prisoners was 27 per cent (for American POWs, 37 per cent), seven times that of POWs under the Germans and Italians. While 37,583 prisoners from the UK, 28,500 from the Netherlands, and 14,473 from the United States were released after the

, the number of Chinese released was only 56.
At least five million Chinese civilians from northern China and Manchukuo were enslaved between 1935 and 1941 by the East Asia Development Board, or ''Kōain'', for work in mines and war industries. After 1942, the number reached 10 million.
In Java, between 4and 10 million ''rōmusha'' (Japanese: "manual labourers"), were forced to work by the Japanese military. About 270,000 of these Javanese labourers were sent to other Japanese-held areas in Southeast Asia, and only 52,000 were repatriated to Java.
Occupation
![Palmiry before execution](https://upload.wikimedia.org/wikipedia/commons/8/89/Palmiry_before_execution.jpg)
In Europe, occupation came under two forms. In Western, Northern, and Central Europe (France, Norway, Denmark, the Low Countries, and the Protectorate of Bohemia and Moravia, annexed portions of Czechoslovakia) Germany established economic policies through which it collected roughly 69.5 billion reichsmarks (27.8 billion US dollars) by the end of the war; this figure does not include the Nazi plunder, sizeable plunder of industrial products, military equipment, raw materials and other goods. Thus, the income from occupied nations was over 40 percent of the income Germany collected from taxation, a figure which increased to nearly 40 percent of total German income as the war went on.

'' were never attained as fluctuating front-lines and Soviet scorched earth policies denied resources to the German invaders.
[.] Unlike in the West, the Racial policy of Nazi Germany, Nazi racial policy encouraged extreme brutality against what it considered to be the "Untermensch, inferior people" of Slavic descent; most German advances were thus followed by Generalplan Ost, mass executions. Although Resistance during World War II, resistance groups formed in most occupied territories, they did not significantly hamper German operations in either the East or the West until late 1943.
In Asia, Japan termed nations under its occupation as being part of the Greater East Asia Co-Prosperity Sphere, essentially a Japanese hegemony which it claimed was for purposes of liberating colonised peoples. Although Japanese forces were sometimes welcomed as liberators from European domination, Japanese war crimes frequently turned local public opinion against them.
[.] During Japan's initial conquest, it captured of oil (~550,000 tonnes) left behind by retreating Allied forces; and by 1943, was able to get production in the Dutch East Indies up to of oil (~6.8 million tonnes), 76 per cent of its 1940 output rate.
Home fronts and production
In Europe, before the outbreak of the war, the Allies had significant advantages in both population and economics. In 1938, the Western Allies (United Kingdom, France, Poland and the British Dominions) had a 30 percent larger population and a 30 percent higher gross domestic product than the European Axis powers (Germany and Italy); if colonies are included, the Allies had more than a 5:1 advantage in population and a nearly 2:1 advantage in GDP.
[.] In Asia at the same time, China had roughly six times the population of Japan but only an 89 percent higher GDP; this is reduced to three times the population and only a 38 percent higher GDP if Japanese colonies are included.
The United States produced about two-thirds of all the munitions used by the Allies in World War II, including warships, transports, warplanes, artillery, tanks, trucks, and ammunition.
Though the Allies' economic and population advantages were largely mitigated during the initial rapid blitzkrieg attacks of Germany and Japan, they became the decisive factor by 1942, after the United States and Soviet Union joined the Allies, as the war largely settled into one of Attrition warfare, attrition.
[.] While the Allies' ability to out-produce the Axis is often attributed to the Allies having more access to natural resources, other factors, such as Germany and Japan's reluctance to employ women in the Workforce, labour force, Allied Strategic bombing during World War II, strategic bombing, and Germany's late shift to a war economy contributed significantly. Additionally, neither Germany nor Japan planned to fight a protracted war, and had not equipped themselves to do so. To improve their production, Germany and Japan used millions of Slavery, slave labourers; Forced labour under German rule during World War II, Germany used about 12 million people, mostly from Eastern Europe,
while Slavery in Japan, Japan used more than 18 million people in Far East Asia.
Advances in technology and warfare
![Boeing-Whichata B-29 Assembly Line - 1944](https://upload.wikimedia.org/wikipedia/commons/9/91/Boeing-Whichata_B-29_Assembly_Line_-_1944.jpg)
Aircraft were used for Reconnaissance aircraft, reconnaissance, as fighter aircraft, fighters, bombers, and close air support, ground-support, and each role was advanced considerably. Innovation included airlift (the capability to quickly move limited high-priority supplies, equipment, and personnel);
[.] and of
strategic bombing
Strategic bombing is a military strategy used in total war with the goal of defeating the enemy by destroying its morale, its economic ability to produce and transport materiel to the theatres of military operations, or both. It is a systematica ...
(the bombing of enemy industrial and population centres to destroy the enemy's ability to wage war). Anti-aircraft warfare, Anti-aircraft weaponry also advanced, including defences such as radar and surface-to-air artillery. The use of the jet aircraft was pioneered and, though late introduction meant it had little impact, it led to jets becoming standard in air forces worldwide. Although Missile, guided missiles were being developed, they were not advanced enough to reliably Surface-to-air missile, target aircraft until some years after the war.
Advances were made in nearly every aspect of naval warfare, most notably with aircraft carriers and submarines. Although Aeronautics, aeronautical warfare had relatively little success at the start of the war, Battle of Taranto, actions at Taranto, Attack on Pearl Harbor, Pearl Harbor, and the Battle of the Coral Sea, Coral Sea established the carrier as the dominant capital ship in place of the battleship.
[.] In the Atlantic, escort carriers proved to be a vital part of Allied convoys, increasing the effective protection radius and helping to close the Mid-Atlantic gap. Carriers were also more economical than battleships because of the relatively low cost of aircraft and their not requiring to be as heavily armoured. Submarines, which had proved to be an effective weapon during the World War I, First World War,
[.] were anticipated by all sides to be important in the second. The British focused development on Anti-submarine warfare, anti-submarine anti-submarine weapon, weaponry and tactics, such as sonar and convoys, while Germany focused on improving its offensive capability, with designs such as the German Type VII submarine, Type VII submarine and Wolfpack (naval tactic), wolfpack tactics.
[.] Gradually, improving Allied technologies such as the Leigh light, Hedgehog (weapon), hedgehog, Squid (weapon), squid, and Mark 24 mine, homing torpedoes proved victorious over the German submarines.
![Bundesarchiv Bild 141-1880, Peenemünde, Start einer V2](https://upload.wikimedia.org/wikipedia/commons/3/3c/Bundesarchiv_Bild_141-1880%2C_Peenem%C3%BCnde%2C_Start_einer_V2.jpg)
Land warfare changed from the static front lines of trench warfare of World War I, which had relied on improved artillery that outmatched the speed of both infantry and cavalry, to increased mobility and combined arms. The tank, which had been used predominantly for infantry support in the First World War, had evolved into the primary weapon.
[.] In the late 1930s, tank design was considerably more advanced than it had been during World WarI, and Tanks in World War II, advances continued throughout the war with increases in speed, armour and firepower. At the start of the war, most commanders thought enemy tanks should be met by tanks with superior specifications.
[.] This idea was challenged by the poor performance of the relatively light early tank guns against armour, and German doctrine of avoiding tank-versus-tank combat. This, along with Germany's use of combined arms, were among the key elements of their highly successful blitzkrieg tactics across Poland and France.
Many means of Anti-tank warfare, destroying tanks, including Indirect fire, indirect artillery, anti-tank guns (both towed and Self-propelled gun, self-propelled), Anti-tank mine, mines, short-ranged infantry antitank weapons, and other tanks were used.
Even with large-scale mechanisation, infantry remained the backbone of all forces,
[.] and throughout the war, most infantry were equipped similarly to World War I.
[.] The portable machine gun spread, a notable example being the German MG 34, and various submachine guns which were suited to close combat in urban and jungle settings.
The assault rifle, a late war development incorporating many features of the rifle and submachine gun, became the standard post-war infantry weapon for most armed forces.
![Trinity device readied](https://upload.wikimedia.org/wikipedia/commons/8/88/Trinity_device_readied.jpg)
Most major belligerents attempted to solve the problems of complexity and security involved in using large codebooks for cryptography by designing ciphering machines, the most well known being the German Enigma machine. Development of SIGINT (''sig''nals ''int''elligence) and cryptanalysis enabled the countering process of decryption. Notable examples were the Allied decryption of
Japanese naval codes
The vulnerability of Japanese naval codes and ciphers was crucial to the conduct of World War II, and had an important influence on foreign relations between Japan and the west in the years leading up to the war as well. Every Japanese code was e ...
and British Ultra, a Bombe#The British Bombe, pioneering method for decoding Enigma benefiting from information given to the United Kingdom by the Polish Cipher Bureau#Gift to allies, Polish Cipher Bureau, which had been decoding early versions of Enigma before the war. Another aspect of military intelligence was the use of deception, which the Allies used to great effect, such as in operations Operation Mincemeat, Mincemeat and Operation Bodyguard, Bodyguard.
Other technological and engineering feats achieved during, or as a result of, the war include the world's first programmable computers (Z3 (computer), Z3, Colossus computer, Colossus, and ENIAC), V-1 flying bomb, guided missiles and V-2 rocket, modern rockets, the Manhattan Project's development of nuclear weapons, operations research and the development of Mulberry harbour, artificial harbours and Operation Pluto, oil pipelines under the English Channel. Penicillin was first mass-produced and used during the war (see History of penicillin#Stabilization and mass production, Stabilization and mass production of penicillin).
