Axis collapse, Allied victory (1944–45)On 16 December 1944, Germany made a last attempt on the Western Front by using most of its remaining reserves to launch a mive counter-offensive in the Ardennes to split the Western Allies, encircle large portions of Western Allied troops and capture their primary supply port at Antwerp to prompt a political settlement. By January, the offensive had been repulsed with no strategic objectives fulfilled. In Italy, the Western Allies remained stalemated at the German defensive line. In mid-January 1945, the Soviets and Poles attacked in Poland, pushing from the Vistula to the Oder river in Germany, and overran East Prussia. On 4 February, US, British, and Soviet leaders met for the Yalta Conference. They agreed on the occupation of post-war Germany, and on when the Soviet Union would join the war against Japan.

In February, the Soviets entered Silesia and Pomerania, while Western Allies entered western Germany and closed to the Rhine river. By March, the Western Allies crossed the Rhine north and south of the Ruhr, encircling the German Army Group B, while the Soviets advanced to Vienna. In early April, the Western Allies finally pushed forward in Italy and swept across western Germany, while Soviet and Polish forces stormed Berlin in late April. American and Soviet forces joined on Elbe river on 25 April. On 30 April 1945, the Reichstag was captured, signalling the military defeat of Nazi Germany.Several changes in leadership occurred during this period. On 12 April, President Roosevelt died and was succeeded by Harry Truman. Benito Mussolini was killed by Italian partisans on 28 April. Two days later, Hitler committed suicide, and was succeeded by Grand Admiral Karl Dönitz.^.. German forces surrendered in Italy on 29 April. Total and unconditional surrender was signed on 7 May, to be effective by the end of 8 May. German Army Group Centre resisted in Prague until 11 May.In the Pacific theatre, American forces accompanied by the forces of the Philippine Commonwealth advanced in the Philippines, clearing Leyte by the end of April 1945. They landed on Luzon in January 1945 and recaptured Manila in March following a battle which reduced the city to ruins. Fighting continued on Luzon, Mindanao, and other islands of the Philippines until the end of the war. On the night of 9–10 March, B-29 bombers of the US Army Air Forces struck Tokyo with incendiary bombs, which killed 100,000 people within a few hours. Over the next five months, American bombers firebombed 66 other Japanese cities, causing the destruction of untold numbers of buildings and the deaths of between 350,000–500,000 Japanese civilians.Japanese foreign affairs ministerMamoru Shigemitsu signs theJapanese Instrument of Surrender on board the USS Missouri, 2 September 1945In May 1945, Australian troops landed in Borneo, over-running the oilfields there. British, American, and Chinese forces defeated the Japanese in northern Burma in March, and the British pushed on to reach Rangoon by 3 May. Chinese forces started to counterattack in Battle of West Hunan that occurred between 6 April and 7 June 1945. American naval and amphibious forces also moved towards Japan, taking Iwo Jima by March, and Okinawa by the end of June.At the same time American bombers were destroying Japanese cities, American submarines cut off Japanese imports, drastically reducing Japan's ability to supply its overseas forces.












On 11 July, Allied leaders met in Potsdam, Germany. They confirmed earlier agreements about Germany, and reiterated the demand for unconditional surrender of all Japanese forces by Japan, specifically stating that "the alternative for Japan is prompt and utter destruction". During this conference, the United Kingdom held its general election, and Clement Attlee replaced Churchill as Prime Minister.The Allies called for unconditional Japanese surrender in the Potsdam declaration of 27 July, but the Japanese government was internally divided on whether to make peace and did not respond. In early August, the United States dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki. Like the Japanese cities previously bombed by American airmen, the US and its allies justified the atomic bombings as military necessity to avoid invading the Japanese home islands which would cost the lives of between 250,000–500,000 Allied troops and millions of Japanese troops and civilians. Between the two bombings, the Soviets, pursuant to the Yalta agreement, invaded Japanese-held Manchuria, and quickly defeated the Kwantung Army, which was the largest Japanese fighting force. The Red Army also captured Sakhalin Island and the Kuril Islands. On 15 August 1945, Japan surrendered, with thesurrender documents finally signed aboard the deck of the American battleship USS Missouri on 2 September 1945, ending the war.^.


Aftermath
The Allies established occupation administrations in Austria and Germany. The former became a neutral state, non-aligned with any political bloc. The latter was divided into western and eastern occupation zones controlled by the Western Allies and the USSR, accordingly. A denazification program in Germany led to the prosecution of Nazi war criminals and the removal of ex-Nazis from power, although this policy moved towards amnesty and re-integration of ex-Nazis into West German society.Germany lost a quarter of its pre-war (1937) territory. Among the eastern territories, Silesia, Neumark and most of Pomerania were taken over by Poland, East Prussia was divided between Poland and the USSR, followed by the expulsion of the 9 million Germans from these provinces, as well as the expulsion of 3 million Germans from the Sudetenland in Czechoslovakia to Germany. By the 1950s, every fifth West German was a refugee from the east. The Soviet Union also took over the Polish provinces east of the Curzon line, from which 2 million Poles were expelled; north-east Romania, parts of eastern Finland, and the three Baltic states were also incorporated into the USSR.In an effort to maintain peace, the Allies formed the United Nations, which officially came into existence on 24 October 1945, and adopted the Universal Declaration of Human Rights in 1948, as a common standard for all member nations. The great powers that were the victors of the war—the United States, Soviet Union, China, Britain, and France—formed the permanent members of the UN's Security Council. The five permanent members remain so to the present, although there have been two seat changes, between the Republic of Chinaand the People's Republic of China in 1971, and between the Soviet Union and its successor state, the Russian Federation, following thedissolution of the Soviet Union. The alliance between the Western Allies and the Soviet Union had begun to deteriorate even before the war was over.Germany had been de facto divided, and two independent states, the Federal Republic of Germany and the German Democratic Republicwere created within the borders of Allied and Soviet occupation zones, accordingly. The rest of Europe was also divided into Western and Sovietspheres of influence. Most eastern and central European countries fell into the Soviet sphere, which led to establishment of Communist-led regimes, with full or partial support of the Soviet occupation authorities. As a result, Poland, Hungary, East Germany, Czechoslovakia,Romania, and Albania became Soviet satellite states. Communist Yugoslavia conducted a fully independent policy, causing tension with the USSR.Post-war division of the world was formalised by two international military alliances, the United States-led NATO and the Soviet-led Warsaw Pact; the long period of political tensions and military competition between them, the Cold War, would be accompanied by an unprecedentedarms race and proxy wars.In Asia, the United States led the occupation of Japan and administrated Japan's former islands in the Western Pacific, while the Soviets annexed Sakhalin and the Kuril Islands. Korea, formerly under Japanese rule, was divided and occupied by the US in the South and the Soviet Union in the North between 1945 and 1948. Separate republics emerged on both sides of the 38th parallel in 1948, each claiming to be the legitimate government for all of Korea, which led ultimately to the Korean War.In China, nationalist and communist forces resumed 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 Israelmarked the escalation of the Arab-Israeli conflict. While European colonial 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 decolonisation.The global economy suffered heavily from the war, although participating nations were affected differently. The US emerged much richer than any other nation; it had a 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 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.Recovery began with the mid-1948 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 German economic miracle. Italy also experienced an economic boom and the French economy rebounded. By contrast, the United Kingdom was in a state of economic ruin, and although it received a quarter of the total Marshall Plan istance, more than any other European country, continued 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 experienced incredibly rapid economic growth, becoming one of the most powerful economies in the world by the 1980s. China returned to its pre-war industrial production by 1952. ruined warsaw

  
Impact
Casualties and war crimesEstimates for the total number of casualties in the war vary, because many deaths went unrecorded. Most suggest that some 75 million people died in the war, including about 20 million military personnel and 40 million civilians. Many of the civilians died because of deliberate genocide, macres, m-bombings, disease, and starvation.The Soviet Union lost around 27 million people during the war, including 8.7 million military and 19 million civilian deaths. The largest portion of military dead were 5.7 million ethnic Russians, followed by 1.3 million ethnic Ukrainians. A quarter of the 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.Of the total number of deaths in World War II, approximately 85 percent—mostly Soviet and Chinese—were on the Allied side and 15 percent were on the Axis side. Many of these deaths were caused by war crimes committed by German and Japanese forces in occupied territories. An estimated 11 to 17 million civilians died either as a direct or as an indirect result of Nazi ideological policies, including the systematic genocide of around 6 million Jews during the Holocaust, along with a further 5 to 6 million ethnic Poles and other Slavs (including Ukrainians and Belarusians)—Roma, homosexuals, and other ethnic and minority groups. Hundreds of thousands (varying estimates) of ethnic Serbs, along with gypsies and Jews, were murdered by the Axis-aligned Croatian Ustaše inYugoslavia, and retribution-related killings were committed just after the war ended.
 world war II Death


In Asia and the Pacific, between 3 million and more than 10 million civilians, mostly Chinese (estimated at 7.5 million), were killed by the Japanese occupation forces. The best-known Japanese atrocity was the Nanking Macre, in which fifty to three hundred thousand Chinese civilians were raped and murdered. Mitsuyoshi Himeta reported that 2.7 million casualties occurred during theSankō Sakusen. General Yasuji Okamura implemented the policy in Heipei and Shantung.Axis forces employed biological and chemical weapons. The Imperial Japanese Army used a variety of such weapons during its invasion and occupation of China (see Unit 731) and in early conflicts against the Soviets. Both the Germans and Japanese tested such weapons against civilians and, sometimes on prisoners of war.The Soviet Union was responsible for the Katyn macre of 22,000 Polish officers, and the imprisonment or execution of thousands of political prisoners by the NKVD, in the Baltic states, and eastern Poland annexed by the Red Army.The m-bombing of civilian areas, notably the cities of Warsaw, Rotterdam and London; including the aerial targeting of hospitals and fleeing refugees by the German Luftwaffe, along with the bombing of Tokyo, and German cities of Dresden, Hamburg and Cologne by the Western Allies may be considered as war crimes. The latter resulted in the destruction of more than 160 cities and the death of more than 600,000 German civilians. However, no positive or specific customary international humanitarian law with respect to aerial warfare existed before or during World War II.  Chinese civilians being buried alive by soldiers of the Imperial Japanese Army, during the Nanking Macre, December 1937
