Quick answers
Are the scores a ranking of nations or armies?
No. Scores are browsing aids inside an era-bounded atlas — not live league tables of countries.
How many people died?
Scholarly ranges centre on about 70-85 million dead, including combatants and civilians. The Soviet Union (about 24-27 million) and China (about 15-20 million, wide range) are the largest national totals. Precise counts remain impossible.
What was the Holocaust in this war?
Nazi Germany and collaborators murdered about six million Jews, using ghettos, shooting pits and killing centres, alongside mass murder of Roma, disabled people, Soviet POWs and others. It is documented as genocide within the wider war, not a side-effect.
Why did the Allies win?
No single cause. Coalition resources, Soviet manpower and industrial relocation, US production and sea power, intelligence, and Axis strategic overreach all matter. Historians argue about weights; they do not treat victory as destiny.
What ended the war in the Pacific?
Japan announced surrender on 15 August 1945 after the Hiroshima and Nagasaki bombings and the Soviet invasion of Manchuria; the formal instrument was signed on 2 September 1945 aboard USS Missouri. Debate continues on the relative weight of those shocks.
How did the war change Korea?
Japanese colonial rule collapsed in August 1945. US and Soviet occupation zones met at the 38th parallel, creating two Korean states by 1948 and the setting for the 1950-53 Korean War.
About 70-85 million dead is the working scholarly band, not a precise census. Civilian shares were highest in China, the USSR, Poland and Yugoslavia.
Material cost included ruined cities (Warsaw, Stalingrad, Tokyo, Hamburg), lost shipping, and a leap in public debt that recast postwar welfare and tax states.
Bands
Civilian deaths
A majority of the 70-85 million band -- siege, massacre, famine, bombing and genocide.
Holocaust
About six million Jews murdered; other Nazi mass-murder programmes add millions more.
Displaced
Tens of millions of refugees and expellees in 1944-47, especially in Central Europe and East Asia.
Fiscal overhang
US, UK and dominion debt plus destroyed capital stock in Germany, Japan, the USSR and China.
Regions
Soviet Union
About 24-27 million dead, scholarly range; western oblasts destroyed; industry moved east.
China
About 15-20 million dead, wide scholarly range; Japanese occupation, famine and resumed civil war.
Central/Eastern Europe
Poland's Jewish community destroyed; Warsaw razed; borders shifted west in 1945.
Germany and Japan
Cities firebombed; occupation and demilitarisation; later economic recoveries under US protection.
British Empire/Commonwealth
Forces from India, Africa, Canada, Australia and New Zealand; home-front rationing and later decolonisation.
Korea
Liberated from Japan in 1945 into a split occupation that became two states and a 1950 war.

Makers
US war industry
Willow Run, shipyards and the Manhattan Project -- production as a strategic fact.
Soviet relocation
Plants moved beyond the Urals in 1941-42 kept the Red Army supplied.
British/Commonwealth yards
Escorts, bombers and radar as survival tools in 1940-43.
German armaments
Late rationalisation under Speer; still short of oil and transport.
Japanese industry
Unable to replace merchant ships or secure fuel after 1944.
Occupied labour
Forced labour from Europe and Asia was part of Axis production -- a crime, not a footnote.
Famine in Bengal (1943), Greece and Vietnam (1944-45) belongs in the cost ledger beside battle deaths.
Displaced persons and ethnic cleansing in 1945-47 -- Poles, Germans, Indians in Southeast Asia -- were part of the war's bill, not a separate peacetime story.
