As with WWI, World War II used total war tactics:
On the battlefront, blitzkrieg tactics were used, cities were firebombed, kamikaze attacks & atomic bombs were used
On the homefront, gov’ts used propaganda, conscription, rationing, & raised money to win the war

11. End of the War in Europe Yalta Conference (Feb 1945)
USA, England, Russia met twice before WWII ended to discuss the reconstruction of Europe after the war:
Yalta Conference (Feb 1945)
Potsdam Conference (July 1945)

13. Yalta Conference
In February 1945 (while the war was still being fought), the “Big Three” Churchill (England), Roosevelt (USA), Stalin (USSR) met in Yalta, USSR to discuss Europe after WWII
This is FDR’s last meeting (died in April 1945)

14. Yalta Conference At Yalta, the Allies discussed:
The Axis Powers must unconditionally surrender
The League of Nations should be replaced by a United Nations to keep the peace after the war
Germany would be divided into occupied zones to help rebuild
Eastern European nations have the right to choose to be democratic or communist
Self Determination

15. Potsdam Conference (Stalin, Truman, Churchill) US President FDR died in April & VP Harry Truman became the new President

16. Potsdam Conference
Stalin broke his promise at Yalta & began pressuring Eastern European countries to become Communist
After Germany surrendered, the USA, England, & USSR met at Potsdam, Germany to discuss the end of the war
Two important things happened

17. At Yalta, Stalin agreed to allow self-determination in Eastern Europe
Potsdam Conference
Potsdam ended any sense of friendship between the USA & USSR & began an era of bitterness & distrust called the Cold War
At Yalta, Stalin agreed to allow self-determination in Eastern Europe
Germany was divided into 4 occupied zones: 3 were democratic & 1 was communist
By Potsdam, Stalin had extended his control over Eastern Europe to create a buffer zone between the USSR & its future enemies
Potsdam presents a major Cold War theme: Because they could not agree on how do govern Europe, Truman & Stalin divided it

18. Potsdam Conference
President Truman was told that the atomic bomb was ready
Truman issued the “Potsdam Declaration” & told Japan to unconditionally surrender OR face "prompt & utter destruction"
