3. Hitler and the Nazis hated Communism (Fascism hated communism) ***Yet Hitler didn’t want the Soviets fighting in 1939 ***Stalin wasn’t ready for entering war either ***Signed a Non-Aggression Pact (neither side would attack each other)

4. Allied leaders, Churchill, Roosevelt, Stalin and DeGaulle met throughout the war to plan strategy and make post-war plans

6. Major Points of the War ***Hitler attacked the Soviet Union in June of 1941. (violated Non-Aggression Pact) Stalin wanted the United States and the allies to go into France to open a second front. However, Churchill and Roosevelt did not feel their armies were ready for an invasion of France. Instead they attacked the Germans in North Africa because Axis control of the area prevented the Allies from using the Suez Canal. The Allies successfully launched ***Operation Torch in November of 1942. (Military operation to defeat Axis Powers in North Africa)

They were on the offensive from this point onward.

42. Winning the War in the Pacific Okinawa was at the southern end of the Japanese homelands. The next step would be to invade Japan itself. The battles of the island hopping campaign demonstrated the tenacity of the Japanese soldier. It was estimated that 1,000,000 U.S. causalities would be sustained. There was another option opened up by the ***Manhattan Project that developed and tested this first Atomic Bomb in New Mexico ***The new President Harry Truman ordered the two bombs be dropped and on August 6 th, 1945 Hiroshima was bombed. On August 9 th Nagasaki was bombed. ***Japan surrendered on August 14 th, 1945 (V-J Day) and World War II was over.
