The Holocaust was Hitler's idea of purifying German's blood and culture. Hitler and the Nazi's exterminated everyone who wasn't German, such as Jews and colored people. They had concentration camps where they tortured, raped, starved, and killed the non-Germans. If you refused any of Hitler's teachings or the Nazi's commands, you were killed on the spot. Didn't matter how old you were, there was no sympathy to anyone. This was hell on earth.
Operation Sea Lion
September 1, 1939 German forces invaded Poland. Hitler used his new military technology. It was blitzkrieg, and other people called it the lighting war. The invasion was filled with bombs, tanks, and a strong air force. Nazis attacked from the west and Stalin attacked from the East. After Poland was invaded, Germany used it as a "living space" for Germans.
Dunkirk was surrounded by three powerful European nations, and the battle fields of many bloody battles. This battle was called a "phony war." The blitzkrieg had all nations not surprised. Germany cut off all communication and transportation between north and south branches of the Allies. General John Gort had started to evacuate his troops from sea before the Nazi's got to them.
Defeat of Japan
Hitler planned Operation Sea Lion, which was to invade Britain. Him and the Nazi's launched air missiles to the nation. Everyday, Germany would bomb England's coast. But then they started bomb London and other surrounding cities. They attacked because they were afraid of the United Kingdom military's future plans against the Axis Powers.
The United States and Japan had always had a strong growing tension because of numerous reasons. Japan finally took action and bombed one of the U.S's fleet dock ships in Hawaii. The United States saw this coming, but didn't take any warning seriously. The day after this tragedy, President Roosevelt officially started the war between the U.S and Japan.
On August 15, 1945 Japan surrendered in World War II because of the atomic bombings in Hiroshima and Nagasaki. The United States had bombed the two cities because of the attack on Pearl Harbor. But then right after the bombings, The United States had helped rebuild and restore Japan.
