Wars have occurred in the past many times because of different things, such as fighting for land, reforms, or simply hatred towards each other. After wars, a treaty is signed or agreements are made; for example, the Treaty of Versailles was signed after the First World War. Different events and battles also happen during wars in order to win the war or gain control over it. During the American Revolutionary War, battles between the Americans and the British took place primarily in the 13 colonies controlled by the British, and the Americans fought for their independence. The Americans eventually won their independence from the British. This is an example of cause and effect of war. The causes of World War II were multiple, including Hitler's desire to conquer all of Europe and make it his own, as well as Germany, Italy, and Japan conquering their neighbors (Ellis and Esler, 925-929). After World War II, Germany, Japan, and the Allies learned to get along after the multiple events of World War II and it still affects the world today. The Germany of World War II was completely different from the Germany of today. At that time, Hitler was the official dictator hungry for power and land. He wrote the book Mein Kampf, which describes racism and hatred towards Jews, known as anti-Semitism, and which is currently banned in Germany. His book contained a lot of anti-Semitic propaganda and explained how he plans to take over the world and make "Germania" the capital. Because he despised Jews so much, he ordered Nazi soldiers to kidnap and send Jews to concentration camps to kill them, which is considered genocide against the Jews. In the camps, Jews worked, starved, and were sent to gas chambers for... middle of paper ...... ongoing Arab-Israeli conflict. In Japan and Germany, everything was ruined and dilapidated due to bombings and invasions. Germany was still divided between freedom in the west and communism in the east (Ellis and Esler 955). Communism spread to different countries, this is called the domino theory, which led to the Cold War (Ellis and Esler 993). The Cold War, a period marked by tensions between the Allies and the Soviet Union; it was essentially a fight against communism as it spread (Ellis and Esler 954). After the Cold War, Berlin was demolished and communism was wiped out in Germany, while some countries retained it as their standard mode of government (Ellis and Esler 1004-1006). Today, only five communist countries remain and most countries have adopted democracy. After World War II, things were definitely not the same.
