The Aftermath WWII left behind
World War II had two main theaters: the South Pacific and Europe. The latter was a result of the Holocaust and Hitler's rise to power in Nazi Germany, where he took over, named himself dictator, and went on to invade nearby countries and create his own powerful Third Reich to provide a means to his beliefs and goals as a leader. Although the Holocaust started out as simple discrimination, it ended up as a mass murder that took the lives of more than 11 million people for no other reason than the fact that they were not 'fit' to be a part of the Master Race.
Nazi ideals encouraged the eradication of anyone that did not meet the standards of this Master Race, but Adolf Hitler somehow decided that Jews needed to be especially singled out. This was likely a result of his own life experiences and the things he had learned about anti-Semitism during his time in Vienna. Although the war went on for many years, it didn't overtake Germany and its neighboring countries until 1945. The aftermath involved the devastation of the cities, the lives lost, and the millions of displaced persons who had nowhere to go.
People who survived the Holocaust and Hitler's reign were left to their own devices, for the most part. The Allied powers attempted to create prison camps for war criminals and their families after the war, as well as displaced persons camps for those who couldn’t return home or who had no home to return to. The problem was that cities were destroyed, countries were balking at the idea of helping survivors by allowing them to emigrate, and that politics and policy were getting in the way of basic human decency. This created a huge rift between the Holocaust survivors and the rest of the world.
Germany, Austria, Poland, and other nearby areas were totally or partially devastated by the war. The concentration camps were all but destroyed, with the exception of a remaining few that were salvaged for historical purposes. Thousands of Nazi war criminals were tried, sentenced, imprisoned, and executed for their involvement in this horrific tragedy that took place over 12 years in Germany. There were all kinds of problems left behind after the war ended, but some were worse than others. While destroyed cities and unstable politics were definitely issues at the time, one of the most important things after the war was the lives of survivors and how they were forever changed.
