The topic of D-Day is an interesting one; it tells so much about the history of the world and how society has evolved. On D-Day, the United States used several new tactics that the world had never seen, but those same tactics are seen throughout the military today. Paratrooping is a good example of a new tactic. Paratrooping dropped troops right in the middle of the battle, behind enemy lines, which allowed them to attack from within. Military officials also learned a great deal from D-Day, from the drowning of their men to the necessity of air support. D-Day formed a basic plan that armies could use in later battles. The idea of using air support to disable communications and transportation might have been the only thing that kept them from dying immediately. If the United States had not weakened the German defenses prior to the assault more soldiers would have died on the beach. The military also learned about the importance of cover, when the men ran to the beach there was no cover, just open land that made them easy targets. Not only did the United States learn new military tactics, they learned about the importance of allies. The United States has been allies with other countries before World War II, but the alliance during World War II was much more substantial and important to the future of the war. Allies such as Canada and Great Britain aided the United States during the battle at Normandy. Without allies the United States would not have been able to push through the enemy's front lines. Allies in Europe could send more troops in battle because they were geographically closer to the fighting than the United States. An example would be Russia, because if they had not attacked Germany from the East the Nazi's would have been much more powerful and harder to defeat. The Nazi’s could have gained control over all of Europe if Russia had not stepped in. D-Day was the most influential day of World War II that led to the victory of the Allies and the defeat of the Nazi regime and if it did not occur the Allies may have lost the war. If the Allies had not won the war in 1945 the Holocaust may have continued as well, and millions of people would have been killed. It is the responsibility of the current generation to ensure that a tragedy like this does not happen again. Winston Churchill, the British Prime Minister during World War II, once said, “Those that fail to learn from history are doomed to repeat it.” If younger generations do not learn about history it is bound to happen again and in larger scale as technology advances. Personally, this project has greatly increased the relevancy of D-Day and the Holocaust in everyday life.
