Throughout its history, America has experienced myriad tragedies and victories, each of which has left a mark on its identity. But like all things, it didn't evolve into what it is overnight. Politics is the brain of the country, but people are the heartbeat. The direction of the former depends on the status of the latter and some events affect the citizens of a country irreparably. War shakes a nation to its core, transforming every aspect of society. Sometimes it's better that way, but not always. Over the last century the United States has had the misfortune of going through three wars, each very different. The turn of the century began with World War I, which brought economic and social changes to the nation, from the rise of Progressivism to the beginning of the journey for women's equality that would shape the political world of the 21st century. As for the subsequent world war, which broke out too soon, it gave America the long-admired patriotism and unity of thought on a national issue. Once again, women at war transformed their roles in society, but this time in an even greater way. However the economy did not fare so well and suffered even more due to Roosevelt's policies and massive fiscal measures that affected future deficit and budget decisions. To top it off, Vietnam was an even bigger disappointment for our nation. The riots and movements of the time regarding communism being the enemy, and the open hatred towards soldiers by the media severely damaged the war and the nation's view of it. Not to mention Nixon fueled the welfare beast and the EPA. All in all, despite every other event in American history, very few have had as much of a political impact on the nation as World War I, World War II... middle of the paper... completely, which would truly change the nation both politically and socially. Finally, the Vietnam War was quite disappointing. By embarrassing the government, giving no support to the troops, and transforming our nation's education, he left a bad mark that would never be completely erased. In conclusion, wars are perhaps the most influential factor in shaping a nation, and World War I, World War II, and Vietnam all played their part in making America what it is today. Works Cited1.
