How did World War II affect the United States?
World War II impacted the United States in several ways. Once the Japanese attacked us at Pearl Harbor, the United States joined the war. This required a full commitment on the part of the American people. The attack on Pearl Harbor woke up many Americans who were skeptical about the United States being actively involved in world affairs.
After we were attacked, we needed to convert our industries to wartime production. The Reconstruction Finance Corporation gave loans to businesses and helped to cover the costs of switching from peacetime production to wartime production. With cost-plus contracts, businesses were guaranteed to make a profit producing war materials. Our businesses and the workers in those businesses worked very hard to provide the needed supplies and the needed weapons for our military. World War II brought us out of the Great Depression.
Soldiers were drafted and trained as early as September 1940. The soldiers were deployed all over the world during World War II. Americans who didn’t fight made sacrifices at home. Food and other supplies were rationed. People were encouraged to buy Victory Bonds. They also were cautioned to be careful about what they said regarding the war and to whom they spoke to about the war.
After World War II ended, the United States was the leader of the free world. We stood up to the Soviet Union and their attempts to spread communism around the world. The United States was considered a superpower after World War II ended.

What were the effects of WWII on the United States?
There were several effects of WWII on the United States, and I will summarize them below in terms of social and economic changes.
Economic Changes
The biggest impact of WWII on the United States was economic stimulation. In order to prepare for war, industry experienced a boom and continued to grow after the war ended.
Social Changes
After the war ended, there was a shift from urban, city life back to rural life—this time, however, in the form of suburbs. Families, supported by a strong and growing economy, were able to start purchasing homes outside the city and rely on either public transportation or cars to commute to jobs. Women were also working more, a result of their efforts to work to help support American troops during wartime. With a transition to suburban life came the growth of mass consumerism, as a better economy and growth in technology and industry led to a desire for new goods. This was also the period where the "baby boomer" generation was born; in a stable, post-war United States, populations exploded.
It should be noted, however, that African Americans did not enjoy the same prosperity. Racial tensions and divides, segregation, and Jim Crow laws in the South among other things encouraged the Civil Rights Movement.
What were the effects of WWII on the United States?
To expand on teachersage's answer, I would like to focus on the impact World War II had on the role of women in the economy. As teachersage noted, with most men away at war, it became the role of women to take up jobs in factories. There is no doubt that women on the home front contributed greatly to making sure that American factories pumped out the materials necessary for the men overseas to win the war. Out of necessity, this marked a departure from the traditional roles of women in society.
Before World War II, women were expected to stay home and take care of the household, or, if they did choose to work, to work in jobs that were traditionally done by women. Before World War II, women were also expected to stop working after marriage, or at least after having children. Upon marriage it became the duty of women to maintain the household and look after the children while the men worked.
Following World War II, many women hoped to remain in the workforce. They had experienced the benefits of earning their own money, and had proven that they could be successful participants in the American workforce. There was a drop in the number of women in the workforce in the years immediately after World War II due to the return of military men from overseas, but women would quickly rejoin the workforce in the decades that would follow. The experience of women in the workforce during World War II led to the eventual understanding that women could not only participate in the workforce, but could do so even after marriage and having children. The economic participation of women during World War II led to revolutionary changes to the role of women in the American economy and in American society in general.
What were the effects of WWII on the United States?
Though World War II was terrible and tragic because of lost lives, destroyed cities, and the Holocaust, it was good for the American economy. Providing materials for the war propelled the United States out of the Great Depression. Starting in 1939, the year the war began in Europe, jobs in the US abounded and the once high unemployment levels dropped virtually overnight. Suddenly, everyone could find a job.
Once the United States got into the war in late 1941, the economic situation only got better. It has been said that supply lines win wars, and the US was a huge supply line, putting its industrial might into churning out a seemingly endless number of planes, tanks, jeeps, uniforms, guns, grenades, and uniforms. With most of the men away at war, women worked around the clock in factories. Because of rationing, there was not much to buy, so people saved their money.
After the war, people quickly converted their savings into material goods, buying cars, clothes, houses, washing machines, and other consumer items in a frenzy of pent-up demand that fueled economic growth. Further, with most of Europe in shambles, the world depended on US factories to supply the goods and materials needed for rebuilding. After the war, the US took its place as the world's economic powerhouse.
What were the long-term effects of World War II?
World War II had many long-term effects. The United States and the Soviet Union became the two superpowers in the world; this would be one of the causes of the Cold War. The United States led the way in forming the United Nations in order to provide an outlet for the world to discuss its problems before another massive war took place. The most famous war crimes trial took place at Nuremberg where several Nazis were hung or imprisoned for crimes against humanity. This set the stage for later war crimes trials of other notorious leaders throughout the twentieth century. The nation of Israel was created as a Jewish homeland due to the horrific nature of the Holocaust. Israel has been influential both in Middle Eastern politics and world diplomacy ever since. The United States gave money to Western Europe through the Marshall Plan after World War II in order to combat Communism and support the economies of valuable trading partners. Most importantly, World War II saw the only use of an atomic weapon in wartime; ever since, world leaders have strenuously tried not to use this weapon.
In the United States, the return of the World War II veterans back to their homes led to the Baby Boom. This generation is still one of the most affluent and politically active generations in American history. The G.I. Bill, established in 1944, remains a valuable way to reward US veterans for their service and to assist with their transitions back to civilian life.
What were the most important effects of World War II on American domestic life?
World War II (1939–1945) was the largest conflict in human history, so it is not surprising that it had numerous effects on the American home front. These included economic, political, and social changes.
The large-scale conversion of the economy to meet the needs of the war ended the Great Depression. The Great Depression, which had begun in 1929, had had a severe and long-lasting impact on the American people. Unemployment and poverty reached record levels. Although the New Deal achieved some real success, the economy remained sluggish throughout most of the 1930s. Amazingly, 75,000 tanks and 275,000 planes were manufactured in preparation for the war. Automobile production virtually ended as consumer goods became unimportant. The government controlled all economic activity, and union activities were not tolerated. Howard Zinn, a renowned historian, believed wartime workers were often on strike because the profits were not shared in an equitable manner.
Women played an important role during the war. Although they did not see combat, thousands served in the military. As many as six million entered the labor force. They were needed because so many men had left to fight.
Minorities who had been enslaved or discriminated against were also patriotic. Some black people became famous for their excellent performance as Tuskegee airmen. Indians served honorably, and the Navajo language was used to mask America's military messages.
The most unfortunate and shameful episode on the home front was the incarceration of Japanese-Americans. They lost their businesses and their homes. German-Americans and Italian-Americans were not treated in a similar, shameful manner.
When the war ended in 1945, America was a transformed nation. It emerged much more powerful and more confident than it had ever been before. Its people were, overall, proud of their nation's role in the war.
What were the debilitating effects of World War II?
WWII was a great loss to the world. Trillions of dollars were lost in creating the weapons of war—these dollars could have gone towards rebuilding the consumer economies of Europe after WWI. All of the major combatants lost significant numbers of both soldiers and civilians, and it is impossible to predict what these people would have done with their lives in the future. The practice of carpet bombing led to the leveling of many major historic cities. The war led to the expansion of the Holocaust as Hitler found more Jews and Slavs in Eastern Europe to exterminate. The atomic bomb took one of the greatest sources of energy ever discovered, the atom, and turned it into a weapon of war that would shape the postwar relationship between the United States and the Soviet Union. The Soviet Union felt threatened enough to maintain a buffer system of Eastern European satellites while the United States continued its military spending for the next forty years and fought many proxy wars with the Soviet Union in Vietnam and Afghanistan.
