One of the crucial details that travel in individual’s understanding when the term “war” appears is viewed as the death of a few faultless citizens among other fearless patriots. War in this regard is associated as an act of invasion in another’s land through the use of an armed militia and other proponents of combat. World War II was a worldwide conflict that lasted nearly six years and resulted in heavy casualties of human lives and property in several parts of the world. It began on September 1, 1939 and ended on September 2, 1945. The war took the lives of about 17 million soldiers and an even greater number of civilians, who died as a result of bombings, starvation, and deliberate campaigns of mass murder. The war also ushered in the atomic age and was quickly followed by the collapse of the wartime alliance between the United States and the Soviet Union and the beginning of the Cold War. It has gone down in history as being one of the most gruesome wars ever fought. Most known facts about the war are the Tuskegee Airmen, Navajo Code Talkers, the Japanese-Americans from Hawaii, Japanese Internment Camps, and Women’s role in war. These people had a significant impact on the development of the United States and resulted from many sociopolitical doctrines, policies, and principles of international relations. During World War II, US military was segregated. The Tuskegee Airmen were a group of African-American men who flew for the United States. They trained at Tuskegee Army Airfield in Alabama. They flew many missions for the military and they were very successful in accomplishing their goals. The men were fighting discrimination and racism on two fronts. They were fighting to combat racism abroad and to prove that they should be treated equally within the United States. The Tuskegee Airmen flew in more than 700 bomber escort missions. During these bomber escort missions, they protected the bombers from enemy fighters. The Tuskegee Airmen was the only fighter group to have a perfect record protecting the bombers. The Tuskegee Airmen showed that they deserved every right to be treated as true American citizens. They waged the “Double V Campaign” against Germany abroad and against discrimination at home. Another important role that impacted World War II is The Navajo Code Talkers. They are people in the 20th century who used obscure languages as a means of secret communication during wartime. There have been more than 400 American Indian Navajo Code Talkers that time. But there are less than 30 non-Navajo persons who could understand such unwritten language. The Code Talkers’ role in war required intelligence and bravery. They developed and memorized a special code. They endured some of the most dangerous battles and remained calm under fire. They served proudly, with honor and distinction. Their actions proved critical in several important campaigns, and they are credited with saving thousands of American and allies’ lives. The Navajo Code Talkers had a big impact on the United States, which includes the war against the Japanese in the Pacific theater. They used their language as an unbreakable code that the Japanese could not decipher. The code was such a success and resulted in saving many lives in the war with Japan. In battle, they had to transmit their messages with the utmost care and accuracy under difficult circumstances. Their work saved lives and helped the United States achieve victories. The Navajo Code Talkers developed their own code dictionary. This dictionary was kept secret for many years and was only made public in 1968. Japanese Americans are Americans who are fully or partially of Japanese descent, especially those who identify with that ancestry, along with their cultural characteristics. Despite the lack of any concrete evidence, Japanese Americans were suspected of remaining loyal to their ancestral land.In the event of a Japanese invasion of the American mainland, Japanese Americans were feared as a security risk. The internment of Japanese Americans in the United States during World War II was the forced relocation and incarceration in camps in the western interior of the country between 110,000 and 120,000 people of Japanese ancestry, most of whom lived on the Pacific coast. The relocation of Japanese-Americans into internment camps during World War II was one of the most flagrant violations of civil liberties in American history. The Supreme Court upheld the legality of the relocation order in Hirabayashi v. United States and Korematsu v. United States. World War II provided unprecedented opportunities for American women to enter into jobs that had never before been open to women, particularly in the defense industry. Numbers of women working outside the home rose exponentially and they thought they were there to stay. During WWII women worked in factories producing munitions, building ships, aeroplanes, in the auxiliary services as air-raid wardens, fire officers and evacuation officers, as drivers of fire engines, trains and trams, as conductors and as nurses. The overall theme that was created by women in the workforce and the military was an increase in equality between the sexes and a huge change in gender roles. No longer were women looked down upon as they were before they aided in this huge public effort to promote the freedom and well being of the great Allied countries.
