The U.S.A, or the United States of America, is a federal republic composed of 50 states and is one of the world's leading superpowers. Emerging from World War II with a strong economy and military, the U.S.A played a pivotal role in shaping global politics, economics, and culture in the second half of the 20th century. Its influence, marked by a commitment to democracy and capitalism, established it as a counterweight to the Soviet Union during the Cold War.
