Czechoslovakia was a nation for 74 years. From 1918–1992.
Answer:
The United States needed a close enough military base, to plan and execute a full invasion of the Japanese mainland.
Explanation:
Okinawa stood in a strategic position in the Pacific Ocean. Its proximity to Japan provided a good spot of the United States and the Allies to set up a military base to plan a full out invasion of Japan.
From Okinawa, the U.S had a close enough range to deploy their warplanes and also transport their full artillery and since Okinawa was not landlocked, the United States could easily bring in supplies and reinforcements through the Pacific for the battle against Japan.
The election of Andrew Jackson dramatically changed the US for several different reasons including:
1) He was an advocate for the "average citizen"- Andrew Jackson was dubbed the "Champion of the Common Man." He received this title because he was not an inherently wealthy man nor was he part of a family that was consistently in politics. Rather, he came from humble beginnings. This story inspired many American citizens.
2) His policies resulted in increased democracy in the US- Jackson helped to get rid of property qualifications and other restrictions to ensure that white farmers had the right to vote, regardless of how much property they owned.
