The U.S.s stepped up efforts to prevent the expansion of
communism in the world. Apart from that
they continue to maintain bases in South Korea in case the North would once
again launch an attack. The Korean war
also saw the integration of African Americans into the army, meaning there were
no segregated troops during this war.
If the change in values of one set doesn't affect the values of the other, then the variables are said to have "no correlation" or "zero correlation." A causal relation between two events exists if the occurrence of the first causes the other.
The Missouri Compromise was the laws that enacted in 1820 to maintain the balance of power between slave and free states. Henry Clay wanted Missouri (state) to be a free or a slave state but the Southerns claimed that the Constitution did not give the Congress the power to ban slavery. THey would worry that if free states formed a majority in Congress, they would ban slavery altogether. Meanwhile, Maine wanted to be part of the statehood, so Henry Clay suggested that Missouri could be a slave state and Maine as a free state but the Congress passes the Missouri Compromise so Maine became a free state and Missouri as a slave state (I think?). Among these tensions, the Mason Dixon line formed the Maryland and PA border. The line came to be used for the division between the slave states and free states, as well as the division between the north and south.(I hoped I answered your question!!)
Well for one, there was the idea that Communism was a direct threat to Democracy itself. That the rise of Communism would be the downfall of Democracy. As well, there was the fear that Communist countries would align with each other, the threat of nuclear war was already a huge scare and as such an alliance would have been seen as a threat to the US.
