What was an outcome of the Korean War

The Korean war had different and several outcomes depending on the country. First and most important for Korea:

"After the war, North Korea and South Korea remained divided. Families were broken up by the war and lived on opposite sides of the demilitarised zone, unable to visit or even communicate with each other.

The impact of the Korean War on the civilian population was especially dramatic. Korean civilian casualties - dead, wounded and missing - totalled between three and four million during the three years of war (1950-1953).

The war was disastrous for all of Korea, destroying most of its industry.

North Korea fell into poverty and could not keep up with South Korea's economic pace.

Even after fighting in Korea had stopped, US soldiers remained stationed in South Korea, which was an irritation for the Chinese government and put pressure on relations between the two countries."

For the USA, it had a sort of different internal and external outcomes:

"The USA managed to prevent South Korea falling into communist hands but the fear of the domino theory was to impact on US foreign policy decisions for the next 20 years.

The war led to massive American rearmament. Their defence budget shot up to $48 billion in 1951 and $60 billion by 1952.

The Korean War had a further legacy as well with 50,000 American soldiers killed. It was also the first war that the US entered and did not win outright."
