Berlin wall & Korea

As we look back to the Second World War, Germany, a fascist power initiated the war and targeted UK, France and the USSR. The end of the war saw the world split into two and the start of the Cold War between the USA and USSR. In the post-world war era, East and West Europe were ideologically divided, assisted by the USSR and the USA respectively.
As a result, Germany was also split into two by a wall erected on the 13th and 14th August 1961. After the collapse of Communism in 1989, the Wall also came down and the country was reunited..
From the above what I would like to say is that Korea was also divided with an invisible wall. North Korea still is being ruled by socialist ideology, while South Korea by capitalist policy. They do not have good relationship, not even a link or communication between the peoples of the two states although they are of the same origin. USA is playing a 'divide and rule' policy for its own interest. The outcome has not been positive because of the biased role of the United States.
