Deutschland wurde im Jahr 1945 in der Bundesrepublik Deutschland und Ost-Deutschland geteilt. Dann ist die DDR baute eine Mauer um Westen Berlin, aber die Mauer wurde im Jahr 1990 abgerissen, und das wiedervereinigte Deutschland wurde.
Germans, regardless of their regional background, got screwed by the Allies and Soviet Union. Currently, both East and West Germans are suffering. West Germans' tax being spent more toward East Germany, and East Germans are still doing poor relative to the West Germans. This suffering can be attributed to the division between the East and West Germany which was caused by the selfish interest of the USA and USSR. Both countries, in order to protect their political interest and their country from foreign influences, they divided the Germany as a buffer zone. Division of the country for 45 years and reunification caused so much disparity in the culture, politics, and economy. Even after reunification of 12 years, they still consider themselves different.
This happened the same to the Korean peninsula. They were divided into North and South due to the political interest from the USSR and USA. Currently, the peninsula is still divided, and it has been 67 years. As it still is for Germany, the disparity in culture, politics, and economy is very big in Korea. Most South Koreans actually don't want reunification; they saw the what Germany had to go through, and the South Koreans who are doing much better than North Koreans, don't want to suffer. It is quite interesting how the reunification of the Korean peninsula will go, if it's every going to happen.
