It was great to see the unified Korean team come into the Olympic stadium for the opening ceremony. One could argue that Korea is the only divided country that remains in the world. For example, there was North and South Vietnam (united in 1975), East and West Germany (united in 1990), and South North and South Yemen (also united in 1990). And yes, the Soviet Union collapsed in 1991, but one cannot see it become one country again.
I read that support for Korean unification is fading, though. Some 50% of young South Koreans regard North Korea as an outright enemy, that they want nothing to do with. The harsh reality is that there is a yawning chasm between the economies of the countries. The per capita income difference between the South and North is 20 to 1. For West Germany and East Germany it was 3 to 1.
