The "Peace Dam"

In response to a "water bomb" scare where North Korea would drown out Seoul with nuclear impact-like force with water, South Korea constructed the "Peace Dam"- a $429 million dollar project which now stands nearly 2000 ft. high. The Dam, today, holds no fuctionality, it simply protects them from North Korea. Silly.
