"The camera spots a smiling North Korean girl. She is enjoying an intimate moment with her boyfriend in a Pyongyang park. It is quiet and peaceful here, just like it is in the rest of the country nowadays. But it hasn't always been this way. 
The Korean War in the 1950s left the country in ruins, especially in the north, where many historic sites were devastated by bombs. Pyongyang also suffered greatly. The United States dropped 428,000 bombs on its 400,000 population."
