Only last night, talked about this with my brother. He was in the US Air Force stationed in Korea in 1962. He had visited [link|http://www.gluckman.com/NKBorder.html|"peace village"] at Panmunjom, North Korea three times. His fellow airmen were surprised to learn from him that there had been a war there less than 10 years prior. It's not just "how soon they forget", it's "they never had a fricken idea".
The 50th anniversary of the armistice has just been celebrated.
