My dear Kacvey,
40 years ago, Cambodia fell into the hands of the KRs. You already know the rest that you live with until the present day.
Let read, in silence, the page of history on that day as re-memorized by Denis Gray of the Associated Press and published by the Stars and Stripes Newspaper.
May those who died find Peace. May those who survive find courage to prowl and work for Peace.
