this day in history, 1945.

Any idea what happened in 1945 on this date? Is it me or do we not as Americans hear much about this? I can think of a lot of movies on World War II, but I cannot really think any that deal with the nuclear bombs the US dropped on Japan. As I type I am watching the HBO documentary: White Light, Black Rain which is very well done (at least what I have seen so far). If you get HBO, I would recommend watching.
