I was just lurking around GD when I came across this thread. The OP mentions that today is the 58th anniversary of the dropping of the bomb on Hiroshima.
I misread the OP and his link to mean that a new bomb yesterday.
I immediately checked snopes to see if it really happened. They said nothing. I then looked at the headlines of different news sites to see what they had on this bombing. I was amazed that this none of them thought that this was headline news.
Anyway, I looked more closely at the OP’s link and looked right at the top of the page, where it said On This Day. Oh well.
