Those comments were directed mostly toward Korea and Iran, they may be fanatics but their not crazy.
First, I disagree with Nitro. I think there are some that crazy. Especially Korea (because they do not care about their people as has been demonstrated) and Iran (because they have developed a cult like status where all reason is thrown out for the good of the cult).
Ah, yes, the great irony of Nagasaki and Hiroshima. The atom is our savior.
In 1945, all we knew about Atomics was they were BIG bombs. The quest for big bombs did not stop with 1945 either (MOAB, bunker busters). It is easy to look back with the knowledge of the 21st century and see the genie we have unleashed, but at the time, all we knew was that it was a big mo-humper of a bomb. There was never any evil intention with it (outside of the fact that we were at war and millions had already died in it), and to assign 21st century knowledge to those of 1945 is both stupid and shallow.
And in another way, 1945 was inevitable. regardless of who invented it, and who had it, someone at someplace in sometime had to use it so that we could understand the terrible nature of the weapon. if it had never been used, it would be used today. At some point, a threat has to be used to be credible. We can take some solace in the fact that the time these were used, it literally saved millions of lives (Overlord).
