I just watched the movie. Wow. A great story told powerfully.
There was so much I did not know about the Manhattan Project and the politics behind it.
We are faced with moral choices every day, but I can't imagine the incongruity of building a weapon like this. You need the weapon to stop evil, before that evil makes that awful weapon itself.
And when the evil is waning, soon to collapse, should you use that weapon? Should you use it a second time?
The world has never been the same since that first explosion in Los Alamos.
We do well consider the evil and destruction of violence, even as a means of stopping violence.
