In fact , USA is the only retarded country that used a nuclear weapon before .
The Americans killed half a million Japanese with the nuclear attack in 1945, as Japan was preparing to surrender. For me, the US is a greater threat to the world peace than Iran. After the WW2 was over, most of the Nazi and Japanese generals, who had committed crimes against humanity were brought to trial, and most of them were sentenced to death. But what about the Americans who had committed crimes against humanity during the WW2?
