Yes world leaders learns something on this,they learn that atomic bomb was not powerful enough to destroy Hiroshima and Nagasaki,still there were so many survivors that when they see up to today,it bleeds their hearts.Thats why they create more powerful nuclear bombs that can melt entire nation and turn all things to dust further reducing more sufferings with an instant death,for those survivors still they die due to nuclear fall outs.So for today those big nations takes the monopoly to acquire and built more nuclear bombs so that they will be called super powers and play little gods. UN is powerless just educating smaller nation to sign non nuclear P-treaty so as not be a part in chaos.
