We are in a nuclear era with a different mentality from over a half century ago. Today's threat is more from the escalating egos of national leaders, whereas in the 1950s the ultimate potential was demonstrated by war-ending events in Japan that brought fear to the masses. I believe society today acknowledges and accepts the destructive capabilities humanity now possesses and the uncertainty of our future lies more with our national leaders who are exhibiting increasing verbal attacks and silly claims of "my button is bigger than yours."
