"...the US is always going on about which countries can't be trusted with nuclear weapons when we were the only ones to ever use them."

Not a good example, Mary. Remember..WE were the ones attacked, and many thousands had died, and all we really knew was this thing made a BIG boom, and might stop the Japanese when nothing else had.

Everyone knows now what the details of using that bomb are, and what the different motives of some of those who have it are. Harry Truman had seen ONE big boom, and had only weeks to decide what to do. There was no time to debate guys like the one who spit at him.
