2017 Nobel Peace Prize winner ICAN is calling for 'a different kind of debate around nuclear disarmament'.

The Pope is praying for a world without nuclear arms. Pope Francis on Sunday offered a prayer for world leaders to collaborate on nuclear disarmament, calling it an essential step for expanding human rights. His comments come after President Donald Trump and North Korean leader Kim Jong Un have spent much of the year threatening each other with hints of a nuclear conflict.

For centuries, following bloody conflicts, military leaders acknowledged that some weapons were simply too awful to be used, but those same militaries generally continued to use them.
