“With deep conviction I wish once more to declare that the use of atomic energy for purposes of war is today, more than ever, a crime not only against the dignity of human beings but against any possible future for our common home. The use of atomic energy for purposes of war is immoral, just as the possessing of nuclear weapons is immoral, as I already said two years ago. We will be judged on this. Future generations will rise to condemn our failure if we spoke of peace but did not act to bring it about among the peoples of the earth.  How can we speak of peace even as we build terrifying new weapons of war?”

Pope Francis calls for a world free of nuclear weapons

Visiting Japan, Pope Francis has condemned atomic weapons, nuclear deterrence and the growing arms trade. He said the money spent on weapons should be used to eradicate poverty and protect the environment.
