When I was a little girl I used to end all my nightly prayers with the words, “And please no nuclear war, and peace on earth. Amen.” This was in the early eighties. The knowledge that weapons existed armed and ready which could annihilate all life on earth, including my Mum and my Dad and everyone I loved, kept me up at night. I still marvel at the fact that these weapons exist, just as armed and just as ready, and we just go about our lives like it’s perfectly normal.
