Today, January 22, 2021, the United Nations Treaty on the Prohibition of Nuclear Weapons officially goes into effect. One hundred and twenty-two nations, including the Vatican, signed the historic treaty in 2017, and in October 2020 the necessary fifty nations needed to implement it ratified the treaty. It was a moving testament to the solidarity of the global community, 75 years after the atomic bombing of Hiroshima and Nagasaki, to rid the earth of nuclear weapons.
