Latest developments

The Holy See has on multiple occasions expressed grave concern over the catastrophic humanitarian and environmental effects of the use of nuclear weapons. In November 2017, Pope Francis maintained that 'the possession of nuclear weapons should be firmly condemned.' He also said that the existence of nuclear weapons 'creates a false sense of security that holds international relations hostage and stifles peaceful coexistence'. On 26 September 2019, Secretary of State Cardinal Pietro Parolin, said in the UN that the Holy See 'acknowledges with satisfaction the increasing number of states who have ratified the Treaty on the Prohibition of Nuclear Weapons and encourages those states who have already signed it to ratify it as soon as possible. We believe that the treaty is an important step towards a nuclear-weapons-free world and complements the NPT.' See: bit.ly/2kLlNA7, bit.ly/2obi545.

Recommendations

  • The Holy See should continue to encourage other states to adhere to the TPNW.
  • The Holy See should ensure that all the TPNW obligations are implemented domestically, through legal, administrative and other necessary measures.
