Portugal may sign and ratify or accede to the TPNW, but will have to make changes to its policies and practices to become compliant.
The former Portuguese defence minister Nuno Severiano Teixeira was among the signatories to an open letter in September 2020 calling on current leaders in umbrella states to 'show courage and boldness' and join the TPNW.1
- Portugal should ensure that nuclear weapons do not have a role in its national defence plans and security policies. It should renounce the possession and potential use of nuclear weapons on its behalf, for instance through a declaratory statement, and refrain from endorsing future alliance statements in support of weapons of mass destruction.
- Portugal should urgently adhere to the TPNW. Until it is in a position to do so, it should welcome the TPNW as a valuable component in the global disarmament and non-proliferation architecture, work with the Treaty's states parties on practical steps towards disarmament, and attend the meetings of states parties as an observer.
