Since January 2021 Nuclear Weapons have been illegal in all respects under international law. The Treaty on the Prohibition of Nuclear Weapons (TPNW) came into force on 22 January 2021. To mark this 1st Anniversary of the signing of the Treaty, Perth Quakers are holding a short period of meditation and reflection at 2pm on Saturday 22 January beside the Peace Pole in the Rodney Gardens, Perth.
