Nuclear Weapons are now ILLEGAL!

The Nuclear Weapons Ban Treaty (NWBT) came into force on the 22nd January 2021

50 nations have agreed that they won’t possess, develop, test, use or encourage other countries to use nuclear weapons. They also agreed to help victims of nuclear weapon’s usage and testing and also agreed to clean up the environmental impact of nuclear weapons. Pope Francis is a strong supporter of the UN Treaty on the Prohibition of Nuclear Weapons and The Holy See was one of the first states to sign and ratify it.

Our government has not engaged with the Treaty process and continues to spend huge sums of money on Trident nuclear submarines. The new international law will not be binding on the UK. However previous experience with landmines and biological weapons has shown that a UN ban treaty process can nevertheless delegitimise and then eliminate these weapons globally. We need to make sure this happens!
