Why should countries that don’t have nuclear weapons care about this treaty?

Answer

The possession of nuclear weapons by some states puts the whole world at risk. Strengthening the norm against the use and possession of nuclear weapons is in the interest of all states and people.

Beyond banning and working towards the total elimination of nuclear weapons, the Treaty on the Prohibition of Nuclear Weapons contains important positive obligations for countries to receive and provide victim assistance for impacted people and environmental remediation for places impacted by nuclear weapons use and testing. The TPNW can help to ensure that affected communities receive the assistance they need.
