Mr. Speaker, that is truly interesting. States definitely make frequent use of nuclear weapons during a cold war, which is a struggle for power between states. Nuclear weapons are used as a form of intimidation. We need to criminalize the possession, use and disposal of nuclear or radioactive devices and the commission of acts against a nuclear facility or the operation thereof, in order to make it illegal to use nuclear weapons as a form of intimidation. If acts like these are considered crimes and the conventions are enforced in all states, including those that possess nuclear weapons, the use of this form of coercion will be reduced. If these actions are criminalized, states will no longer be able to use nuclear weapons as a form of pressure or diplomacy. Enforcing these conventions would diminish the importance of these weapons and reduce cold wars between states.
