Historically, nuclear weapons have served as a deterrent to violence with the concept of mutually-assured destruction. This means that a nuclear attaick would result in a nuclear attack in return that would jeopardize your own citizens. As a result, this has prevented conflict. However, mutually-assured destruction only works as a philosophy if both governments actually care about their people living. If there is a government that believes its righteous citizens would be better off in heaven, this might change the philosophy we will have to engage for nuclear weapon defense.

The decision on which countries can possess nuclear weapons is largely influenced by international treaties and agreements, primarily the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). Under the NPT, five countries— the United States, Russia, China, France, and the United Kingdom—are recognized as nuclear-armed states, while other countries commit not to develop or acquire nuclear weapons. Ultimately, enforcement and compliance are overseen by international bodies like the International Atomic Energy Agency (IAEA) and the United Nations, but geopolitical dynamics also play a significant role in nuclear proliferation discussions.
