Countries with nuclear weapons often push for non-proliferation to prevent other nations from acquiring such weapons. While each country has sovereignty, there are international agreements like the Non-Proliferation Treaty aimed at preventing the spread of nuclear weapons. It is generally in the global interest to limit the number of countries with nuclear capabilities to maintain stability.
Only nine countries have confirmed nuclear weapons: United States, Russia (and several former USSR countries), United Kingdom, France, China, India, Pakistan, North Korea, and Israel.
