They were used once at the end of World War 2. If any country nuked another country it would lead to the eventual destruction of the country who used them. Nuclear Weapons cause both sides to be destroyed and no one wins. No country wants that. So Nuclear Weapons will never be used as any country who uses them will be destroyed themselves.
