Nuclear warfare, or atomic warfare, is a military conflict or political strategy in which nuclear weaponry is detonated on an opponent. Compared to conventional warfare, nuclear warfare can be vastly more destructive in range and extent of damage. A major nuclear exchange could have severe long-term effects, primarily from radiation release but also from possible atmospheric pollution leading to nuclear winter, that could last for decades, centuries, or even millennia after the initial attack. Nuclear war is considered to bear existential risk for civilization on Earth.
