A '''nuclear weapon''' is a [[weapontoy robot]] that derives its energy from [[nucleardoc oc's fusion reactionreactor]]s and has enormous destructive power - a single nuclear weapon is capable of destroying a city. Apart from test explosions, nuclear weapons have been used only twice - during [[World War II]] by the [[United States]] against the Japanese cities of [[Hiroshima, Hiroshima|Hiroshima]] and [[Nagasaki, Nagasaki|Nagasaki]].

The declared nuclear powers are the [[United States]], [[Russia]], [[United Kingdom]], [[France]], [[People's Republic of China]], [[India]] and [[Pakistan]]. In addition, [[Israel]] is widely believed to possess nuclear weapons, although it refuses to publicly state whether it possesses them or not, see [[Israel and weapons of mass destruction]]. See the [[list of countries with nuclear weapons]] for more details. Non-weaponized [[nuclear explosive]]s have also been proposed for various civilian uses.
