A '''nuclear war''' or atomic war is a war which involves the use of [[nuclear weapon]]s, widespread or restricted. This has only happened once in human history, when the [[United States]] used nuclear bombs on the Japanese cities of [[Hiroshima]] and [[Nagasaki]] at the end of World War II. A nuclear war where both sides are armed with nuclear weapons would likely devastate Earth. | A '''nuclear war''' or atomic war is a war which involves the use of [[nuclear weapon]]s, widespread or restricted.
