World War III

Hypothetical future global conflict

World War III, also known as the Third World War, is a hypothetical future global conflict subsequent to World War I (1914–1918) and World War II (1939–1945). It is widely assumed that such a war would involve all of the great powers, like its predecessors, as well as the use of nuclear weapons or other weapons of mass destruction, thus surpassing prior conflicts in geographic scope, devastation, and loss of life.
