World War

A world war is a war affecting most of the world's most powerful and populous countries. World wars span multiple countries on multiple continents, with battles fought in multiple theaters.

The term is usually applied to the two conflicts of unprecedented scale that occurred during the 20th century: World War I (1914–1918) and World War II (1939–1945). However, it is also sometimes applied to earlier wars and to a hypothetical future war.

Famous quotes containing the words world and/or war:

    In the planning and designing of new communities, housing projects, and urban renewal, the planners both public and private, need to give explicit consideration to the kind of world that is being created for the children who will be growing up in these settings. Particular attention should be given to the opportunities which the environment presents or precludes for involvement of children with persons both older and younger than themselves.
    Urie Bronfenbrenner (b. 1917)

    In peacetime, they had all been normal decent, cowards, frightened of their wives, trembling before their bosses, terrified at the passing of the years, but war had made them gallant. They had been greedy men. Now they were self-sacrificing. They had been selfish. Now they were generous. War isn’t hell at all. It’s man at his best, the highest morality he is capable of.
    Paddy Chayefsky (1923–1981)
