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:

    Actually we are a vulgar, pushing mob whose passions are easily mobilized by demagogues, newspaper men, religious quacks, agitators and such like. To call this a society of free peoples is blasphemous. What have we to offer the world besides the superabundant loot which we recklessly plunder from the earth under the maniacal delusion that this insane activity represents progress and enlightenment?
    Henry Miller (1891–1980)

    There is hardly such a thing as a war in which it makes no difference who wins. Nearly always one side stands more or less for progress, the other side more or less for reaction.
    George Orwell (1903–1950)
