Which war in 2001 is subjectively deemed a world war?
World war A world war, as it is commonly understood, is a large-scale war involving many of the countries of the world or many of the most powerful and populous ones. World wars span multiple countries on multiple continents, with battles fought in many theaters. While a variety of global conflicts have been subjectively deemed "world wars", such as the Cold War and the War on Terror, the term is widely and generally accepted only as it is retrospectively applied to two major international conflicts that occurred during the 20th century: World War I (1914–1918) and World War II (1939–1945).
American propaganda during World War II During active American involvement in World War II (1941–45), propaganda was used to increase support for the war and commitment to an Allied victory. Using a vast array of media, propagandists instigated hatred for the enemy and support for America's allies, urged greater public effort for war production and victory gardens, persuaded people to save some of their material so that more material could be used for the war effort, and sold war bonds. Patriotism became the central theme of advertising throughout the war, as large scale campaigns were launched to sell war bonds, promote efficiency in factories, reduce ugly rumors, and maintain civilian morale. The war consolidated the advertising industry's role in American society, deflecting earlier criticism.
