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).
Bombings of Heilbronn in World War II During World War II, the German city of Heilbronn was bombed many times by the British and the United States Air Forces. The largest air-raid occurred on December 4, 1944, but Heilbronn was targeted several times before and after until the end of World War II. In 1944 Heilbronn was attacked to a point where alarms in the city were almost daily. Altogether, an estimated 7,000 inhabitants lost their lives during the bombing.
