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).
ORB survey of Iraq War casualties On Friday, 14 September 2007, ORB International, an independent polling agency located in London, published estimates of the total war casualties in Iraq since the US-led invasion of Iraq in 2003. At over 1.2 million deaths (1,220,580), this estimate is the highest number published so far. From the poll margin of error of +/-2.5% ORB calculated a range of 733,158 to 1,446,063 deaths. The ORB estimate was performed by a random survey of 1,720 adults aged 18+, out of which 1,499 responded, in fifteen of the eighteen governorates within Iraq, between August 12 and August 19, 2007. In comparison, the 2006 Lancet survey suggested almost half this number (654,965 deaths) through the end of June 2006. The Lancet authors calculated a range of 392,979 to 942,636 deaths.
