Which war in 2001 is subjectively deemed a world war?
War on Terror The War on Terror (WoT), also known as the Global War on Terrorism (GWOT), is a metaphor of war referring to the international military campaign that was launched by the U.S. government after the September 11 attacks in the U.S. in 2001.  U.S. president George W. Bush first used the term ""war on terrorism"" on 16 September 2001, and then ""war on terror"" a few days later in a formal speech to Congress. In the latter speech, George Bush stated, "Our enemy is a radical network of terrorists and every government that supports them." The term was originally used with a particular focus on countries associated with al-Qaeda. The term was immediately criticised by such people as Richard B. Myers, chairman of the Joint Chiefs of Staff, and more nuanced ones subsequently came to be used by the Bush administration to publicly define the international campaign led by the U.S.; it was never used as a formal designation of U.S. operations in internal government documentation.
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.
