<Li> Abdul Haq (Emir of the East Turkestan Islamic Movement) </Li> <Li> Abdullah Mansour (Emir of the East Turkestan Islamic Movement) </Li> <P> The War on Terror (WoT), also known as the Global War on Terrorism (GWOT), is an international military campaign that was launched by the U.S. government after the September 11 attacks in the U.S. in 2001 . The naming of the campaign uses a metaphor of war to refer to a variety of actions that do not constitute a specific war as traditionally defined . 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 . </P> <P> U.S. president Barack Obama and his administration (2009--2017) on a number of occasions expressly rejected the term "War on Terror", as well as the qualifier global, as being inaccurate and misleading . President Barack Obama announced on 23 May 2013 that the Global War on Terror is over, saying the military and intelligence agencies will not wage war against a tactic but will instead focus on a specific group of networks determined to destroy the U.S. On 28 December 2014, the Obama administration announced the end of the combat role of the US - led mission in Afghanistan . However, with the unexpected rise of the Islamic State of Iraq and the Levant terror group earlier that year, new operation against terror in Middle East and South Asia was announced--the Operation Inherent Resolve . </P>
