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.
Cold War (1953–62) The Cold War (1953–1962) discusses the period within the Cold War from the death of Soviet leader Joseph Stalin in 1953 to the Cuban Missile Crisis in 1962. Following the death of Stalin unrest occurred in the Eastern Bloc, while there was a calming of international tensions, the evidence of which can be seen in the signing of the Austrian State Treaty reuniting Austria, and the Geneva Accords ending fighting in Indochina. However, this "thaw" was only partial with an expensive arms race continuing during the period.
