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.
Spirit of 1914 The Spirit of 1914 (German: Augusterlebnis) was the alleged jubilation in Germany at the outbreak of World War I. Many individuals remembered that euphoria erupted on 4 August 1914 after all the political parties in the Reichstag, including the previously antimilitarist Social Democratic Party of Germany (SPD), supported the war credits in a unanimous vote, later referred to as the "Burgfrieden" (literally "castle peace", but more accurately party truce). Many, particularly those in the middle class, believed Germany had ended its decades of bitter domestic political conflict. The string of military victories in the following weeks, which demonstrated what Germany could accomplish when unified and suggested that the war would be short, reinforced the ebullience. Many on the political right accordingly believed, and continued to believe into the Nazi era, that these first weeks of the war were Germany's finest hour, the German equivalent to 1789 in France. Until the 1990s, most historians took the memory of the Spirit of 1914 at face value and claimed that the enthusiasm in August 1914 was universal.
