The War on Terror is a term commonly applied to an international military campaign which started as a result of the 11 September 2001 terrorist attacks on the United States. This resulted in an international military campaign to eliminate al-Qaeda and other militant organizations. The United Kingdom and many other NATO and non-NATO nations participated in the conflict. The phrase 'War on Terror' was first used by US President George W. Bush on 20 September 2001. The Bush administration and the Western media have since used the term to signify a global military, political, lawful, and conceptual struggle targeting both organizations designated as terrorist and regimes accused of supporting them. It was typically used with a particular focus on militant Islamists and al-Qaeda. Although the term is not officially used by the administration of US President Barack Obama, it is still commonly used by politicians, in the media and by some aspects of government officially, such as the United States' Global War on Terrorism Service Medal.
