War on terror

A concerted attempt by the United States and other key allies to defeat those groups considered responsible for 9/11. The ‘war on terror’ differs from conventional warfare in that the latter was fought against a distinct state and a uniformed organisation. It is also characterised by attempts to deal with rogue states and to prevent the proliferation of nuclear weapons. However, critics claim that the war on terror is almost exclusively directed at militant Islam. In 2013, President Obama declared the end of the ‘war on terror.’
