Office of Strategic Influence

The Office of Strategic Influence, or OSI, was a department created by the United States Department of Defense on October 30, 2001, to support the war on terrorism through psychological operations in targeted countries, which did not include the United States, because the Pentagon was barred from PSYOPs in the United States prior to the passing of the Smith-Mundt Modernization Act of 2012. However, BBC noted that "there is nothing to stop an American newspaper picking up a story carried abroad" in cases of news stories that were "black propaganda" with deliberately "misleading" information planted by the Pentagon under OSI. Although the closure of the office was announced by Secretary of Defense Donald Rumsfeld soon after its existence became publicly known, later comments by Secretary Rumsfeld imply that the actual operations of the OSI have continued unabated.
