Office of Strategic Influence - Wikipedia, the free encyclopedia

"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 is barred from PSYOPs in the U.S."
