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.[1] 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.[2]
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.[3][4] Some sources say OSI was authorized to use "military deception" against the public by "presenting false information, images, or statements",[5] while other sources say "This type of action was not in OSI's charter, and [this] charge was never substantiated."[6]
The OSI would have been a center for the creation of propaganda materials, but according to the leaked source, there were no plans[7] to mislead enemy forces or foreign civilian populations. After information on the office spread through US and foreign media in mid February 2002, intense discussions on purpose and scope of the office were reported. Some argue that its secretive nature and stated purposes would make the existence of such an agency hard to determine. The office was closed by Rumsfeld because of the controversy.[8] Some of its foreign responsibilities were moved to the Office of Information Activities.[9]
In March 2022, the US Department of Defense established the Influence and Perception Management Office (IPMO) with the purpose of countering misinformation and spreading pro-US propaganda. Another office called the Defense Military Deception Program Office which according to a US budget document is tasked with "sensitive messaging, deception, influence, and other operations in the information environment" was established in the same year.[10]
