Social media channels and the internet allow for campaigns of disinformation and misinformation performed by agents anywhere in the world.


History


Early

Currying favor with supporters was the other side of psychological warfare, and an early practitioner of this was
Alexander the Great Alexander III of Macedon (; 20/21 July 356 BC – 10/11 June 323 BC), most commonly known as Alexander the Great, was a king of the Ancient Greece, ancient Greek kingdom of Macedonia (ancient kingdom), Macedon. He succeeded his father Philip ...

and held on to his territorial gains by co-opting local elites into the Greek administration and culture. Alexander left some of his men behind in each conquered city to introduce Greek culture and oppress dissident views. His soldiers were paid dowries to marry locals in an effort to encourage assimilation.

in the 13th century AD employed less-subtle techniques. Defeating the will of the enemy before having to attack and reaching a consented settlement was preferable to facing his wrath. The Mongol generals demanded submission to the Khan and threatened the initially captured villages with complete destruction if they refused to surrender. If they had to fight to take the settlement, the Mongol generals fulfilled their threats and massacred the survivors. Tales of the encroaching horde spread to the next villages and created an aura of insecurity that undermined the possibility of future resistance. Genghis Khan also employed tactics that made his numbers seem greater than they actually were. During night operations he ordered each soldier to light three torches at dusk to give the illusion of an overwhelming army and deceive and intimidate enemy scouts. He also sometimes had objects tied to the tails of his horses, so that riding on open and dry fields raised a cloud of dust that gave the enemy the impression of great numbers. His soldiers used arrows specially notched to whistle as they flew through the air, creating a terrifying noise. In the 6th century BCE Greek

Modern Era

Because psyops shape public opinion and public memory, the rise of the printing press and mass communication greatly increased the use of psyops for military advantage. During the Indian Wars of the 17th through 19th centuries, politicians, newspaper reports and fictional novels about Native Americans all conveyed the belief that tribes in the Northeast had "died out," and leaders of New England communities even gave speeches about the "last Indians" in New England, even as Native Americans continued to reside in these communities.


World War I

The start of modern psychological operations in war is generally dated to
World War I World War I or the First World War (28 July 1914 – 11 November 1918), also known as the Great War, was a World war, global conflict between two coalitions: the Allies of World War I, Allies (or Entente) and the Central Powers. Fighting to ...

s and posters. It was also possible to transmit propaganda to the enemy via the use of airborne leaflets or through explosive delivery systems like modified artillery or mortar rounds. At the start of the war, the belligerents, especially the British and Germans, began distributing propaganda, both domestically and on the Western front. The British had several advantages that allowed them to succeed in the battle for world opinion; they had one of the world's most reputable news systems, with much experience in international and cross-cultural communication, and they controlled much of the undersea communications cable system then in operation. These capabilities were easily transitioned to the task of warfare. The British also had a diplomatic service that maintained good relations with many nations around the world, in contrast to the reputation of the German services.

admitted to being disillusioned by the propaganda leaflets that depicted the use of German troops as mere cannon fodder. In 1915, the British began airdropping a regular leaflet newspaper '' Le Courrier de l'Air'' for civilians in German-occupied France and Belgium. At the start of the war, the French government took control of the media to suppress negative coverage. Only in 1916, with the establishment of the Maison de la Presse, did they begin to use similar tactics for the purpose of psychological warfare. One of its sections was the "Service de la Propagande aérienne" (Aerial Propaganda Service), headed by Professor Tonnelat and Jean-Jacques Waltz, an Alsatian artist code-named "''Hansi''".

World War II

Germany's '' Fall Grün'' plan of invasion of Czechoslovakia had a large part dealing with psychological warfare aimed both at the Czechoslovak civilians and government as well as, crucially, at Czechoslovakia's allies. It became successful to the point that Germany gained the acquiescence of the British and French governments to the German occupation of Czechoslovakia without having to fight an all-out war, sustaining only minimum losses in covert war before the

was intended to convince the Germans of a greater Allied military strength than was the case, through fictional field armies, faked operations to prepare the ground for invasion and "leaked" misinformation about the Allied order of battle and war plans. Elaborate naval deceptions (Operations ''Glimmer'', ''Taxable'' and ''Big Drum'') were undertaken in the English Channel. Small ships and aircraft simulated invasion fleets lying off Pas de Calais, Cap d'Antifer and the western flank of the real invasion force. At the same time Operation Titanic involved the RAF dropping fake paratroopers to the east and west of the Normandy landings. The deceptions were implemented with the use of double agents, radio traffic and visual deception. The British " Double Cross" anti-espionage operation had proven very successful from the outset of the war, and the LCS was able to use double agents to send back misleading information about Allied invasion plans.

) personnel and terrorizing any potential sympathizers or passive supporters. During the Phoenix Program, over 19,000 NLF supporters were killed. In Operation Wandering Soul, the United States also used tapes of distorted human sounds and played them during the night making the Vietnamese soldiers think that the dead were back for revenge. The Vietcong and their forces also used a program of psychological warfare during this war. Trịnh Thị Ngọ, also known as Thu Hương and Hanoi Hannah, was a Vietnamese radio personality. She made English-language broadcasts for North Vietnam directed at United States troops. During the Vietnam War, Ngọ became famous among US soldiers for her propaganda broadcasts on Radio Hanoi. Her scripts were written by the North Vietnamese Army and were intended to frighten and shame the soldiers into leaving their posts. She made three broadcasts a day, reading a list of newly killed or imprisoned Americans, and playing popular US anti-war songs in an effort to incite feelings of nostalgia and homesickness, attempting to persuade US GIs that the US involvement in the Vietnam War was unjust and immoral. A typical broadcast began as follows:
How are you, GI Joe? It seems to me that most of you are poorly informed about the going of the war, to say nothing about a correct explanation of your presence over here. Nothing is more confused than to be ordered into a war to die or to be maimed for life without the faintest idea of what's going on.

in an influence operation in Central Asia and the Middle East. Their posts, primarily in Arabic, Farsi and Russian, criticized Iran, China and Russia and gave pro-Western narratives. Data suggested the activity was a series of covert campaigns rather than a single operation. In operations in the South and East China Seas, both the United States and China have been engaged in " cognitive warfare", which involves displays of force, staged photographs and sharing disinformation. The start of the public use of " cognitive warfare" as a clear movement occurred in 2013 with China's political rhetoric.

. Daniel Lerner divides psychological warfare operations into three categories: Originally printed by George W. Stewart of New York. Alternative * White propaganda (omissions and emphasis): Truthful and not strongly biased, where the source of information is acknowledged. * Grey propaganda (omissions, emphasis and racial/ethnic/religious bias): Largely truthful, containing no information that can be proven wrong; the source is not identified. * Black propaganda (commissions of falsification): Inherently deceitful, information given in the product is attributed to a source that was not responsible for its creation. Lerner says grey and black operations ultimately have a heavy cost, in that the target population sooner or later recognizes them as propaganda and discredits the source. He writes, "This is one of the few dogmas advanced by Sykewarriors that is likely to endure as an axiom of propaganda: Credibility is a condition of persuasion. Before you can make a man do as you say, you must make him believe what you say." Consistent with this idea, the Allied strategy in World War II was predominantly one of truth (with certain exceptions). In '' Propaganda: The Formation of Men's Attitudes'', Jacques Ellul discusses psychological warfare as a common peace policy practice between nations as a form of indirect aggression. This type of propaganda drains the public opinion of an opposing regime by stripping away its power on public opinion. This form of aggression is hard to defend against because no international court of justice is capable of protecting against psychological aggression since it cannot be legally adjudicated.
"Here the propagandists is icdealing with a foreign adversary whose morale he seeks to destroy by psychological means so that the opponent begins to doubt the validity of his beliefs and actions."


Terrorism

According to Boaz Ganor, terrorism weakens the sense of security and disturbs daily life, damaging the target country's capability to function. Terrorism is a strategy that aims to influence public opinion into pressuring leaders to give in to the terrorists' demands, and the population becomes a tool to advance the political agenda.

The term psychological warfare is believed to have migrated from Germany to the United States in 1941. During World War II, the United States

defined psychological warfare broadly, stating "Psychological warfare employs ''any'' weapon to influence the mind of the enemy. The weapons are psychological only in the effect they produce and not because of the weapons themselves." The U.S. Department of Defense (DoD) currently defines psychological warfare as:

psychological operations is to induce or reinforce attitudes and behaviors favorable to US objectives. The Special Activities Center (SAC) is a division of the Central Intelligence Agency's Directorate of Operations, responsible for Covert Action and "Special Activities". These special activities include covert political influence (which includes psychological operations) and paramilitary operations.Executive Secrets: Covert Action and the Presidency, William J. Daugherty, University of Kentucky Press, 2004. SAC's political influence group is the only US unit allowed to conduct these operations covertly and is considered the primary unit in this area. A U.S. Army field manual released in January 2013 states that "Inform and Influence Activities" are critical for describing, directing, and leading military operations. Several Army Division leadership staff are assigned to “planning, integration and synchronization of designated information-related capabilities." Journalist and fiction writer P.W. Singer, author of ''Wired for War,'' teaches military leaders about how to incorporate "useful fiction" stories and narrative structure into military psyops. In September 2022, the DoD launched an audit of covert information warfare after social media companies identified a suspected U.S. military operation.
