During the Cold War and beyond, the United States executed a vast number of secret operations that included everything from the infamous Project MK-Ultra to a heart attack gun.
In extraordinary times, the U.S. government has turned to extraordinary measures to protect its national interests. For better or for worse, American policymakers have developed ambitious — and often eyebrow-raising — covert operations to combat perceived foes at home and abroad.
During World War II, the U.S. government teamed up with the Mafia to sniff out possible Italian saboteurs. As tensions in the Cold War ratcheted up, the CIA studied mind-control, tried to turn cats into spies, and even developed a terrifying weapon called the “heart-attack gun.”
Below, discover the stories of nine shocking government operations, from coups d’état to space bombs.
Operation Underworld And Operation Husky: When The U.S. Government Teamed Up With The Mafia

Public DomainA suspicious fire aboard the SS Normandie in New York City prompted the U.S. government to develop Operation Underworld.
During World War II, the U.S. government became concerned about sabotage along the docks of New York. So, the feds developed the covert Operation Underworld and enlisted the help of an unlikely ally: the Mafia.
This improbable partnership arose from a suspicious fire aboard the SS Normandie, which erupted without definitive explanation on Feb. 9, 1942, while the ship was docked at Manhattan’s Pier 88. Concerned that the Italian immigrants who worked the dock might be loyal to Italian leader Benito Mussolini, the government appealed to the Mafia for aid.
According to History, the feds got in touch with a member of the Luciano crime family, which effectively ruled the New York ports at the time. The man suggested they reach out to the boss himself, Lucky Luciano. Luciano, then serving a lengthy prison sentence for compulsory prostitution, agreed to help in exchange for a reduced sentence.
As he promised, Luciano sent word to his men to report any suspicious activity they noticed at the docks. But that’s not all that this crime boss did to help the government during World War II.

In 1943, the Allies launched Operation Husky — an ambitious amphibious invasion of Sicily. To support the mission, the U.S. government reached out once again to Luciano and the Mafia. History reports that Luciano and other mobsters gave the government strategic maps and photographs and even put them in touch with sympathetic Sicilian civilians and Mafiosi.
Though some claim that Luciano’s role in Operation Husky was exaggerated, an official 1954 report found that Luciano had enlisted several informants to help the Allied invasion.
“Through these contacts and informants, the names of friendly Sicilian natives and even Sicilian underworld and Mafia personalities who could be trusted were obtained and actually used in the Sicilian campaign,” the report found.
On the day World War 2 ended in Europe, Luciano appealed for clemency. He was pardoned six months later and deported back to Italy.
Operation Northwoods: The Government Operation Meant To Start A War With Cuba

In 1962, top U.S. military brass formed a plan to neutralize Fidel Castro, the revolutionary communist leader who had risen to power in Cuba three years earlier. They came up with Operation Northwoods, a series of false flag attacks that they hoped would incite a war between Cuba and the United States.
Following the failed CIA-led Bay of Pigs invasion of Cuba in 1961, U.S. Air Force General Edward Lansdale, the chief of operations for the anti-Castro Cuba Project, or Operation Mongoose, appealed to the Joint Chiefs of Staff. He asked them for a “brief but precise description of pretexts which would provide justification for US military intervention in Cuba.”
The Joint Chiefs of Staff, led by U.S. Army General Lyman L. Lemnitzer, then came up with a covert operation that involved a series of false flag attacks that they code-named Operation Northwoods.

Public DomainOperation Northwoods proposed a number of false flag attacks that would provide “justification for for US military intervention in Cuba.”
Operation Northwoods offered several strategies. One suggested organizing “well-coordinated incidents… in and around Guantanamo” to make it seem like the U.S. base on the island was under attack. Rumors, “friendly” Cubans, and fake funerals could be used to make the attack seem legitimate.
Other false flag attacks included a “Remember the Maine incident,” referring to the unexplained explosion of the USS Maine in Havana Harbor in 1898, which gave the U.S. justification to go to war with Spain that same year. Sixty-four years later, the military proposed using “casualty lists” to trigger “national indignation.”
The Joint Chiefs of Staff additionally suggested developing a “Communist Cuban terror campaign,” in Washington, D.C., or Florida that would target American civilians. They also proposed sinking a boat of Cuban refugees (“real or simulated,” the proposal coldly noted), attacking Cuban refugees, setting off explosives, and planting evidence suggesting Cuba wanted to attack South America.
They even suggested faking an “incident which will demonstrate convincingly that a Cuban aircraft has attacked and shot down a chartered civil airliner.”
But although its designers presented Operation Northwoods to Defense Secretary Robert McNamara on March 13, 1962, President John F. Kennedy told Lemnitzer a few days later that he had no desire to use force against Cuba. And ultimately, Operation Northwoods never became anything more than a memo.
