The following are people I believe qualify as Psychopathic Acting Leaders based on their documented deeds
This grandfatherly looking figure worked with his brother John Foster Dulles for decades at Sullivan & Cromwell, a corporate law firm dedicated to paving the way for their client's big business profits in foreign countries. When fledgling international democracies, promoting self-determination, did things like nationalize their oil resources or institute land reform, the Dulles brothers swung into action. Allen become head of the CIA during Eisenhower's presidency, and his brother Foster became the head of the State Department making both the covert and overt foreign policy of the United States under the control of two brothers, in service to their clients.
Among other things, Allen Dulles oversaw the CIA overthrow of Mohammad Mosaddegh of Iran in 1953, replacing him with the deposed Shah of Iran, and Allen Dulles oversaw the CIA ousting of Juan Jacobo Árbenz Guzmán, the democratically elected leader of Guatemala in 1954, replacing him with military dictator, Colonel Carlos Castillo Armas. Allen Dulles recruited Nazi intelligence people, scientists and other valuable specialties into the U.S. after WWII and he also led the CIA MKULTRA project where the search for effective mind control techniques led to the extensive trials of the hallucinogen LSD on unsuspecting people and wiping people's minds clean with other drugs and reprogramming them through extensive repetitive taped suggestions.
When John F. Kennedy took office in 1960, he kept Allen Dulles on as CIA Director who then pushed the Cuban Bay of Pigs invasion that failed, according to Allen Dulles, because JFK failed to provide air cover, when in fact it was McGeorge Bundy, friend of Dulles, who gave an obscure order grounding the predawn air attack designed to destroy Castro's last two fighter aircraft, prior to the landing. Those two undamaged aircraft sank two supply ships and kept the attackers penned down until they were arrested. I believe Dulles tried to use the contrived failed landing to force Kennedy to authorize a U.S. military invasion of Cuba, but it did not work.
After this, Kennedy fired Allen Dulles but he still continued doing CIA business by being in contact with loyalist still inside the CIA. Allen Dulles had the means and the motive to organize and carry out the assassination of President John F. Kennedy, assigning blame to Lee Harvey Oswald while being outspoken as the actual leader of the Warren Commission using the Magic Bullet theory to keep the shooters to one, and the shots fired, to three, which are completely false conclusions based on numerous eye witnesses accounts.
Not to mention the fact, that according the color 8mm film, taken by Abraham Zapruder, President John F. Kennedy was shot in the forehead, from close range, blowing the back of his head off and causing his head to jerk violently back and to the left. Oswald, supposedly shot his three bullets from up and behind. L. Fletcher Prouty, who had been sent to Antarctica by General Edward Landsdale while the assassination took place, noticed from the photograph of the Book Repository building, taken on the day of the assassination, that a large number of windows were left open, indicating that the Secret Service had not prepared Dallas for the president's visit. In fact, the two secret service agents that were supposed to ride on the back bumper of the president's limo, were pulled off of their stations just prior to the motorcade heading out. It is silly to think that Lee Harvey Oswald could have ordered Secret Service agents to abandon their posts protecting the President of the United States or kept them from securing all the windows prior to his arrival but Allen Dulles could have.
Kissinger is considered by the establishment to have been an American diplomat, political scientist, geopolitical consultant, and politician who served as the U.S. Secretary Of State and National Security Advisor in the presidential administrations of Richard Nixon and Gerald Ford between 1969 and 1977. Wikipedia
However, there is so much more to the actual deeds of Kissinger which include executing some of the worst atrocities in the world. From 1969-1973, he oversaw the killing of millions in Vietnam, Laos and Cambodia authorizing massive carpet bombing in Cambodia focused on killing civilians (he personally approved all of the 3875 bombing raids there).
In Chile, Kissinger helped organize the coop ousting democratically elected Salvador Allende and replacing him with fascist dictator Augusto Pinochet whose government murdered thousands and tortured tens of thousands more during his 16 years in power.
Kissinger also armed and supported Indonesian dictator Suharto in 1975 in his invasion of East Timor and subsequent massacre and starvation of over 200,000 people. There are more such deeds that can be attributed to this lauded member of the ruling class who should rightfully be remembered as one of the biggest mass murderers of all time.
Christopher Columbus (aka Cristoforo Columbo) (1451-1506)
Columbus signed his financing agreement with Ferdinand and Isabella on April 17, 1492 which included the agreement he was to keep 10% of the “pearls, precious stones, gold, silver, spices… which may be bought, bartered, discovered, acquired, or obtained.” He never landed on the shores of America, but the Bahamas instead. In his personal journal he recorded his first impression of the natives there.
“They… brought us parrots and balls of cotton and spears and many other things, which they exchanged for the glass beads and hawks’ bells," he wrote. "They willingly traded everything they owned… They were well-built, with good bodies and handsome features… They do not bear arms, and do not know them, for I showed them a sword, they took it by the edge and cut themselves out of ignorance. They have no iron… They would make fine servants… With fifty men we could subjugate them all and make them do whatever we want.”
Columbus’s actual deeds and words were recorded by Bartolome de las Casas, a Dominican priest and writer.
After his initial discover of Haiti/Dominican Republic, Columbus left and came back with 17 ships and 1500 hundred men and a message from God to convert to the Catholic religion or else.
“They hanged 13 natives at a time in honor of Christ our Savior and the 12 apostles.”
“Straw was wrapped around their torn bodies and they were burned alive.”
“They took babies from their mother’s breast, grabbing them by their feet and smashing them against the rocks.”
“They would cut an Indian’s hands and leave them dangling by a thread.”
“and then others to the dogs and thus they were torn to pieces”
Stalin was the leader of the Soviet Union from 1924 to his death in 1953. According to Wikipedia, to eradicate accused "enemies of the working class", Stalin instituted the Great Purge, in which over a million were imprisoned, largely in the Gulag system of forced labour camps, and at least 700,000 executed between 1934 and 1939. By 1937, he had absolute control over the party and government. His totalitarian regime has been widely condemned for overseeing mass repression, ethnic cleansing, wide-scale deportation, hundreds of thousands of executions, and famines that killed millions. His most famous quotes are, “Gratitude is a sickness suffered by dogs,” “The people who cast the votes don’t decide an election, the people who count the votes do,” and, "A single death is a tragedy; a million deaths is a statistic.”
In WWII, General Lemay changed the tactics of U.S. bombing forces in Japan from destroying miliary targets to using napalm to incinerate hundreds of thousands of citizens in over 60 Japanese cities in the lead up to using nuclear bombs on Nagasaki and Hiroshima. He said about his work that, “killing Japanese didn't bother me very much at that time... I suppose if I had lost the war, I would have been tried as a war criminal.”
Talking about Korea, he said, “We went over there and fought the war and eventually burned down every town in North Korea anyway, someway or another, and some in South Korea too. Over a period of three years or so, we killed off - what - twenty percent of the population of Korea as direct casualties of war, or from starvation and exposure."
When he got to Vietnam, he had this to say about the bombing mission there, “The power systems that fuels every war making facility, the transportation system that roll stock, bridges, yards - eliminate them (big applause). Every factory and every industrial installation beginning with biggest and the best and never ending so long as there are two bricks stuck together and if necessary, the irrigation system on which food production largely depends. We must be willing to continue the bombing until we've destroyed every work of man in North Vietnam that is what it takes to win the war.”
