John F. Kennedy fired the imaginations and captured the hearts of Americans and foreign citizens as no President since the days of Franklin D. Roosevelt.    

Millions who voted for him—or against him or didn’t vote at all—still believe that, if only he had lived to be re-elected, America would have entered a truly Golden Age.

Kennedy certainly encouraged such belief. Asked for his definition of happiness, he quoted the ancient Greeks: “The full use of your powers along lines of excellence.”

More than 53 years after his death on November 22, 1963, he remains frozen in time. Assassinated at age 46, he remains forever young, vigorous and charming.

But even if he had not been assassinated, his Presidency could have ended in disaster.

After his 1953 marriage to Jacqueline Bouvier, he continued to pursue both a married and a bachelor life. Rumors of Kennedy’s extramarital affairs swirled throughout his Senatorial career and followed him into the White House.

His conquests included secretaries, wives of friends, strippers, movie stars (such as Marilyn Monroe and Marlene Dietrich) prostitutes and even a mobster’s mistress.

Various theories have been advanced for his taking such dangerous risks with his political career:

• As a victim of Addison’s Disease (insufficiency of the adrenal glands) he had been told by doctors he might not live beyond 35.
• As a result of the cortisone he took to control his Addison’s, his libido was greatly enhanced.
• After escaping death with the sinking of PT-109, he decided to cram as much excitement into his life as possible.
• His father, Joseph P. Kennedy, Sr., a notorious womanizer, had encouraged him and his three other sons to sleep with as many women as possible.

During the 1960 Presidential campaign, Frank Sinatra—who had become smitten with Kennedy and was determined to see him elected—introduced him to a “good time girl” named Judith Campbell.

Whether Kennedy knew it or not, Campbell was also sleeping with Sam Giancana—the most-feared Mafia boss in Chicago. And it wasn’t long before Giancana learned about her trysts with Kennedy.

As a favor to Sinatra, Giancana and his fellow mobsters used their powerful influence to ensure that JFK carried Illinois in 1960.

In turn, JFK’s father, Joseph P. Kennedy had promised Giancana that the Mob would get a free ride under a Kennedy Presidency.

When JFK appointed his brother, Robert, Attorney General, the latter declared war on organized crime. Giancana and his fellow hoods felt betrayed.

Giancana often raged to Campbell: “If it wasn’t for me, your boyfriend wouldn’t be President.” And having knowledge of her scandalous relationship with JFK, Giancana could have exposed Kennedy to a shocked public.

And if Giancana hadn’t done it, FBI Director J. Edgar Hoover might have.

Hoover, under relentless pressure from Robert Kennedy to crack down on the Mob, had, through illegal electronic surveillance, discovered the Giancana-Campbell-Kennedy connection.

Always fearful that he might be replaced as FBI director, Hoover had quickly alerted the Attorney General to his latest discovery in February, 1962. Neither RFK nor JFK could dare fire Hoover now.

White House telephone logs reveal that, from January, 1961 until February, 1962, Campbell phoned the White House 70 times.

After Hoover informed Robert Kennedy of Campbell’s status with the President, she made only one more call to Kennedy. It was then that the President said the affair was over.

Similarly, the President’s on-and-off affair with Marilyn Monroe put him in an equally dangerous position. Monroe’s behavior, fueled by emotional instability, alcohol and pills, became increasingly erratic. And she grew convinced that Kennedy should divorce Jackie and make her the new First Lady.

Rumors still circulate that the President sent Robert Kennedy—who was by now an old hand at cleaning up JFK’s messes—to tell Monroe their relationship was over.

Whatever secrets Monroe may have been able to reveal about her relationship with Kennedy, she took them to the grave in an overdose of alcohol and sleeping pills on August 5, 1962.

In his 1995 bestseller, The Dark Side of Camelot, investigative reporter Seymour Hersh got several former members of Kennedy’s Secret Service detail to speak about JFK’s extramarital sex life.

They revealed that they had not been allowed to search any of the women Kennedy cavorted with.

Any of these women could have injected the President with a poisonous hypodermic. Or secretly tape recorded their trysts with Kennedy for blackmail purposes.

Kennedy believed he would be re-elected in 1964—especially if his opponent was Barry Goldwater, the Republican Senator from Arizona.

And he almost certainly would have been re-elected; Lyndon Johnson scored a smashing victory over Goldwater that year.

But it’s also possible that Kennedy could have been forced to resign in disgrace over his affairs with Campbell, Monroe or any number of other women.

Such a fate overtook British Secretary of State for War John Profumo in 1962. In 1961, he had begun an affair with Christine Keeler, an attractive model. But Keeler was also bedding Yevgeney Ivanov, the senior naval attaché at the Soviet Embassy in Britain.

When the press learned about the threesome, Profumo was forced to resign, his 22-year political career destroyed.

President Kennedy’s untimely death has since fueled arguments over how, if he had lived, he would have dealt with Vietnam.  

In his memoirs, former Soviet Premier Nikita Khrushchev wrote: “Kennedy would have never let his country get bogged down in Vietnam.” 

But David Halberstam, who covered the early years of the war for The New York Times, came to a different conclusion.

David Halberstam in Vietnam

In his bestselling 1972 book, The Best and the Brightest, he wrote that although Kennedy questioned the wisdom of a combat commitment, he had never shown those doubts in public.

In public, he had expressed doubts only about the Diem regime—whether it held enough support among the Vietnamese to win the war.

His successor had to deal with Kennedy’s public statements, all supportive of the importance of Vietnam.

And it was that successor, newly-elevated President Lyndon B. Johnson, who decided, in 1965, to commit heavy military forces to protecting “freedom-loving” South Vietnam.

In short: Even if Kennedy had intended to withdraw American forces after winning re-election in 1964, he made a fatal mistake: He assumed there would always be time for him to do so.

Historian Thurston Clarke, in his 2013 book JFK’s Last Hundred Days, reached a totally different conclusion: That Kennedy planned to quietly remove American military advisers regardless of the military situation.

Clarke believes that Kennedy intended to gradually withdraw troops from Vietnam—but felt he could not afford to inflame the Right during an election year.

Essentially, the question, “What would  Kennedy have done?”—on Vietnam, civil rights, relations with the Soviet Union—lies at the heart of his continuing fascination among Americans.

For millions, the later turmoil of the 1960s remains such a traumatic memory that they assume: “America would have had to be better-off if Kennedy had lived.”

But much of Kennedy’s proposed legislation—such as his civil rights act—did not become law until President Johnson overcame conservative opposition to it.  

Johnson had first been elected to the House of Representatives in 1937, where he gained influence as a protégé of its speaker, Sam Rayburn. In 1948, he was elected to the U.S. Senate and eventually became one of its most powerful members—especially after becoming its Majority Leader in 1954.

Johnson knew the strengths and weaknesses of his political colleagues, and he ruthlessly exploited this knowledge to ensure the passage of legislation he supported.

Kennedy had served in the House from 1946 to 1952, and from 1952 to 1961 in the Senate.  But he had never been a major leader in either body.

It was as a Senator that he wrote his Pulitzer Prize-winning book, Profiles in Courage. But it was also as a Senator that he refused to vote on whether U.S. Senator Joseph R. McCarthy should be censured by his Senatorial colleagues.

In 1954, the Senate voted to condemn McCarthy, whose slanders of Communist subversion had bullied and frightened Americans for four years. McCarthy’s influence as a political figure died overnight.

Joseph P. Kennedy, the family patriarch, was a strong McCarthy supporters. And Robert F. Kennedy had briefly worked for McCarthy’s Red-baiting Senate subcommittee.

JFK’s refusal to say how he would have voted on censuring McCarthy damaged his support among liberals during the 1960 election.

Eleanor Roosevelt famously said that Kennedy should show “more courage and less profile.”

Although Lyndon Johnson’s legislative achievements as Senator and President remain unprecedented, he remains a pariah figure among Democrats.

His 1965 decision to wage all-out war in Vietnam ignited nationwide protests and elected Richard M. Nixon as President in 1968.

Like a doomed character in George Orwell’s novel, 1984, he has largely become an un-person.

Meanwhile, John F. Kennedy continues to endlessly fascinate Americans. In poll after poll they continue to rate him highly—even though he served less than three years in the White House.

Hundreds of books and thousands of articles have been written about JFK. On the big screen he’s been depicted by actors such as Cliff Robertson (PT-109), Bruce Greenwood (Thirteen Days) and James Marsden (The Butler).

On TV, he’s been portrayed by William Devane (The Missiles of October), William Petersen (The Rat Pack), Martin Sheen (Kennedy), James Franciscus (Jacqueline Bouvier Kennedy) and Cliff De Young (Robert Kennedy and His Times).

Kennedy has even appeared on Saturday Night Live (perhaps most famously in a sketch where he chides then-President Clinton for his tawdry choices as a womanizer).

He even figured in a 1986 episode of the revised Twilight Zone episode where a history professor travels back in time to prevent the JFK assassination. The result: JFK is saved but Soviet Premier Nikita Khrushchev is murdered and World War III erupts.

In 2013, the Internet Movie Database listed a total of 94 movies, mini-series. TV dramas and even comedies featuring the character of John F. Kennedy.  

Roads, bridges, tunnels, highways, parks, playgrounds and schools have been named after him.

As Thurston Clarke wrote in JFK’s Last Hundred Days: “There is no test of literary merit except survival, which is in of itself an index of majority opinion. By that standard, Kennedy was a great President.” 

John F. Kennedy became President when civil rights suddenly became a burning issue throughout the Nation.               

At Kennedy’s request, dozens of law firms sent lawyers South, so civil rights demonstrators would not lack counsel.

Prominent blacks such as Thurgood Marshall, Robert C. Weaver and George L.L. Weaver were appointed, respectively, to the Supreme Court, the Housing and House Finance Agency and the office of Assistant Secretary of Labor.

But Kennedy was highly reluctant to push for a civil rights bill addressing the overall issues of racial discrimination.

The reason: Most of the chairman of House and Senate committees were deeply conservative Southern racists–whether Republican or Democrat. They decided whether Kennedy’s foreign policy initiatives would be approved or opposed–especially his bills for increased foreign aid.

Kennedy believed he could not offend such men without jeopardizing the legacy he wanted to achieve in foreign policy.

This timidity, in turn, led many prominent blacks—such as Martin Luther King and Malcom X—to believe they would see no innovative moves on Kennedy’s part.

But events forced Kennedy’s hand.edn September 30, 1962, the President sent deputy U.S. marshals and National Guardsmen into Mississippi to restore order. Rioting had erupted when, by federal court order, James Meredith, a black, was enrolled  at the state university.

Kennedy’s problems in winning support for his civil rights program arose in the folkways of the Nation.  When laws run counter to a nation’s folkways, the laws lose.

In backing the admission of Meredith, the President chose an incident which would set off shockwaves for black rights.

Kennedy held mixed emotions about the demand for civil rights by blacks. On one hand, as an Irish Catholic, he grew up with stories about longtime discrimination against his ancestors (such as the “No Irish Need Apply” signs posted by numerous employers).

On the other hand, he had been born into a world of power and wealth, and he had to grope his way toward understanding the problems of the oppressed.

Another major confrontation broke out between Kennedy and the forces of segregation on June 11, 1963.  Alabama Governor George C. Wallace personally blocked the entrance of two black pupils to the University of Tuscaloosa.

The President, watching on TV, federalized the Alabama National Guard, which Wallace had used to ring the school.  Wallace withdrew and the students were admitted and enrolled.

That same day, Kennedy addressed the nation on the need for genuine equality for all Americans: “The question is whether we are going to treat our fellow Americans as we want to be treated.”

And he called on Congress to pass his civil rights bill, which had been stalled by the legislators.

On August 28, 1963, 200,000 civil rights demonstrators flooded Washington, D.C., for a massive rally.

Fearing that violence would erupt—embarrassing his administration and setting back the cause of civil rights—Kennedy had sought to persuade Dr. Martin Luther King, the march’s chief figure, to cancel the proposed march.

But King and his fellow organizers were determined to go through with it. They had, they said, waited too long for justice to be satisfied with anything less.

The dignity and peacefulness of the rally–and, most especially, King’s soaring “I Have a Dream” speech–won tremendous sympathy throughout the country. Kennedy met with civil rights leaders afterward to offer his support.

But Kennedy’s civil rights bill remained stalled in Congress until 1964. President Lyndon B. Johnson used the assassinated Kennedy’s new status as a martyr to gain enough support for its passage.

Meanwhile, on yet another front, the Kennedy administration was waging an unprecedented war against organized crime.

This was primarily the work of Attorney General Robert F. Kennedy. As chief counsel for the Senate Permanent Subcommittee on Investigations (1957–59), he had interrogated about 800 mobsters who had been summoned by subpoena.

And he had learned, firsthand, how ineffective the FBI and Justice Department were at bringing such powerful criminals to justice. The FBI had long steered clear of organized crime investigations, largely because its director, J. Edgar Hoover, feared corruption of his agents.

Upon taking office as Attorney General, he greatly expanded the number of attorneys assigned to the Justice Department’s Organized Crime Section. And, more important, he used his status as brother to the President to jawbone FBI Director J. Edgar Hoover into attacking the Mob.

The FBI installed illegal microphones in Mob hangouts throughout the country and started building cases against such mobsters as Sam Giancana, Santos Trafficante and Carlos Marcello.

The administration’s attack on the Mob has led some historians to believe the assassination of President Kennedy was Mob-orchestrated.

The reasons:

• Joseph P. Kennedy, the family patriarch, solicited Mob money and influence for his son’s 1960 Presidential campaign.
• Through singer Frank Sinatra, the elder Kennedy assured Chicago Mafia boss Sam Giancana that the mob would get a free ride if his son were elected President.
• The CIA, seeking any way to topple Fidel Castro, enlisted the Mafia to assassinate him.
• But Robert Kennedy, as Attorney General, ignored the Mob’s “contributions” and pressed his war against the syndicates
• As a result, mobsters felt betrayed and lusted for vengeance.
