Quote of the Day by John F. Kennedy: 'It is an unfortunate fact that we can secure peace only by preparing for war' – A reflection on war from America’s 35th President

Quotes of the day sometimes feel simple, but when they come from a president speaking at a tense time in history, they carry a different weight. Today’s Quote of the Day comes from John F. Kennedy, the 35th President of the United States, who once said: “It is an unfortunate fact that we can secure peace only by preparing for war.”

The remark was delivered at the Civic Auditorium in Seattle during the 1960 presidential campaign. At the time, the Cold War between the United States and the Soviet Union was shaping global politics. Nuclear weapons, military alliances and ideological rivalry were not abstract issues. They were daily realities. Kennedy’s words reflected what was often described as a “peace through strength” approach. It was not a celebration of war. It was more a warning about the world as it stood.

Quote of the Day: What Kennedy Meant by Preparing for War

When John F. Kennedy spoke those lines in Seattle, he was arguing that military readiness was necessary to prevent conflict. The phrase “unfortunate fact” matters. He was not praising the situation. He was acknowledging it. The world, in his view, had reached a point where weakness could invite aggression.


During the campaign speech, Kennedy spoke about the need for new defense goals and about challenging the Soviet Union. The United States, he believed, could not afford to appear unprepared. In the Cold War climate, deterrence was seen as the main tool to avoid a larger catastrophe. Preparing for war, in that sense, was meant to stop war from happening at all.

The Quote of the Day still circulates widely because it touches on a difficult question: can peace exist without strength? Kennedy seemed to think that in 1960, the answer was no. The balance of power, especially with nuclear weapons involved, required visible readiness.

John F. Kennedy on War and Peace

Kennedy did not speak only about military preparedness. In fact, many of his most remembered lines focus on peace and the danger of war. He once said: “Mankind must put an end to war—or war will put an end to mankind.”

That sentence shows a different tone. It is direct and almost urgent. It suggests that war, especially in the nuclear age, was not something humanity could survive indefinitely.

He also urged caution in times of crisis, saying: “Let us...step back from the shadow of war and seek out the way of peace.”

These words were spoken during moments when Cold War tensions were high. They reflect a leader who understood the risks of escalation.

Another powerful line attributed to him reads: “Those who make peaceful revolution impossible will make violent revolution inevitable.”

Here, Kennedy addressed political systems that block reform. He warned that denying peaceful change could lead to unrest and conflict.

And in another statement, he made his position even clearer about weapons themselves: “The weapons of war must be abolished before they abolish us.”

Taken together, these quotes show that Kennedy’s thinking was not limited to military buildup. He believed strength was necessary, but he also feared the destructive capacity of modern weapons. The Quote of the Day about preparing for war sits alongside these appeals for peace, not separate from them.

Early Life of John F. Kennedy

John Fitzgerald Kennedy was born on May 29, 1917, in Brookline, Massachusetts, to Rose Kennedy and Joseph P. Kennedy. He was the second of nine children in a prominent Irish Catholic family. His father was a wealthy businessman and later served as U.S. ambassador to Great Britain.

Kennedy’s childhood was marked by frequent illness. He was seriously sick several times and was even given last rites on more than one occasion. Despite ongoing health problems, he attended private schools, including Choate, and later studied at Harvard University. His senior thesis about Britain’s delay in entering World War II was published in 1940 under the title Why England Slept.

During World War II, Kennedy served in the U.S. Navy. He commanded a Patrol Torpedo boat, PT-109, in the Pacific. In 1943, his boat was struck by a Japanese destroyer. Kennedy helped rescue members of his crew and was later awarded the Navy and Marine Corps Medal for heroism. His older brother, Joseph Jr., who had been expected to enter politics, was killed during the war. After that, the family’s political hopes shifted toward John.

Political Rise and the Presidency

Kennedy entered politics in 1946, winning a seat in the U.S. House of Representatives. He later won a Senate seat in 1952. In 1953, he married Jacqueline Lee Bouvier, known as Jackie. The couple had two surviving children, Caroline and John Jr., though they also experienced personal tragedy with the loss of two children in infancy.

In 1960, Kennedy ran for president against Vice President Richard Nixon. The election was close, but Kennedy won, becoming the youngest elected president and the first Roman Catholic to hold the office.

As president, he faced immediate Cold War challenges. The failed Bay of Pigs invasion in 1961 tested his administration early. The Cuban Missile Crisis in 1962 brought the world to the edge of nuclear confrontation. During that crisis, Kennedy ordered a naval blockade of Cuba after learning that the Soviet Union was installing nuclear missiles there. After tense negotiations, the crisis ended without war.

It was in this larger Cold War setting that the Quote of the Day about preparing for war makes sense. Kennedy believed deterrence and strength were necessary tools in a divided world.

Assassination and Legacy

On November 22, 1963, while visiting Dallas, Texas, Kennedy was shot while riding in an open car. He was pronounced dead later that day. His assassination shocked the United States and much of the world. He was 46 years old.

Even though his presidency lasted less than three years, Kennedy remains one of the most discussed American leaders. Historians often point to his speeches and his handling of the Cuban Missile Crisis as defining moments.
